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
