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

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 exhibits excellent strength, toughness, and machinability, making it suitable for a wide range of applications. It is commonly used in aerospace and defense industries for components such as ballast weights, vibration-damping parts, and radiation shielding materials. Its high density allows for precise weight distribution, while its mechanical strength ensures durability in demanding environments.

Additionally, the W-Ni-Cu alloys electrical conductivity makes it suitable for electrical and electronic applications. It is often utilized in electrical contacts, heat sinks, and electrical discharge machining (EDM) electrodes.

QSAMs W-Ni-Cu plate

W-Ni-Cu high density tungsten alloys plate is a regular product for QSs tungsten product line. W-Ni-Cu is a very important tungsten alloy. Compared with steel, plate 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.
