Refractory materials, such as refractory metals, alloys, compounds, and composites, have always been developed as high-tech materials due to their unique high melting point and some other unique properties and occupy an important position in the national economy. For example, cemented carbide with WC as the hard phase has become the “Tooth” of modern industry, […]
Zirconium, a rare metal, is widely used in the fields of aerospace, military industry, nuclear reaction, and atomic energy. Generally, titanium products used in spacecraft with high corrosion resistance are far inferior to zirconium, whose melting point is around 1600 degrees, while that of zirconium is above 1800 degrees, and the melting point of zirconia […]
A tungsten alloy, also known as a high-specific tungsten alloy, is a refractory metal consisting of W-Ni-Fe, W-Ni-Cu, and W-Ni-Cu-Fe. Tungsten alloys have high melting points and are twice as dense as steel and 50 percent higher than lead. Currently, WNiFe is a popular ingredient for high-specific tungsten alloys, such as W-Ni-Fe Alloy, which can […]
