Molybdenum, like tungsten, is a refractory rare metal with a melting point of 2620°C, strong interatomic bonding, small expansion coefficient, high electrical conductivity and good thermal conductivity. The influence of molybdenum on the properties of stainless steel is as follows.
TZM alloy is currently the most widely used molybdenum alloy with the best performance. TZM alloy has good high temperature strength, creep resistance and high recrystallization temperature, so it is often made into nozzles, perforated heads, molds, heat shields and grids in high-power ceramic tubes.
Tungsten alloy is an alloy composed of tungsten and other elements. Tungsten alloy wafers are made of tungsten molybdenum alloy or tungsten thorium alloy or rare earth tungsten alloy or tungsten rhenium alloy. They are often used as power semiconductor devices and electric vacuum devices.
Rolled tungsten alloy has the characteristics of high hardness and high strength, which brings a lot of inconvenience to later processing.
Appears along the edge of the pressure block, and is at a certain angle to the pressure surface, forming a neat interface called delamination. If the cobalt content of the mixture is low, the carbide hardness is high, the powder or granules are finer, the forming agent is too small or unevenly distributed, the mixture is too wet or too dry, the pressing pressure is too large, and the unit weight is too large. Layered. Improving the strength of the briquettes, reducing the internal stress and elastic aftereffect of the briquettes are effective methods to solve the delamination.
Want to be applied to high-performance, high-precision CNC machine tools, while achieving stability and better processing efficiency, generally put forward higher requirements than ordinary tools for carbide CNC tools from design to manufacturing and use.
