If you are seeking a product or service related to metal finishing, please check these Directories: Jobshops But one thing that aluminum does not always offer is ease of workability, in particular forming/bending. by ehsvp Wed May 07, 2014 6:18 am, Powered by phpBB Forum Software phpBB Limited. Thanks again! salt spray test on these post-anodizing fabrications to learn how they fare in certified corrosion testing. This coating for most marine applications is 0.0004" thick.

Feel free to stop by my shop and pick up a free sample. Q. I found a place in Wi. but I think a 3/4" pipe wrapped around a 7" mandrel would be doable (remember that 3/4" pipe is a little over an inch in O.D.). When asked about the failure of 1 1/2 Aluminum 6061-T6 & 6063-T6 pipe when being bent, The Aluminum Association replied with, For greater bendability, 6061-T4 or 6063-T4 pipes of the same size should be considered After bending, the pipes can be strengthened by artificial aging. In the most basic of terms, if you experience material failure at a T6, try a lower temper. [affil. Yes it can be bent, I watched a tower builder buy all anodized tubing and components then bend weld and build the towers. It also comes in many different shapes including flats, rounds, and structurals. Good luck. You didn't say what you needed for a radius or for legs but heres a big selection of them. They will do custom parts. ! The pipe is 7/8" o.d , 0.065 " wall thickness. It is 1-1/4 sch. I ended up heating it up a little with a torch prior to the bend and it helped alot. It has good finishing characteristics; it is easily anodized in clear or many different colors. That stuff is much tougher to bend. This very thing was experienced when rectangular aluminum tubing was bent for the roof structure for a newly constructed NASCAR Carwash in Illinois. Come join the discussion about fishing guides, bait, safety, gear, tackle, tips, reviews, accessories, classifieds, and more! A. Thanks, Larry. material:aluminum 6063-T5 Bending 90 deg.bending radius 2.5 X D. Thanks. link to spec at Techstreet] Both need to have a C.L.R. I don't recall the company's name. Then you can heliarc weld everything and paint the welds over with silver paint. I bought the materials and built my own. Don't go spend the money on getting a shop to do it. Take it to T-Top shop, give them 20 bucks, and get some nice bends. Electric current is passed through the electrolyte and the aluminum is made the anode in this electrolytic cell; the tank is the cathode. A. Hi, Peter. ! If you dont heat it and let it cool first you take a chance of it cracking.Fill with sand and plug it so you dont get kinks. that has them but the minimum order was $100, you might contact polar tank and see if they have anything that small tubing wise. A forum community dedicated to anglers in the Texas area. Thanks. They bend lots of aluminum pipe, its called "bus work"hope this will help. A. Anodized coatings are very hard and brittle. Asking as a sculptor spending someone else's money. Maybe the cracks are small enough that the corrosion of the exposed aluminum is not an issue. A. Hi Dodo, try filling dry fine sand in the pipe and bend, it will bend without any cracks. According to "Properties of Electrodeposited Metals and Alloys" JavaScript is disabled. It can be but it's much more common that it's not. CapitalEquipment Based on that article, it seems not a problem to bend anodized alum. Our company is an anodizer of aluminum and I would disagree with the assertion that bending anodized tubing is not a problem. Forming Aluminum Sheet for a Handrail System, Bending Stainless Steel Sheet and Plate for Breweries , Successful Bending of Various Grades of Aluminum. Q. I want to know if I can anodize aluminium pipe before bending without cracking the plated area. Post Anodized coatings are thick, uniform, and considered attractive, as a result of the fairly high voltage/current that is applied, followed by controlled sealing, whereas more random corrosion can be rough and quite ugly. 1 and 1/2 inch ID. The other 2, 55 degrees. You can bend it but you need a special bender that supports the sides of the tubing, a regular steel tubing bender will make it kink. 90 degree bends are hard to do, they will fracture on you. by welderbob Tue May 06, 2014 7:02 pm, Post Either that or you will have to cut and weld to get your bends at the angle you want. The T6 represents the materials temper and its degree of hardness. 52 pieces of 8 x 4 x 1/4 Rectangular Aluminum 6061-T6 tubing was called to be bent to an 18-0 inside radius. Thanks, Michael. I would imagine that the boat towers that are being built are anodized after they are bent rather than the other way around. Its not for everyone and separates the entry level fabricator from the professional in my opinion. As Michael says, they are like an M&M or an eggshell. ! I would be very curious to see an ASTM B117 [affil. The internet is largely anonymous & unvetted; some names may be fictitious and some recommendations might be harmful. The Fora platform includes forum software by XenForo, VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. could you give me more information as to where you read it , as I think it may be quite helpful to me. A. Hi Hallvard. i know on my bender you can adjust the rods that thepipe is braced on.these need to be adjusted to the correct die used. Aluminum offers good corrosion resistance and is easily welded.

