UMM provides rhenium, tungsten, platinum, molybdenum and other alloys that can be made into a series of high temperature resistant, corrosion resistant, and wear resistant alloys. Among them, Re25-W was once a space nuclear reactor material, and later developed into a better performance Re30-W —Mo30 alloy; Re-Mo and Re-Pt are used as structural materials for atomic energy reactors, which can resist corrosion of hot bodies at 1000 ℃ and can also be used for nuclear radiation shielding.
