Tungsten Alloy Classification

Molybdenum tungsten alloy

Alloys containing two elements, molybdenum and tungsten, include molybdenum-based molybdenum-tungsten alloys and tungsten-based tungsten-molybdenum alloy series. This alloy can be formed in any proportion and is a complete solid solution alloy at all temperatures.

Niobium Tungsten Alloy

Niobium alloy is formed by adding a certain amount of tungsten and other elements based on niobium. Tungsten and niobium form an infinite solid solution. Tungsten is an effective strengthening element for niobium, but as the amount of tungsten added increases, the plastic-brittle transition temperature of the alloy will increase and the grains will grow significantly. Therefore, in order to obtain a high-strength niobium-tungsten alloy, the amount of tungsten added must be appropriately controlled, and at the same time, elements such as zirconium and hafnium must be added to refine the grains and reduce the plastic-brittle transition temperature. In 1961, the United States successfully developed the Nb-10W-2.5Zr alloy for the space shuttle skin, and later developed it into the Nb-10W-1Zr-0.1C alloy. In the early 1970s, China also successfully developed NbWl0Zr2.5 and NbWl0Zr1C0.1 alloys.

Carbide

Cemented carbide is the most common and important form of tungsten alloy. It is different from the previous tungsten alloys in that it is made of tungsten, carbon and cobalt, so it is often called tungsten-cobalt alloy. The most widely used tools in the industrial field are basically carbide tools, so carbide, a tungsten alloy, is also called "industrial tooth".
