Tungsten Nickel Copper alloys (W-Ni-Cu Alloy) are made of tungsten-based two-phase composites with Ni, Cu as additions to form a ductile matrix. Tungsten Nickel Copper alloys have good machining properties, non-magnetic, excellent radiation resistance, lower expansion coefficient, which make them extensively used in radiation protection with the sensitive environment.
Advanced Refractory Metals has 20 years of experience manufacturing and distributing high-quality tungsten-nickel-copper alloys (W-Ni-Cu Alloy). Various shapes are available.

Radiation protection and guidance: Because of its high density (~18.8 g / cm3), and excellent X-ray, gamma ray absorptive capacity, excellent processability, non-magnetic, Tungsten-Nickel-Copper alloy becomes an ideal material for radiation therapy collimator and protection components.
Our tungsten alloys are clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
