Tungsten Alloys: W Ni, Fe, Cu, or Mo

Tungsten Alloy: W, Ni, Fe, Cu and Mo. These alloys contain 90 or more tungsten with nickel, iron, or copper added. Unlike pure tungsten, these materials can be conventionally machined and are less expensive. However, they cannot withstand the extremely high heat that it would take to melt pure tungsten and are not as hard. Common uses for Heavy Tungsten Alloys are: Weights Ballast32afghanistan32afghanistan