As with anything else, experience counts, and I'll trust that you are able to bend the tubing such that you get hundreds of tiny cracks instead of a few dozen large ones, and are able to avoid the ugly white discoloration that less skilled fabricators get, and which is illustrated and which you commented on in letter 25645. ehsvp, I'd use the term roller for a pyramid 3 roll 'bender' that is bending by rolling the pipe through and slowly tightening the top roller down as you go back and forth? If you have a hydraulic bender then just fill the pipe with sand and bend it. by kmorin Wed May 07, 2014 1:40 am, Post Any advice? http://shop.wagnercompanies.com/elbows/pipe-and-tube-elbows?Pipe_Size=1-1%2f2%22+Pipe&Material=AluminumJust noticed they dont have any 6061 elbows though. Please tell us your situation: marine tubing, condominium guardrail, machine component, chemical piping, etc. Q. Hi, before I spend thousands of dollars on aluminium pipes I wonder if I could ask you if 3/4" or 1" aluminium pipe (schedule 40?, series 3000-5000 alloy, T-0 annealed) can be easily, or at all, spirally wound around a 7" pipe (as a form). You need to make sure you have a alloy that will bend not all aluminum alloies will bend.If you have the right alloy it will with no problem no need to fill with sand or use a bigger shoe. Thanks. I will bend a piece for you and you can test it. In order to bring the tubing into a condition where they could be worked without chance of failure, they were sent out to be heat treated in order to reduce the materials hardness and bring it into a workable state. 2 of the bends need to be 90 degrees. Once heat treated, all 52pcs of the aluminum rectangular tubing were successfully rolled to the specified inside radius of 18-0. I agree with you and, although the referenced article discusses welding anodized aluminum, I didn't see a claim that they bend it after anodizing as John M asserts. All information presented is for general reference and does not represent a professional opinion nor the policy of an author's employer. YOU SHOULD HAVE NO PROBLEM BENDING ANODIZED PIPE, BUT YOU WILL BREAK THROUGH THE ANODIZING. Disclaimer: It's not possible to fully diagnose a finishing problem or the hazards of an operation via these pages. They bend that stuff at work into many different angles and most done in the field by hand. Some custom shops will bend it for you.

Could someone tell me if anodized alum tube is coated on the inside as well? A. I have the article Moon Image Courtesy of Calendrier Lunaire. link to book anodizing is an electrical process not a ceramic coating. The article I read was mostly about TIG welding techniques they use to weld anodized aluminum. I bent some aluminum pipe for some rails on my boat. Aluminum 6061-T6 and 6063-T6 are the most common grades and tempers of aluminum specified. (in a .pdf file) on the boat company that welds anodized aluminum in the tower manufacturing business. I have a hydraulic bender that I can use but I'm not sure if this will work without kinking the pipe. Is this aluminum conduit? Bending of the substrate is no problem as it is so soft but, the coating that encase it is so hard it is like trying to bend an M&M. 6061 material. I need to make 4- 90 degree bends. What type of corrosion are you afraid of? ! Thanks, Larry. The aluminium pipes are 25 feet long and need to wind about 3 times around the length of the form. I am a beginning fabricator of the boat towers that you mentioned and would like to read the same article you read. You need the proper tooling and experience to work with anodized material. http://www.mandrel-bends.com/catalog/contact-us.html, I am looking for 4 aluminum pipe bends. Well, I'd suggest buying one or two pipes and trying it, rather than buying thousands of dollars worth :-). Yes, anodizing does create a controlled oxidized film on the aluminum, but that does mean that the "corrosion product" created by anodizing is exactly the same as from natural corrosion. Even if it is of small wall thickness. 1.9 inch OD. Aluminum is often the material of choice by designers due to its high strength-to-weight ratio.

