Product Description

Round Molybdenum Ring Polished Surface High Strength

Molybdenum Ring is widely used in the national defense industry, the electronic industry, aeronautics & astronautics, and mechanical engineering. The parts of the aircraft’s wings and the screening materials of the mold commonly use molybdenum.

Characteristics:

1) high melting point, high strength,

2) smooth and clean surface,

3) good conductions, small linear expansion coefficient, and good heat resistance
