Wear-resistant and corrosion-resistant parts are one of the main uses of cemented carbide.
Its properties and uses are as follows:
Grade | Performance | application |
YG3X | The most wear-resistant grade among tungsten carbide, but its impact toughness is poor | Used as a drawing die for thin metal wires, wear-resistant parts under non-impact conditions |
YG6 | Abrasion resistance is higher than YG8, but toughness is lower than YG8 | Suitable for dry lubrication and stretching of wire rod, manufacturing easily worn parts of machines and tools, etc |
YG8 | The strength is high, the impact and vibration are better than YG6, but the wear resistance is lower than YG6 | Suitable for drawing bars and tubes of steel, non-ferrous metals and their alloys, and manufacturing easily worn parts of machines and tools, such as nozzles, tips, guides, upsetting rods and piercing tools |
YG8C | a coarse-grained WC alloy, its performance is close to that of YG15 alloy, but its wear resistance is higher than that of YG15 | Suitable for steel rods and steel pipes with high compressibility. |
YG11C | a coarse-grained WC alloy, the strength is slightly better than YG15, and the wear resistance is better than YG15 | Used as a stamping die for general impact |
YG15 | The strength is higher than the above grades, but the wear resistance is lower | Suitable for drawing steel rods and steel pipes with large compressibility, stamping tools, etc. |
YG20C | Good impact toughness, not easy to fall off and crack | Suitable for cold heading dies, reducing stamping dies; stamping dies for large-size standard parts, such as cold heading screws, nuts, cold punching steel balls, bullet heads, projectile heads and cartridge cases |
YG20 | Good wear resistance and high bending strength | Suitable for making bladed stamping dies, such as watch parts, musical instrument springs; cold punching battery shells, toothpaste skins; small size steel balls, screws, nut punching dies, hot-rolled twist drill press plates |
GT35 | Has high hardness and wear resistance, but not resistant to high temperature and corrosion | Suitable for making cold heading, cold punching, cold extrusion, cold drawing and other molds, boring bars, rolls, rolling tools and fixtures, measuring tools, machine parts, wear-resistant parts, etc. |
