Introduction

Copper alloys can be classified into cast alloys and wrought alloys. Cast alloys are those that are melted and poured into their final shape. Wrought alloys are solid alloys squashed into a final shape.

Copper UNS C82600 alloy is a beryllium-copper casting alloy that exhibits better fluidity, castability and hardness than copper UNS C82500 alloy.

The following datasheet discusses the chemical composition and properties of copper UNS C82600.
