Fine grain alloy, good wear resistance, Suitable for semifinishing of chilled cast iron, non-ferrous metal alloy, semifinishing and finishing of chilled hardened steel and alloy steel.
High strength, impact and shock resistance, higher than YC6A, but wear resistance and cutting speed comparatively lower. Suitable for processing of casting iron, non-ferrous metal and alloy as well as non- metallic materials at low cutting speed.
Fine grain alloy, good wear resistance. Used for processing hard wood, veneer board, PCB, PVC and alloy.
Fine grain alloy, with high wear resistance. high anti-bending strength, high resistance to bonding, high thermal strength. Suitable formachining of refractory alloy, stainless steel and high manganese steel, etc.
High wear resistance, high anti-bending strength, used for lead cutter in electrical line.
Conventional wear resistance, high anti-bending strength, used for steel alloy etc.
