High strength-high conductivity AMZIRC copper and AMAX-MZC alloy

AMZIRC copper (Cu-0.15Zr) and AMAX-MZC alloy (Cu-0.03Mg-0.1Ar-0.6Cr) are two copper base materials which offer combinations of strength, high softening temperature and good electrical and thermal conductivity. By varying fabrication sequences, mechanical properties can be modified to meet a variety of electronic and electrical needs in military and commercial applications. AMAX-MZC copper alloy, in the form of 30 AWG wire, attains a strength level of 85 ksi and an electrical conductivity of 80% IACS. AMZIRC copper's strength is slightly less, but compensates with better conductivity. Relatively high softening temperatures, between 425 and 500 C, are characteristic of the two materials with AMAX-MZC alloy having the better resistance to softening
