tungsten tube

Description

Advantages of tungsten alloy:

Tungsten alloy has many special properties, such as small size with high density, high melting point, high hardness, excellent wear resistance, high ultimate tensile strength, good extension, heat resistant, good thermal stability, easy processing, corrosion resistance, good shock resistance, high radiation absorption capacity, excellent impact and crack resistance.

Tungsten alloy tube Introduction:

tungsten alloy rod is non-toxic, non-polluting and safer. tungsten heavy alloy rods including tungsten nickel iron alloy (W-Ni-Fe) rod, tungsten nickel copper alloy (W-Ni-Cu) rod. Tungsten tube is mainly used as counter weight and thermocouple protection tube in the high temperature furnace and support in sapphire single crystal furnace and high temperature sintering furnace.
