Tungsten – Nickel - Iron / Cylinder
Description

Tungsten-Nickel-Iron alloy can be simply understood as an alloy with tungsten as the main raw material and with nickel and iron as auxiliary raw materials. Tungsten-nickel-iron alloy has a higher density, higher strength, larger thermal conductivity, and smaller linear expansion coefficient, good electrical conductivity and plasticity, excellent weldability and machining performance.
Alfa Chemistry supplies a wide range of tungsten-nickel-iron cylinders which are highly acclaimed due to its good machinability, high modulus of elasticity, high thermal conductivity and high quality. We can also customize various shapes of tungsten products according to your requirements or drawings.
