1/4" 7075 rod... does it exist?
 

I finished fabbing up a new tube/rod bender last night so now I can start to play. I purchased some aluminum rod from home depot for testing, but I am guessing this is 6061. Been google g this morning looking for a source of 7075 and have not had any luck in the 1/4" Diameter size.

Anyone know of a place to get it?

Thanks...

McMaster-Carr has at a better price, $0.17 per inch if you buy in 3-ft lengths or $0.15 per inch if you buy in 6-ft lengths. The 6-ft will increase your shipping charges though.

The rod from Home Depot may not even be 6061, I remember it being pretty soft the last time I worked with it.

I would try contacting some locals on here though. If its just for a simple project you can probably pick some scrap up cheaper then online ordering. Or at least fins a local spot that you can call.

Underground Crawlers is from Colorado if that helps ya, they may be able to help ya on metal suppliers.

Cool. You guys think 7075 is over the top for chassis additions/creation? My local steel supplier has 1/4" rod in 6061 but not 7075.

You going to be welding it? IIRC 7075 isn't really weldable.

Wise point and for some of the project the answer is yes. Order made in 6061 for this stage.

I'm guessing it's not. Whenever I've had to purchase 6061 rod, I've had to get it from McMaster or Online Metals. It's actually pretty cheap but shipping ends up costing you.

If you want a source for aluminum in Colorado, check out Alreco.

Thanks for the source, I found some at metal supermart, but they close at 5 and are not open on weekends. I can't leave work during the day so.... I bent over and paid McMaster 15 bucks in shipping to have it here in time to play this weekend.

7075 is weldable, 6061 just welds a little better.

You can weld it, but it probably won't be very strong.

The big Mt. Bike manufacturers don't seem to have any issues with welding 7000 series aluminum, they've been doing for decades, along with the aerospace industry. It's just not as "consumer" friendly as 6000 series. "thumbsup"

It looks like 7005 is the common alloy used for bikes and can be welded, 7075 can't, structurally speaking.

They have tempering ovens and very specific fillers for the task. Welded 7005 and 6061 can be annealed and retempered. 7075 gets too much damage in the HAZ. To the Point: Heat Treating Aluminum Frames - Pinkbike.

For regular folk, 6061 is the best choice for welding.

When JH posted the link, I had to go visit my Mt. Bike hanging in the storage unit ( where it does me sooo much health benefit :cry:) and sure enough- 7005 tube set, not the 7075 I would have sworn it was. Damn this getting older and loosing my memory nonsense....

There are so darn many alloys of aluminum :shock: so it is pretty easy to get mixed up!

That said (speaking from experience!) welding any grade of aluminum sucks :twisted: not only does everything have to be bloody clean (literally) the risk of stress cracks and other stuff + the AC welding sound makes it all around a pretty sucky process :x
