QuestionCan you process a Cr-Cu (Approx. 0.90% Cr, Balance is Cu) alloy using the open die process and what type of resulting properties can you obtain?
Can you process a Cr-Cu (Approx. 0.90% Cr, Balance is Cu) alloy using the open die process and what type of resulting properties can you obtain? I am hoping that you would be able to achieve at least 50ksi tensile strength and a 35 ksi yield strength? Does this require heat treatment or can it be obtained only through forging?

AnswerScot Forge has processed thousands of pounds of this material and can definitely achieve the properties for which you are looking. Achieving these properties may be possible utilizing cold work to strengthen the material, however, this processing route sacrifices ductility. This is a precipitation hardening alloy which allows manipulation of the Cr within the alloy to achieve a homogenous material with the desired strength without sacrificing ductility. Scot Forge also has in-house heat treat facilities that can process this material without having to utilize an outside source.
