Materion’s Alloy 10X is a copper-cobalt-beryllium-zirconium alloy developed for improved high temperature strength and ductility. Most high-strength copper alloys lose significant strength and ductility at elevated temperature, but Alloy 10X retains those properties at temperatures up to 800°F/430°C. With its combination of desirable elevated-temperature strength and conductivity, it has superior resistance to thermal cracking. It is the copper alloy of choice for operation above 575°F/300°C where high strength is required.
