Engineered for Extreme Performance

As a leading supplier based in China, we specialize in high-density tungsten heavy alloys, copper tungsten composites, tungsten carbide components, and molybdenum materials. Our products are trusted globally for their unmatched thermal stability, radiation shielding, and mechanical strength under extreme conditions.

Tungsten is the most widely used refractory metal, with a melting point of 3410°C, low thermal expansion, and excellent electrical and thermal conductivity. These properties make it ideal for lighting filaments, aerospace components, medical shielding, and high-temperature industrial tools.
