In the process of industrial manufacturing, materials are usually heated at high temperature up to thousands of degrees Celsius. Therefore, refractory metals such as tungsten, molybdenum and tantalum with higher temperature stability are preferred for furnace heating chamber and heat field materials.

Tungsten has the highest melting point (3410 ℃) and the strongest high temperature strength among all metals. It has excellent conductivity, low vapor pressure and corrosion resistance.

Molybdenum also has high melting point (2600 ℃), high temperature mechanical strength, good toughness, corrosion resistance and easy processing.

Tantalum has a melting point of 2996 ° C, good chemical resistance, excellent cold forging property, but it is easy to be processed under the condition of significantly lower than room temperature, and the recrystallization temperature is between 900 ° C and 1450 ° C.

Rare earth, including lanthanum, cerium, yttrium and so on, can make the crystal structure of the material more stable by adding tungsten molybdenum raw material powder in proportion, so as to improve the creep resistance and thermal expansion of the product in varying degrees.

We provide tungsten, molybdenum, tantalum heat field parts, using stable quality raw materials, adding rare earth elements, customized processing industry high temperature field tungsten parts, molybdenum parts, tantalum parts, including tungsten molybdenum heating body, tungsten crucible, molybdenum crucible, tungsten filament, tungsten boat, molybdenum boat, tungsten screw, molybdenum screw, tantalum screw, tungsten molybdenum tantalum nut, tungsten molybdenum tantalum washer, etc. The product has good high temperature strength, heat dissipation and corrosion resistance.

We have many years of processing experience in refractory metal industry. In the aspect of tungsten and molybdenum deep processing, hengbi can control the tolerance within 0.001mm by virtue of its technical and experience advantages, so as to ensure the accuracy and finish of products.
