Carbide Tool How to choose?

       1. cobalt tungsten carbide (YG series)
      Of WC and Co, it has a higher flexural strength and toughness, good thermal conductivity, cutting sharp, mainly for machining cast iron and non-ferrous metals. Fine grain tungsten carbide cobalt in cobalt content is the same, its hardness wear resistance than tungsten carbide cobalt coarse grains to high strength and toughness somewhat less suitable for processing hard cast iron. Among the most widely used YG8 carbide, carbide Balm has said, YG8 carbide containing cobalt content of 8% of common alloy is the most widely used cutting tool carbide tool materials.
       2. tungsten carbide cobalt titanium-based (YT series)
      Since TiC (titanium carbide) hardness and high melting point than the WC, the tungsten-cobalt alloy, and compared to its hardness, wear resistance, red hardness increases, the bonding temperature, strong antioxidant capacity, can reduce bonding. But poor thermal conductivity, low flexural strength, toughness suitable for processing steel and other materials. Common YT5, YT15 alloy welding class blade, welding blade-based.
       3. titanium tungsten, tantalum carbide cobalt (YW series)
      On the basis of the YT type carbide added TaC (tantalum carbide), improved flexural strength, impact toughness, high-temperature hardness, wear resistance and oxidation capacity. Either for machining steel, cast iron and non-ferrous metals can be processed. Currently used mainly for machining difficult materials heat-resistant steel, high manganese steel, stainless steel. YW series of carbide cutting tools to machine clip blade, welding blade-based, it is also commonly used cutting knife tablets.
