💡 The difference between SUN-11 and SUN-15

SUN-15 can be seen as an upgraded or higher strength version of SUN-11. SUN-15'shardness(Approximately 1500 HV) andmodulus of elasticity(300 GPa) is generally higher than SUN-11 (1390 HV, 280 GPa), therefore it performs better in wear resistance and impact resistance, and is more suitable for high-strength grinding and dispersion applications.
