Tungsten Alloy Bar

Product Introduction

The Tungsten Alloy Bar produced by Shaanxi Chuanghui Daye Metal Material Co., Ltd. is designed to meet the demanding requirements of high-performance applications. Made from tungsten blended with nickel, iron, or copper, this material offers an ideal combination of density, strength, and machinability. With a density ranging from 16.5 to 18.75 g/cm³ and excellent thermal and electrical conductivity, the Tungsten alloy rod is widely recognized for its superior mechanical performance in extreme environments. It maintains stability under high temperature and stress conditions, making it suitable for aerospace, defense, medical, and industrial use. Each bar is available in sintered, forged, or precision-machined form according to ASTM and GB standards.

Tungsten alloy rod have special properties such as low thermal expansion and good thermal conductivity, sufficient electrical resistance, and high elastic modulus. Therefore, tungsten alloy rod are widely used in various fields. Such as support wires, import wires, printer needles, various electrodes and quartz furnaces, filaments, high-speed tools, automotive automation products, sputtering targets.

Application Advantages

1)Mechanical processing: In the process of casting cannon barrels, tungsten alloy bars are often used to make drill rods, which are drilled and expanded with a single point cutting tool to obtain precise diameter circular holes. In addition, tungsten alloy rods can also be used for cutting conical circular holes.

2) Aerospace: Tungsten alloy rods are widely used in the aerospace industry, such as as as counterweights and balancing components for aircraft control surfaces and rotor blades, counterweights for navigation systems, and balancing components for flywheels and turbine engine crankshafts. After mixing with heat-resistant steel, tungsten alloy rods can be used to manufacture high-temperature resistant components such as guns, cannons, rockets, satellites, aircraft, and ships.

3) Other applications: Tungsten alloy rods are also used for nuclear radiation shielding, gyroscope rotors, high-temperature resistant tools, etc. In addition, tungsten alloy rods have characteristics such as high density, high melting point, high hardness, high strength, low thermal expansion coefficient, high elastic modulus, wear resistance, high temperature resistance, and good electrical and thermal conductivity, making them widely used in multiple fields.​​​​​​​

Be used in a wide range of industries.
