Molybdenum-copper alloy is an alloy material made of two metal elements, molybdenum and copper, through a fine process. This alloy combines the high conductivity of copper with the high strength and high melting point of molybdenum, so it has the advantages of high strength, high specific gravity, high temperature resistance, arc ablation resistance, good conductive electrothermal performance, and good processing performance.
Molybdenum lanthanum alloy, also known as high temperature molybdenum, brand MoLa, is a small amount of molybdenum doped with two lanthanum trioxide (La2O3) particles can form the so-called composite fiber structure. This particular microstructure remains stable at temperatures up to 2000°C. Therefore, molybdenum-lanthanum oxide has creep resistance even under the conditions of use.
Molybdenum-nickel alloy is an alloy composed of metal molybdenum as a matrix element and metal element nickel.
The common molybdenum-nickel alloys are NS322 nickel-molybdenum alloy material and Hastelloy B- 2(UNS N10665) nickel-molybdenum alloy material.
Tungsten titanium alloy is an alloy material composed of tungsten and titanium as the main elements. This alloy combines the high melting point and high hardness of tungsten with the light weight characteristics of titanium, so it has excellent high temperature performance and mechanical properties.
Tungsten-nickel alloy is an alloy material with unique physical and chemical properties, which is characterized by high melting point, high hardness and high corrosion resistance. The nickel content of tungsten nickel alloy is usually less than 10% or between 10% and 25%, and the rest is mainly tungsten.
Tungsten-molybdenum alloy refers to an alloy composed of tungsten and molybdenum, in which the tungsten content in the commonly used tungsten-molybdenum alloy is 30% to 50% (mass). The preparation method of tungsten molybdenum alloy is the same as that of metal molybdenum and molybdenum alloy, mainly including powder metallurgy sintering post-processing and smelting processing, which can be used to make rods, plates, wires or other profiles. The properties of tungsten-molybdenum alloys change with the increase of tungsten content. For example, the melting point of molybdenum-tungsten alloy increases with the increase of tungsten content. When the tungsten content increases to 25%, the melting point of the alloy is about 200 ℃ higher than that of pure molybdenum. In addition, the lattice constant and density of the molybdenum-tungsten alloy increase as a linear function with the increase of tungsten content, and the hardness and strength also increase with the increase of tungsten content. The highest room temperature hardness value of the alloy is between 90% and 100, and its Vickers hardness value is as high as 3530 ~ 3860MPa, which is more than double that of pure molybdenum.