This material is produced for structural applications and cant be found in any temper other than T6. For a better experience, please enable JavaScript in your browser before proceeding. Isn't the surface film created by anodizing the same as what aluminium itself creates when corroding only the anodizing process makes it thicker and even? Try these guys. The anodize coating has a hardness that approaches that of diamonds. Anodizing: Aluminum is immersed in a tank containing an electrolyte having a 15% sulfuric acid concentration. I build boat towers, ladder racks, etc. It has great structural strength properties including toughness and hardness. When pressures were applied, the material failed almost immediately. I need to bend some aluminum pipe for a project. Will take a stab at itEver see any electrical substations under construction? Voltage applied across the anode and cathode causes negatively charged anions to migrate to the anode where the oxygen in the anions combines with the aluminum to form aluminum oxide (Al2O3). seems not a problem. Anodized coatings are ceramic and cannot be stretched at all. I know that anodizing also cracks from expansion of the aluminum when it is strongly heated, yet hard anodized frying pans seem to held up fine. Chemicals &Consumables

I spent my whole career designing, installing, and starting up hundreds of anodizing and plating lines, so I understand how anodizing is done. Thanks again. Often bender/rollers may encounter material failure in the form of cracking when pressures are applied, or after the material has been worked past a certain degree. Found some at a few others places but they were not in schedule 40 sizing. on Amazon] by Safranek, this is something that, to paraphrase Miss Manners, "simply isn't done". I have done it for years at the shop i worked at just put a little heat on the pipe not too much cause it will melt. everyday of my life and other products made of anodized aluminum. A. Hi, Dodo. My curiosity is not sufficient to authorize the cost of a salt spray test when I have no way of recovering the cost, but hopefully some reader may come along who wants to take you up on this. A. by ehsvp Tue May 06, 2014 12:30 pm, Post Its high strength-to-weight ratio often makes it the best choice for structural applications, but it also makes the material extremely hard and brittle and therefore not the easiest of materials to work with when it comes to bending. I probably should have used the term 'ceramic-like' rather than 'ceramic' in making the point that anodized coatings have no elasticity. Material CERTS were pulled, and it was determined that the aluminum tubes were too hard and brittle, and in the current condition they were in, could not be successfully bent without the chance of failure in every one of the 52pcs. If a lower temper isnt available then the only thing left to do is to explore the option of heat treating in order to reduce the materials hardness. They are always having to bend for lifts etc. Q. Bending anodized alum. Thanks! I have seen My towers abused by salt water after 10 years look good.

Yes you most certainly can bend this stuff after it is anodized. use a bigger die, like inch and a half, or fill it with sand. A bend to me is a die with some type of outside 'former' or way to pull the pipe/tube into the die along a turn. The shell will crack. It should do the trick for ya, heat it and then let it cool(on its own) then you can apply a little heat while bending. I think a thinner wall tubing or a lighter schedule pipe would be easier to bend. 40. of 4 or 5 inches. I have read of a Florida company that daily builds custom boat towers for large yachts from anodized aluminum pipe & tube materials and daily bends and even WELDS anodized materials including for newly ordered custom yachts, like Hatteras and Viking Yachts which were mentioned in the article.
