High Performance Grinded Tungsten Nickel Copper Alloy Rod
Tungsten heavy alloy is a kind of alloy using tungsten as matrix and adding a small amount of nickel, iron, copper, and other alloying elements, with the characteristics such as: high and adjustable density (~ 18.5g/cm3), good absorption ability of high-energy radiation (1/3 higher than the absorptivity of lead ray), low coefficient of thermal expansion (4 ~ 6×10-6/ºC), good plasticity, high strength and elasticity modulus, machinability, and weldability.
Tungsten Nickel Copper alloys also has non-magnetic property, which make them extensively used in radiation protection with sensitive environment.
Size details:
The maximum diameter we can produce h6 grinded tungsten alloy bar is 80mm.
Radiation protection and guidance:
Because of its high density (~18.8 g / cm3), and excellent X-ray, gamma ray absorptive capacity, excellent process ability, making Tungsten Nickel Iron alloy become ideal material for radiation therapy collimator and protection components.
Balance weights:
It is widely used in automobile crankshaft counterweight, oil weight, security defense, precision optical instruments, due to the magnetic properties, high proportion of tungsten copper nickel alloy especially for in the aviation electron system.
