Performance:

1. Big hardness,the ROHS hardness is HRA80-90,just inferior to diamond,the wearable ability is much better than the wearable steel and stainless steel

2. Wearable ability is excellent. Equal to 266 times of manganese steel,171.5 times of high chrome cast-iron.Under the same working condition,can extend the equipment working life at least above 10 times.

3. Light weight,the bulk density is 3.6g/cm3,only half of steel,can alleviate the equipment burthen greatly.

4. Hard adhesived,good heat-resistant.
