The hardness
Tungsten-base alloy has good hardness. The hardness of tungsten-base alloy will reduce with the temperature increases.
The flexural strength and toughness
The more binder in tungsten-base alloy, the higher flexural strength that tungsten-base alloy has. Tungsten-base alloy is hard brittle material. Lack of toughness is one of weaknesses of tungsten-base alloy.
Thermal conductivity
Tungsten-base alloy is featured by low thermal conductivity.
Coefficient of linear expansion
Generally speaking, coefficient of linear expansion of tungsten-base alloy is lower than that of high speed steel.
Tungsten-base alloy has cold welding resistance.
