Tungsten discs and squares are widely used as contact materials in silicon controlled rectifier diodes, transistors and thyristors.

Tungsten washers are known for their extreme high density; because of this unique attribute, they are often used for balancing rotating parts.

Molybdenum-copper is a composite material. It has similar thermal properties to the tungsten-copper composite, but its lower density makes it more suitable for applications where weight limitations are a factor.

Molybdenum-titanium-zirconium (TZM) alloys contain small amounts of titanium and zirconium doped with small amounts of very fine carbides. This alloy functions most efficiently in temperature ranges of 700-1400°C (1292-2552°F). TZM alloy is much stronger than pure molybdenum. The crystallization temperature and creep resistance of this alloy is also much higher than pure molybdenum.
