Tungsten carbide balls  and seat are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves and flow meters. These balls are also used for coining and as pivots, detents and tips for gauges and tracers. Tungsten carbide
itself is practically inert and extremely strong. Any attack is usually on the binder. Since other material is less expensive, the selection of tungsten carbide solely for corrosion resistance is usually not justified. In highly corrosive conditions, carbides with a more
resistant binder can be supplied.
Additional ball specification ball roundness : 0.0001 inch (0.003 mm) maximum; ball surface roughness : 5RA maximum; tolerance shall to be 0.001 inch (0.025mm) for all ball diameter less than 2- inchs; tolerance shall to
be 0.002 inch (0.050mm) for all ball diameter not less than 2-inchs(precision grade : excess or equal to 25).

History of HD Carbide

All it starts from 2004, when Metallurgical and Materials Engineer XieXianJian and Machinist ChenSuQuan, ZengZuoRan, followed their entrepreneurial dream and built a small workshop on the JinJi village near Petroleum Equipment city GuangHan, south west of China. Their dream was to be the "China's expert in tungsten carbide material". The desire to reach that target Tungsten Carbide products company took hold in their imagination and with years of hard work, they reached their goal and dream. HD Carbide's Tungsten Carbide products company is now in an international level and growing fast.

From the first product sample in 2010, we have past the world's most rigorous tests from John Care's laboratory in Chicago. Ever since we have past every test. During the cooperation with John Care and it being such a big international company, we have learned many advanced management concept and quality control skills which has helped us in efficiency at work, providing multi-angle improvement on our product performance and meaning that we consistently achieve our targets. With this we would like to express our appreciation and thanks to John Care. We will, as always, supply high quality, stable and speedy products.

Over the years we have strived to continue with our success and currerntly provide a number of tungsten carbide and cemented tungsten carbide cutting tools and wear parts for all industries.
