Buying stock, aluminum, 6061 versus 6063?
I see the description on McMaster-Carr. Is there any difference
for bending? It will be used for ordinary purposes, nothing precise. Is there any difference between 6061 and 6063 that matters to a layperson? Thanks. Last time I went to Lowe's, I Wanted to buy a Johnson Level and Tool Mfg Co 6 foot or longer ruler, since it was 1/8 inch thick by 2 inch wide by 6 feet long piece of quality looking aluminum. Made in the USA. Unfortunately, Lowe's have replaced it with some Chinese junk. Anyway, that used to be a cheap way to get a decent amount of aluminum for $10 (US). It was a lot cheaper than their buttery stock aluminum. |

Yes, if either is hardened (T6), it will crack when bending. Heating either alloy will destroy the heat treat and it will then
bend without cracking. Steve "John Doe" wrote in message ... I see the description on McMaster-Carr. Is there any difference for bending? It will be used for ordinary purposes, nothing precise.

I can't see a _lot_ of uses for a 6' long piece of perforated I- beam. I guess if you had a specific call for that profile, it would be useful...??? LLoyd |

Try a real hardware store next time, HD and Lowe's are engaged in a race to the bottom for quality. I know Ace here has had Johnson products. As far as aluminum stock, all of them have about the same stuff, all extruded and machines like bubblegum. I have run across a few chunks at one store, now out of business, that had "6061" rolled on them in ink along with the maker's name, so it CAN be had. If all you're going to do is bend it and maybe poke some holes in it, the extruded stuff will work just fine. If you're going to put some load on it and/or run it down gravel roads with the same load on it, you might want to do some more engineering. Watch your minimum bend radius, that stuff will fall apart if you go too tight. Stan |

Clackamas Steel is a short drive from here, and in addition to the big yard of rusty steel, they have a "brass shed" and an "aluminum shed". There's a good selection of both machinable and bendable aluminum in there -- my usual task on entering the building is to restrain myself from trying to buy the whole damn thing! -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Do you need to implement control loops in software?

There's very little difference in the weldability of 6061 and 6063. I've never tried welding an aluminum rule. g -- Ned Simmons |

Steve I missed the original thread but saw your reply, did the OP require a very tight bend which could lead to cracking?. I've bent 2" x 3/8" IIRC 6082 -T6, certainly T6, in a broad radius, about 5", and that worked fine, I did have a 2m cheater on it to get the leverage. For a tight bend on sheet I would assume cracking especially if bent parallel to the grain. "John Doe" wrote in message ... I see the description on McMaster-Carr.

I researched this pretty thoroughly for a customer a few years ago. They received a large shipment of custom extrusions that were supposed to be 6061, but there was a mixup and the mill ran 6063 instead. -- Ned Simmons |

ASM (_Metals Handbook, 9th Ed.) shows 42 ksi ultimate tensile and 37 ksi yield for 6061 T6. For 6063, the comparable numbers are 35 ksi and 31 ksi. There are some stronger tempers for 6063 (T83; T832). But it's primarily an extrusion alloy, with machineability and weldability for both alloys being similar. Heat treatment is almost the same for both alloys. Annealing is done at 775 deg. F; hold for 2 - 3 hours; ramp down at 50 deg. F per hour from 775 F to 500 F. Both alloys indicate 12% elongation at the T6 temper, so neither one is very good for making tight bends in the hard condition. -- Ed Huntress |
