ABSTRACT:
A high conductivity high temperature copper alloy containing mischmetal, phosphorus and magnesium with specific ratios among them. The alloy is free from internal copper oxides and may be annealed at elevated temperatures in hydrogen atmospheres without embrittlement. Strengths on the order of 80 KSI and conductivities on the order of 90% IACS are obtainable in cold worked material.
