Finishing Battery Cemented Carbide Die Ring wear resistance

Carbide Battery Die---Carbide Ring

WC-Co cemented carbide has the following performance characteristics:

1. High hardness and wear resistance. It is generally between HRA86 and 93, and decreases with the increase of cobalt content.

2. The flexural strength at room temperature is between 90 and 150MPa, and the higher the cobalt content, the higher the flexural strength.

3. Relatively stable chemical properties. It is resistant to acid and alkali, and does not undergo significant oxidation even at high temperatures.

4. High thermal conductivity. It is about 1 times higher than that of high-speed steel, and increases with the increase of cobalt content.

5. The thermal expansion coefficient is relatively small. It is lower than high-speed steel, carbon steel and copper, and increases with the increase of cobalt content.

6. The compressive strength is 340~560kg/mm2, the compressive strength of hot isostatically pressed cemented carbide products reaches 600 kg/mm2, while the quenched alloy tool steel is only 250~260kg/mm2.

7. High wear resistance. 15-20 times higher than the best high-speed steel.

Our Product Series include cemented carbide turning & milling cutting tools with standard and non-standard; various kinds of wear-resisting, anti-crosion precision mould and structural parts; semifinishing and precision machining of cermet and non-cermet cutting tools.

In recent years, with decades of accumulated experience and knowledge and through unremitting efforts, we’ve developed high quality Gear Cutter Series, which including: Gear Hobs series, Shaper Cutters series, Shaving Cutter series etc.

We locate in Zhuzhou city, the land of cemented carbide in China. The company has precision production equipment from key raw materials and mixtures preparation, precision forming, atmosphere and pressure control sintering, grinding and coating, and has precision measuring instruments for international quality management standard. That is why the quality of AoHua gear cutter has even exceeded that of the original world-class brand.

AoHua Tools team will serve gear cutting tools with best quality, competitive price with best delivery for our valuable customers. We look forward to your continued interest in our gear cutting tools and wish all the best to you and your family.
