High Density Tungsten Alloy (W-Ni-Fe) Bar

W-Ni-Fe high density tungsten alloys introduction

The W-Ni-Fe heavy density alloy, also known as tungsten-nickel-iron alloy, is a specialized material renowned for its exceptional density and mechanical properties. This alloy combines the advantages of tungsten, nickel, and iron, resulting in a heavy and robust material that finds applications in various industries.

Tungsten, with its high density and exceptional hardness, forms the primary component of the alloy, providing excellent weight-to-volume ratio and superb resistance to wear and corrosion. Nickel and iron are added to enhance the ductility and machinability of the alloy.

The W-Ni-Fe alloy is widely used in radiation shielding applications, such as in medical and nuclear industries, due to its ability to effectively attenuate and absorb radiation. Its high density allows for efficient shielding while maintaining a relatively compact size.

Furthermore, the alloys exceptional mechanical properties make it suitable for high-temperature environments, aerospace applications, and heavy-duty machinery components. It is commonly employed in the production of balance weights, vibration-damping components, projectiles, and counterweights for various industrial applications.

QSAMs W-Ni-Fe bar

W-Ni-Fe high density tungsten alloys bar is a regular product for QSs tungsten product line. W-Ni-Fe is a very important tungsten alloy. Compared with steel, bar has much higher thermal conductivity with much smaller thermal expansion coefficient. The application of W-Ni-Fe tungsten alloy are focused on its high density and hardness. Thus, high density tungsten alloys has been the most important material for armor piercing shell and fragments. It also consumed in large quantity as cutting tools and aviation industries.
