Molybdenum also be easy mechanical processing and pressure processing. All of the fine properties above make molybdenum and its alloys to be used widely in aerospace, electronics, chemicals and other key areas. However, molybdenum is easy to be oxidized at high temperature, it has low recrystallization temperature, low te
