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.
Molybdenum is a metallic, silvery-white element which is very stable chemically but it will react with acids. The physical characteristic that makes molybdenum unique is that it has a very high melting point, 4,730 degrees Fahrenheit. This is 2,000 degrees higher than the melting point of steel.
Compared with traditional electrode materials, tungsten-based electrode materials have the characteristics of high melting point, good corrosion resistance, high density, and superior thermal and electrical conductivity, so they are widely used in the field of welding.
In order to avoid environmental pollution caused by military materials, tungsten alloy military products are gradually replacing lead and depleted uranium for bullets and armor-piercing bullets. In the military field, tungsten alloy military products are gradually becoming popular.
