Non-Magnetic Tungsten Alloy Rod

1. What's Non-Magnetic Tungsten Alloy Rod?
Non-magnetic tungsten alloy rod generally refers to W-Ni-Cu tungsten alloy rod, which is high density tungsten alloy rod containing no iron element and featuring low magnetic permeability and non-magnetic properties. CTIA’s W-Ni-Cu tungsten alloy rod uses tungsten (W) as the matrix phase, with nickel (Ni) and copper (Cu) as binder phases. While maintaining high specific gravity, it provides non-magnetic properties, good electrical and thermal conductivity, and good machinability. The alloy can be machined into counterweight rods, structural rods, and other components for medical equipment, electronic and electrical applications, aerospace, precision instruments, and magnetic-sensitive equipment.
