7050 has similar characteristics to 7075, however much more stable since it goes through a compression process. It can often be rough and finish machined on one side, flipped over, and fully machined on the other side with slight changes to the first side even with significant material removal.
7050 has 70,000+ psi of tensile strength. Many people see aluminum and try speeds & feeds they might try on softer alloys. It can't be done.
Treat the material like medium carbon steel for feeds / speeds.
If the threads are to have fasteners removed and inserted frequently, screw thread inserts (helicoils) should be used. Also use quality stainless fasteners along with anti-sieze lubricant or you will have problems with corrosion and galling.
