Materion Alloy 10X CuCoBeZr Alloy, TH04 Temper
Categories: Metal; Nonferrous Metal; Beryllium Alloy; Copper Alloy

Material Notes: Alloy 10X is a copper-cobalt-beryllium-zirconium alloy developed for improved high temperature strength and ductility compared to most copper alloys. Alloy 10X retains good strength and ductility at temperatures up to 800°F/430°C. With its combination of good 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.
