Hi Guys , i have been working in a racing billet brake calipers to my racing team.

Now the design is read to be machined ,but i have some questions...

Why the most billet calipers are maden from aluminium forged 6061-t ????

I cant make forging process in my shop, so i guess, if i could use the 7075-t651 instead of forged 6061???

Why do they use 6061 so much ? Is it a cheapest material?

What is the hardness brineel diferences between 7075-t651 and forged 6061-t?

Its easy to find 7075-t651 in my country (Brazil) ,the 6061 i cant find, only importing....

Thanks guys

Hi Lourenco, How easy is it to find 7075 in Brazil ? I need machinable Aluminum but can't seem to find anything but Al 2021 in Chile. I would consider importing 7075 from Brazil, so where would I find it, and roughly what's the price per kg ?
Thanks for your help !
