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

W-Ni-Cu high density tungsten alloys introduction

The W-Ni-Cu heavy density alloy, also known as tungsten-nickel-copper alloy, is a specialized material renowned for its exceptional density, mechanical strength, and electrical conductivity. This alloy combines the advantages of tungsten, nickel, and copper, resulting in a heavy and versatile 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 copper are added to enhance the mechanical and electrical properties of the alloy.

The W-Ni-Cu alloy is widely used in aerospace, automotive, and defense industries due to its unique combination of properties. Its high density makes it ideal for applications requiring weight balancing, such as aircraft and automotive components. The alloys excellent mechanical strength and toughness enable it to withstand extreme conditions and mechanical stress.

Additionally, the W-Ni-Cu alloy exhibits high electrical conductivity, making it suitable for electrical and electronic applications. It is commonly used in electrical contacts, circuit breakers, and heat sinks, where both high density and electrical conductivity are required.

QSAMs W-Ni-Cu bar

W-Ni-Cu high density tungsten alloys bar is a regular product for QSs tungsten product line. W-Ni-Cu 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-Cu 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.
