Tungsten plates, sheets, and discs can undergo various surface treatments to enhance their properties for specific requirements. The most common surface treatments are as follows:

Polishing
Grinding
Coating
Oxidation
Electrolytic polish
Alkaline cleaning

Tungsten Heavy Alloy Plate/Sheet/Disc

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 Plate/Sheet/Disc Applications

High-temperature Furnaces: Tungsten plates, sheets, and discs are commonly used to manufacture heating elements in high-temperature furnaces such as tungsten boats, insulation screens, and heat generators.
Semiconductor Components: Tungsten plates, sheets, and discs are often processed into semiconductors and other implantation parts.
Sputtering Targets: Tungsten plates, sheets, and discs are also used to make tungsten sputtering targets for semiconductors.
Medical: Tungsten plates, sheets, and discs can also serve as substrate material for medical ray tube targets.

Tungsten Plate/Sheet/Disc Packaging

The Tungsten Plate/Sheet/Disc is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
