W-Ni-Fe Alloy Plate
There are two main series of commonly used high-density tungsten alloys: the W-Ni-Cu series and the W-Ni-Fe series. High-density tungsten alloys have high density, high strength, good plasticity, and machinability, good electrical and thermal conductivity, good corrosion resistance, good weldability, and excellent absorption of various rays.
Product Introduction
W-Ni-Fe alloy plate
W-Ni-Fe alloy plate is characterized by high sintering density, good strength and plasticity, and certain ferromagnetism. W-Ni-Fe alloy plate has good plasticity and machinability, good thermal and electrical conductivity, and excellent absorption capacity for γ-rays or X-rays.
