Molybdenum lanthanum, molybdenum niobium alloy and pure
molybdenum products, rare earth molybdenum products have more advantages, widely used in metallurgy, machinery, petroleum, chemical industry, aviation, electronics and other fields. Rare earth doped molybdenum material is a new material with structure and function.
The addition of rare earth elements can not only improve the recrystallization temperature and high-temperature creep resistance of molybdenum, but also significantly reduce the plastic-brittle transition temperature of molybdenum, increase the ductility and improve the room temperature brittleness and high-temperature droop resistance of molybdenum.
1. Rare-earth molybdenum wire is mainly used as electric light source filament, EDM electrode and heating element of high temperature furnace;
2. Rare earth molybdenum plates and plates are used for stamping silicon controlled wafers, as well as vacuum tube heat insulation shield and guide plates;
3. Rare-earth molybdenum alloys can be used as high quality steel thermal perforated caps, aerospace and nuclear industrial materials, X-ray poles, die casting molds and extrusion molds;
4. Rare earth and molybdenum special-shaped products are used as glass melting electrode, rare earth smelting electrode, crucible, high-temperature sintering boat, high-temperature radiation thermal insulation screen, nozzle, guide rail, pad, etc.;
5. Rare-earth molybdenum alloys can also be used as hot cathode materials for medium and high-power vacuum tubes. The rare earth molybdenum alloy hot cathode material replaces the thorium tungsten cathode which has high working temperature, radioactive pollution and great brittleness.
