Tungsten carbide tap is a good choice for cutting into a very abrasive material. Generally, a tap made of high quality tungsten carbide is most effective in tapping highly abrasive materials including cast iron, polymers, glass-filled polycarbonates, cast aluminum, space alloys, and nonferrous materials.

Ammonium paratungstate（APT）is white crystalline salt, with the chemical formula (NH₄)₁₀(H₂W₁₂O₄₂)•4H₂O. It is the most important raw material for most of tungsten products. Intermediates such as tungsten trioxide, tungsten blue oxide, tungstic acid, can be obtained from APT, either by thermal decomposition or chemical conversion.

Tungsten carbide wave flute milling cutter is a carbide cutting tool designed with wave edges, which is suitable for processing of ordinary steel, die steel, stainless steel, cast iron, aluminum alloy and titanium alloy.

Ammonium paratungstate (APT) is regarded as an important precursor of many tungstic product. A major product from thermal decomposition of APT is tungsten trioxide (Wo₃), which is the active phase in tungsten-based catalysts. Furthermore, it is applied in varied field of gas sensors, catalysis, electrochemistry, and photocatalysis owing to its excellent gasochromic, acidity, electrochromic and photochromic properties. Meanwhile, tungsten trioxide, with a band gap between 2.4 and 2.8 eV, is a visible light response catalyst with stability under acidic conditions, which makes it a suitable choice for the photocatalytic oxidation of organic pollutants under solar irradiation.
