The main factors determining whether a material is resistant to wear: the hardness of the substrate and the bond strength inside the material The hardness of the metal is naturally much lower than the hardness of the inorganic non-metallic material, especially when the temperature is raised, the hardness and the bonding strength of the metal material are drastically lowered. SUPAMIC series of wear-resistant materials, the aggregate is made of silicon carbide, corundum and other materials, has a very high hardness, the base part is made of internationally renowned raw materials, high hardness and high strength.

Wear resistance
Compared with domestic conventional wear-resistant materials Frequent wear test, the wear resistance coefficient is stable at 3.2~4.5 cubic centimeters |
 |
The performance has passed the GB / T18301-2012 Chinese standard test, and both have achieved excellent wear resistance.
High temperature resistance
The linear thermal expansion coefficient at 20 ° C - 850 ° C is 4.4 x 10 -6 / ° C
Wear-resistant products at high temperatures, high material rigidity, virtually no change in geometry, and original design dimensions can be fully maintained throughout the life cycle.
Within a certain range, the higher the temperature, the higher the strength, and the highest temperature can withstand 1500 ° C

Corrosion and thermal shock resistance
Corrosion resistance test: Corrosion resistance test according to national standards, the test results reach excellent level (national standard)
Thermal shock resistance test: immerse 1000 ° C sample in 20 ° C water cooling, repeat this > 30 times, the sample is crack-free, not broken
