Small leaf spring design
Small leaf spring design
(OP)
I am looking for information on designing small leaf springs. The design needs to incorperate attachment points and the spring all into one piece without any bending to form it. The plan is to cut the spring out of sheet material in a dog bone shape. The flex would occur in the plane of the material. I am wondering what material would be best to make this out of and what sort of heat treatments would be needed?

Other flat strip spring stock materials are spring steel SAE1074, clock steel SAE1095, brass, phosphor-bronze, beryllium copper, various stainless steels, and nickel alloys. The 1074 and 1095 are not as corrosion resistant. The non-ferrous and stainless alloys are relatively corrosion resistant. Stamping out your final form from prehardened stock is preferred. However, if for some reason the material needs to be formed in a softer state, there are some materials that can be precipitate hardened or hardened and tempered after forming. 17-7 PH stainless, beryllium copper, 1074 and 1095.
