Tungsten boat

Advantages of tungsten boats

Advantages include exceptional heat resistance (melting point W = 3422°C), high modulus of elasticity and thermal creep resistance, the lowest coefficient of thermal expansion among metals, corrosion resistance and resistance to aggressive reagents, strength, reliability and durability.

Disadvantages

The disadvantage is the high cost of production. Tungsten is a rare metal, it is quite difficult to isolate in its pure form, it is difficult to process.

Production .

These boats are made by powder pressing of high quality tungsten with subsequent machining. The production method and the refractory nature of the material ensure high heat resistance and operational reliability of the boats. They are manufactured in any parameters and shape. Dimensions and tolerances are as agreed with the customer. The price is determined by the size, complexity of configuration and additional requirements set by the customer.

Tungsten boats used in electro-vacuum applications.
