Tungsten Powder (W)

Product Overview
Tungsten powder is a gray-black powder with a metallic luster, widely used in the production of cemented carbide, tungsten alloys, and high-performance materials. With an extremely high melting point (3400°C) and boiling point (5555°C), tungsten powder exhibits excellent stability in high-temperature environments. It is commonly used in powder metallurgy, tungsten alloy manufacturing, and various industrial applications, such as arc welding electrodes and light bulb components. Its heat resistance and high hardness make it the foundation for many high-strength materials.

Key Features

• High Purity: Available in 3N, 4N, and 5N purity options to meet the needs of different industries.
• Extremely High Melting Point and Hardness: Tungsten powder's melting and boiling points are much higher than most metals, making it suitable for high-temperature environments.
• Good Chemical Stability: Tungsten powder is insoluble in water and slightly soluble in nitric acid, sulfuric acid, and hydrofluoric acid, offering excellent corrosion resistance.
• Powder Metallurgy Raw Material: Used in the production of cemented carbide, tungsten alloys, and other high-strength materials, suitable for various industrial manufacturing processes.

Applications
Tungsten powder is widely used in multiple industries due to its unique properties:

• Cemented Carbide Production: Tungsten powder is the primary raw material for manufacturing cemented carbide tools (e.g., turning tools, milling cutters, drill bits, and molds) and wear-resistant materials.
• Tungsten Alloys and Special Alloys: Mixed with metals such as molybdenum, tantalum, and rhenium to create high-temperature and corrosion-resistant tungsten alloys, which are widely used in aerospace and high-performance mechanical components.
• Electronics and Electrical Applications: Used to manufacture electrical contacts, electron tubes, arc welding electrodes, and other high-temperature electronic components.
• Radiation Shielding Materials: High-density tungsten-nickel-copper alloys are used as radiation shielding materials, widely applied in the nuclear industry, medical devices, and other fields.
• Powder Metallurgy: Tungsten powder is an essential raw material for the production of powder metallurgy products.
