Answer:

90% to 97% pure tungsten in a matrix of nickel and copper or nickel and iron.

Step-by-step explanation:

Heavy metal tungsten alloys are 90% to 97% pure tungsten in a matrix of nickel and copper or nickel and iron. The addition of these alloying elements improves both the ductility and machinability of these alloys over non-alloyed tungsten.
