Fortal

[Rustybolt]

The guy that used to sell it on the web is out of business-mouser? somebody?
Figures too. I was lookin' for some material.Damn.

That sucks. I got a really good deal from him on 7075.

Isn't fortal just a brand name for a more common kind of aircraft aluminum? There are a bunch of sellers on eBay that have various kinds of Al stock.

Darn, I kind of assumed that guy with the fortal would be around. That's too bad.

Rusty - what size material do you need? I have some around - not much - and would probably be more interested in a cool trade than an outright sale. Got anything cool? Material? Tool or part? Email the address in my profile...

Fortal is 7075-T651 aluminum made to the center of the spec.

MOUSEBAR.COM I was hoping he was just on vacation over the holidays have some backed up but golly I love to work with that stuff.

Yep. 7075 is beautiful material. Plates ring like a bell and it machines almost like brass without the problems. Stronger than mild steel at 1/3 the weight.

Hello,
FORTAL is a proprietary alloy used for metal dies. It's target market are die and moldmakers looking to substitute aluminum for steel dies.

I had someone inquire about substituting FORTAL on one of my miniature IC engine designs. Here is a cut-and-paste of part of the response:

=============================
I am not familiar with Fortal aluminum alloy, but have spent some time looking through the application manual for it (see http://www.supdie.com/products/fortal.html). Based on this look, I would be hesitant to use it. Fortal is a proprietary alloy designed for the die-making industry. It has a high Zinc content (10%), a low Endurance Limit (strength after a large number of cycles), and a low strength when heated above 400degrees (300-392 degrees for an extended period of time). It is unclear as to what state the pieces available at Mousebar.com are. (wrought or cast?) There are special requirements for tapping as well (ground taps only). Overall, I am not comfortable with substituting Fortal for 6061. (Mostly due to lack of experience with it.) If I were to choose a substitute, I would go with 2024 first, and 7075 second; however, the cost for these tends to be a bit high. 2024 stands up to high-temperature operation better than most aluminum alloys and is a good choice for pistons.
=======================================

FORTAL is NOT another name for 7075.

Hoping this helps,
Todd.

Fortal and 7075 are the exact same material and are made in the same way with the same properties. The limitations of Fortal are the limitations of 7075, and it most certainly does have limitations. Fortal is 7075-T651 temper aluminum alloy.

From www.matweb.com :

FORTAL

Component Wt. %
Al 90.07
Cr 0.23
Cu 1.6
Mg 2.5
Zn 5.6

7075
Component Wt. %
Al 87.1 - 91.4
Cr 0.18 - 0.28
Cu 1.2 - 2
Mg 2.1 - 2.9
Zn 5.1 - 6.1

As to wrought or cast, what the heck is that supposed to mean? All aluminum is cast and then further worked depending on end use and shape desired.

Fortal is a proprietary name that has been used to try and make it seem somehow "special". It's just like all the nonsense about "billet" aluminum.
