Description of Tungsten Crucible

Tungsten crucibles are produced from tungsten, a dense, silver-gray metal known for its high melting point of 3,422°C and excellent resistance to corrosion. These features make tungsten crucibles highly suitable for high-heat applications, especially in settings such as laboratories and industries that require materials to withstand severe temperatures and corrosive environments. They can be manufactured through either forging or welding processes. Seamless tungsten crucibles, valued for their superior strength, thermal durability, and corrosion resistance, are ideal for challenging high-temperature conditions.

Essential factors for selecting the right Tungsten Crucible

99.95% tungsten seamless crucible

Purity Level

Verify the purity level of the tantalum material used in the crucible, particularly for specialized applications like electronics.

Size and Capacity

Confirm the size and capacity requirements for your application

Material Compatibility

Ensure that the material does not chemically react with tungsten and confirm that tungsten itself meets the physical properties required for the working conditions, such as melting point and reactivity with the environmental atmosphere.

Customized Requirements

Provide detailed customization requirements, including drawings, working conditions, and product application information.
