Material Properties
With high melting point (2,623°C or 4,753°F), good high temperature strength, great machinability and thermal conductivity while keeping good mechanical properties at high temperatures, like tungsten, molybdenum is applied to all kinds of high temperature components including molybdenum crucible, molybdenum rod, molybdenum, molybdenum tube and a variety of product categories.
Molybdenum Alloys
Molybdenum Copper Alloy
As a pseudo-alloy, Mo-Cu alloy is composed of molybdenum and copper, the two metals that do not melt in solid solution and integrated by the advantage of the two materials. It is characterized by high thermal conductivity, low and adjustable coefficient of thermal expansion, non-magnetic, low gas content, good vacuum performance, good machining ability and outstanding properties in high temperature. It is widely used in machinery, electric power, electronics, metallurgy and other industries.
Molybdenum Tungsten Alloy
Tungsten molybdenum alloys have excellent resistance to liquid zinc corrosion effect, used to make zinc smelting industry in blender, lining pipes and containers and other components. Due to its high temperature strength, and performance close to tungsten and density that lower than tungsten, so it can be used as the corresponding high temperature rocket, missile under the condition of high temperature components, high temperature vacuum tube filament, parts and other materials.
Molybdenum Rare Earth Alloys
Adding rare earth elements could improve the molybdenum recrystallization temperature and high temperature creep resistance, and also significantly reduce the brittle transition temperature of molybdenum, increase the ductility, improve the brittleness of the room temperature brittleness and high temperature anti sagging ability. Molybdenum rare earth alloy include TZM (Titanium Zirconium Molybdenum), MHC (Molybdenum Hafnium Carbide) and MoZrO2.
Molybdenum Rhenium Alloy
Molybdenum-rhenium alloy is formed by adding different portions of rhenium into molybdenum. Molybdenum and rhenium are both refractory metals, by combining the two elements, molybdenum-rhenium alloy acquires high-temperature physical properties of rhenium, and good mechanical properties of molybdenum. Its rolling deformation degree can be up to 90%. By adding 47.5% or 41% rhenium into molybdenum to form molybdenum-rhenium alloy (nominal composition 50%Mo+50%Re), its ductility, weldability and formability are greatly improved. Even at high temperatures, molybdenum-rhenium alloy can maintain good ductility.
