Tungsten Ingot

Tungsten Ingot is generally the least costly metallic form and is useful in general applications. HM can manufacture tungsten ingots with the highest possible density using crystallization, solid state, and other ultra-high purification processes such as sublimation. The regular size is nominally 2-3 cm × 3-8 cm × 6-12 cm. Other sizes and shapes can be customized according to specific requirements.

Tungsten Ingot Applications

Tungsten Ingot is usually used to manufacture tungsten and tungsten alloy materials, widely applied in the following areas:

Aerospace: Critical components for jet engines and rocket propulsion.
Military: Armor-piercing ammunition, warheads, and armor.
Electronics: Vacuum tubes, filaments, and electron beam tubes.
Energy: Control rods, radiation shielding, and nuclear components.
Metalworking: Tungsten carbide tools for high hardness and wear resistance.
High-Temperature Materials: Heating elements, thermocouples, and thermal shielding.

Tungsten Ingot Packaging

The Tungsten Ingot 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.
