I'm looking to experiment with different plate materials being cut from China, however they have a wide range of metal alloys, I do know they vary by usage and price.
So my question is, what's the standard Alu alloy used in keyboards plates and cases?
They offer - Aluminium alloy: 6061,6063,7075,5083, 5052, 7003, 303.
And - Stainless steel: 201,202,303,304,316,316L,416,431,C45, 1.2306, 1.4301.
