Mauser specified 1035 for the 98 receiver.

#6061 is an easy-to-machine grade of aluminum with a nice smooth surface that’s highly weldable. There are many grades of aluminum, each with a specific application. What I’m looking for is the steel used to fabricate the Mauser 98 with. That’s a challange.

I wish gunwriters would stop pretending they know anything about metallurgy.

6061 isn’t used structurally in any aircraft. Calling it “aircraft grade” is simply ignorant.

6061 is not “aircraft grade”. It is never used structurally in aircraft (aside from some ultralights). 2024 is the most used structural alloy used in aircraft. It is too often assumed that “higher alloy number” means higher strength, which is not correct. Add in the marketing BS that is written by people who know nothing aside from marketing, and that’s how you end up with things like 6061 being referred to a “aircraft grade”.

7000 series is aircraft forging grade. It is best for hard anodizing as it can be impacted with a ball peel and not have the anodizing flake off. Try that little ditty with a 6000 series aluminum and watch what happens.
