Tungsten Plate/Sheet, W Metal and W Alloys

Tungsten Heavy Alloy Plate and Sheet (WNiFe, WNiCu)

Tungsten alloy plates and sheets, including WNiFe and WNiCu variants, are advanced materials known for their exceptional industrial properties. These tungsten-heavy alloys typically contain 80%-98% tungsten, along with small amounts of molybdenum, nickel, iron, and copper, providing a balance of strength and durability. Like pure tungsten, these alloy plates start as powders that undergo a series of processes including heating, mixing, pressing, and sintering to achieve their high-performance characteristics.

Tungsten Copper (WCu) Plate and Sheet

Tungsten copper plates and sheets are highly sought-after flat materials for demanding applications such as high voltage, high temperature, resistance welding, and EDM (Electrical Discharge Machining). These materials offer excellent resistance to thermal and electrical erosion, alongside superior conductivity, low thermal expansion, and excellent machinability. The combination of tungsten and copper brings together the best of both metals, making them ideal for use in environments where both strength and electrical efficiency are required.

Composition Ratios of Tungsten Copper Alloys

Tungsten copper plates and sheets are available in a variety of Cu-W ratios, including commonly used compositions like 50/50, 60/40, 70/30, 75/25, 80/20, and 90/10. These different ratios allow for easy customization of the alloy’s physical and mechanical properties to meet specific requirements. For example, a higher tungsten content provides better thermal strength and wear resistance, while a higher copper content improves electrical conductivity and machinability.

Tungsten Plate/Sheet Applications

• Production of tungsten parts for ion implantation.
• Tungsten material for heat insulation screen and heat generator of the high-temperature furnace.
• Used in the manufacture of electric vacuum devices, electric light source parts, etc.
• Used in the production of tungsten targets, sputtering tungsten targets, sintering boats, etc.

Tungsten Plate/Sheet Packing

Tungsten plates are tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage caused during storage or transportation. They will be packed in a wooden case supported with soft materials to ensure that the products thus packed will not shift inside the cases.

About Tungsten Metal and Tungsten Alloys

Tungsten metal is renowned for its high melting point, making it ideal for high-temperature applications. With a melting point exceeding 3,400°C, pure tungsten is often used in industries requiring materials that can withstand extreme heat, such as aerospace, electronics, and manufacturing. In addition to its remarkable thermal properties, tungsten heavy alloys offer enhanced corrosion resistance and high density, which are crucial in demanding environments like high-performance machinery and radiation shielding.

Tungsten is also commonly processed into various tungsten products, such as tungsten rods and tungsten tubes, which can be further refined using pressing and sintering techniques to create precise and durable products. These properties make tungsten an excellent choice for applications where both high melting capabilities and physical strength are required, providing reliability in fields like automotive, energy, and heavy industry.
