Coppertungsten Wikipedia

Coppertungsten tungstencopper, CuW, or WCu is a mixture of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite instead of a true alloy. The material combines the properties of both metals, resulting in a ...

What is Tungsten and Should I Buy It Jewelry Guide

Tungsten in its pure form cannot be used in jewelry. Instead, it is formed into a metal, consisting of approximately 85 tungsten and 15 carbon, nickel or cobalt which is known as tungsten carbide. Because tungsten is very brittle, mixing it with carbon reduces this characteristic, making the metal more durable and easier to work with.
