Tungsten Alloy Rod

High Density Tungsten Alloy Rods

High-density tungsten alloy rods are indispensable for applications that require extreme density, superior strength, and reliable shielding performance. We specialize in providing high-quality, high-precision tungsten alloy rods to meet your demanding needs in aerospace, defense, medical equipment, sporting goods and radiation protection.

High density tungsten alloy, also known as heavy alloy, is a material composed of a tungsten matrix and small amounts of other metallic elements such as nickel, copper, iron, etc. It possesses an impressively high density (typically 17-18.5 g/cm³) that far exceeds that of traditional metallic materials, making it ideal for applications where counterweights, counterbalances or inertia are required. Our tungsten alloy rods are carefully selected from high-quality raw materials and refined using advanced powder metallurgy processes to ensure that each rod has excellent mechanical and physical properties.

Our high-density tungsten alloy bar advantages:

Ultimate density: Its high-density characteristics provide greater mass in a limited space, making it the preferred material for applications such as counterweights and balance blocks.

Excellent mechanical strength: It has excellent tensile strength, yield strength, and hardness, and can withstand high stress and harsh environments.

Good Machinability: Despite its high density, our tungsten alloy rods still have excellent cutting performance and can be precision machined using conventional machining methods such as turning, milling, drilling, etc.

Excellent corrosion resistance: able to resist corrosion from various acidic and alkaline media, with a long service life and low maintenance costs.

Excellent radiation shielding performance: Its high density makes it an ideal radiation shielding material, widely used in medical, nuclear and other fields.

Stable physical and chemical properties: able to maintain good performance at high temperatures, suitable for various extreme environments.

Applications of Tungsten Alloy Rods:

Aerospace: used as counterweight and balance parts for aircraft, missiles, satellites and other key components.

Defense industry: used in the manufacture of armor-piercing bombs, kinetic energy bombs and other high-performance weapons.

Medical Devices: used as shielding parts of radiation therapy equipment and balancing parts of surgical instruments.

Sporting goods: used in golf clubs, darts and other products, optimizing sports performance.

Industrial field: used in vibration dampers, inertia flywheel, mold materials, etc..

Precision instruments: used as balance hammer, adjustment block, etc., to improve the accuracy and stability of the instrument.

Nuclear industry: as radiation shielding materials, to protect personnel and equipment safety.
