Carbide Rods

What are Tungsten Carbide Rods?

Solid tungsten carbide rods are widely used for high-quality solid carbide tools such as milling cutters, end-mills, drills or reamers. Specialized in tungsten carbide round bars, with an outstanding product line of solid carbide rod, we manufacture and stock unground and ground carbide rods for you. h6 polished chamfered carbide rods are most popular.

Our grade ISO K05 to K40, from machining aluminium, steel, non-ferrous metals, to titanium or we develop grade for your applications. Our 10% cobalt grade GD12 is widely used for machining aluminium and steel or general application. Our 12% cobalt grade GD14 is especially suitable for machining hard material like stainless steel and composite material. All these grades are made from Ultra-fine grain tungtsen carbide.

Sintering HIP.

The advanced computer-controlled HIP furnaces are applied to provide more pressure during the sintering process in order to get denser structure.

Powder Excellent.

Thanks to our deep cooperation with Germany H.C.Starck, we use the best powder for carbide rod in the world for all our standard grades for carbide rod manufacturing.

Production Fast.

Three different compaction methods, including extrusion, automatic press, and cold isostatic press are used for the maximum efficiency of carbide rod manufacturing.

Special Methods

Extrusion

Extrusion is the most popular method of producing carbide rods. It is a very practical way to manufacture long carbide rods like 330mm.310mm and 500mm, etc. However, its time-consuming drying process is the weakness that we have to pay attention to.

Automatic Press

Automatic pressing is the most effective ways to press short sizes like 6*50,10*75,16*100, etc. It can save cost from cutting carbide rods and it doesn’t need time to dry. So the lead time is faster than extrusion. On the other hand, long rods cannot be manufactured by this method.

Cold Isostatic Press

Cold isostatic press(CIP) is the latest technology of making carbide rods. Because it can make long bars like 400mm but it doesn’t require wax like extrusion, so it doesn’t need time to dry, either. This is the best option when making big diameters like 30mm and 40mm.
