    Default RFQ: 7075 Adapter

    Hello,

    I need a pair of these adaptors made in 7075 (T6 or T7). This is for automotive use.

    I have DWG, STL and DXF only.

    Drawings are in mm (.005 tolerances applicable).

    PM me your email address I will send digital files, will accept rough estimates without digital files.

    Looks like these are brake caliper adapters. You might want them made from 7050-T736 rather than 7075-T6, little lower ultimate properties but less affected by elevated temperatures and stress corrosion cracking.

    .005 what tolerances apply? Millimetres? Hope you're sitting down when you're opening those quotes.

    What? You don't work to microns on a general basis? Slacker...

    I try, but every time I pick the part up it keeps changing size!

    Not going to quote, but are you going to have a protective coating applied? Moisture will corrode 7075 pretty quick you can see spotting within a day and actual material loss within a couple more in damp environments.

    Yeah, when I made parts like this I used 7050, hardcoated. They've held up well (at least, nobody's complained).

    these are super precise radial brake adaptors for my space ship!

    it's .005", I should of done the drawing in inches but I started off with a handful of metric measurements.

    I plan on anodizing these for corrosion protection. But will read Millands link before I solidify the specs.

    Thanks for the input gentlemen.

    Closed. Thank you for the information we are trying these out in 7050.
