Description
Advantages of tungsten alloy:
Tungsten alloy has many special properties, such as small size with high density, high melting point, high hardness, excellent wear resistance, high ultimate tensile strength, good extension, heat resistant, good thermal stability, easy processing, corrosion resistance, good shock resistance, high radiation absorption capacity, excellent impact and crack resistance.
Tungsten Alloy cube Introduction:
1.Applications of Tungsten Alloy Cubes:
Tungsten heavy alloy cube is completely non-toxic and environmentally friendly so tungsten heavy alloy cube is often used in weighting applications, especially used in pine wood derby cube to offer a pinewood derby kits. where lead is not appropriate. For example, lead has been banned in many streams, so tungsten heavy alloy cube is often substituted for lead weight on fishing flies. The high density of tungsten heavy alloy cube coupled with the non-toxic nature makes tungsten heavy alloy cube an ideal metal for this application.
