Molybdenum - aluminum alloy is an alloy composed of molybdenum and aluminum. It has high strength and hardness, but also has good corrosion resistance. The alloy can be used in the manufacture of high-temperature structural parts, aeroengines and other components in the aerospace field, as well as in chemical, metallurgical and other fields of corrosive media equipment. The manufacture process of platinum-Al intermediate alloy is complicated, which needs to be made by powder metallurgy technology or vacuum melting technology. In the application process, it is necessary to choose different proportions of molybdenum and aluminum alloy according to different use occasions, in order to meet different needs.
