What are the advantages of alloy blades?
High hardness: Gane Heng alloy blade material is made of carbide with high hardness and melting point (called hard phase) and metal binder (called bonding phase) by powder metallurgy method, its hardness reaches 89～93HRA, much higher than HSS, at 5400C, the hardness can still reach 82～87HRA, the same as the hardness of HSS at room temperature (83～86HRA).
The hardness value of cemented carbide varies with the nature, number, particle size and metal bonding phase content of carbide, and generally decreases with the increase of bonding metal phase content. When the bonding phase content is the same, the hardness of YT-type alloys is higher than that of YG-type alloys, and alloys with TaC (NbC) added have higher high-temperature hardness.
Flexural strength and toughness: The flexural strength of commonly used alloy blade materials is in the range of 900 to 1500 MPa. The higher the content of metal bonding phase, the higher the flexural strength.
When the bonding agent content is the same, the strength of YG type (WC-Co) alloy is higher than that of YT type (WC-TiC-Co) alloy, and decreases with the increase of TiC content.
