A Complete Guide: Cutting Material Compatibility of Different Tungsten Carbide Blades

Time：2026-01-16

Tungsten carbide blades, with high hardness and wear resistance, are widely used in metal and non-metal cutting. Their compatibility depends on alloy composition and internal structure, and precise selection is key to improving efficiency and extending tool life. Below is a summary of four mainstream blades' core compatibility for industry practitioners.

WC-Co (YG) blades, featuring excellent toughness and impact resistance, are versatile. They suit non-ferrous metals (copper, aluminum), non-metals (wood, rubber), gray cast iron and ductile iron. For chilled cast iron, use low-cobalt models to enhance wear resistance.
In contrast, WC-TiC-Co (YT) blades excel in wear, high-temperature and red hardness. Though less tough, they perform well in cutting carbon and alloy structural steel. Coated YT blades handle 304/316 stainless steel, and cut heat-resistant steel at medium-low speeds via red hardness.

WC-TaC(NbC)-Co (YW) blades balance toughness and wear resistance, offering cost-effective all-round performance. They adapt to hard-to-process metals (stainless steel, high-temperature alloy, titanium alloy) and composites, no frequent tool replacement needed.
Ultrafine-grain carbide blades focus on high-precision cutting. With high hardness and edge retention, they process precision parts (electronic pins, metal foils) and high-hardness materials (quenched steel above HRC50, ceramic sheets) for high-end manufacturing.
Each tungsten carbide blade has unique compatibility strengths. Rational selection based on material and working conditions ensures quality, controls costs and maximizes tool value.
