Description

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. 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. Alloy 10X is also available in TF00 temper. Thicker sections and larger diameters available in TF00 temper.
