Cemented carbide has high hardness, strength, wear resistance and
corrosion resistance. It is known as “industrial teeth” and is used
in the manufacture of cutting tools, cutting tools, cobalt tools
and wear parts. It is widely used in military and aerospace. In the
fields of machining, metallurgy, oil drilling, mining tools,
electronic communication, construction, etc., with the development
of downstream industries, the demand for hard alloys is increasing.
And the future of high-tech weaponry equipment manufacturing,
advances in cutting-edge science and technology, and the rapid
development of nuclear energy will greatly increase the demand for
high-tech content and high-quality stability of cemented carbide
products. The Features and the uses of cemented carbide | Mark | ISO standard | Density g/cm³ | Hardness HRA | Bending strength ≥ MPa | Grain size | Features and notice | use | | RX20 | K05 | 14.5 | 91.2 | 2100 | fine | Comprehensive properties, high hardness and high strength alloys
widely used in woodworking field | Suitable for all types of wood processing, also for the processing
of metal and non-metal materials | | RX10T | K10 | 14.5 | 91.8 | 1800 | fine | The cutting edge is sharp and the wear resistance is very good. It
is easy to crack at high temperatures. It is recommended to use
high frequency induction welding or automatic welding machine. | It is suitable for the cutting of high-density boards, high-fiber
boards and particleboards for woodworking tools. It is also
suitable for finishing and semi-finishing of cast iron, non-ferrous
metals and alloys. | | RX10 | K10 | 14.75 | 90.5 | 2200 | medium | Good wear resistance and impact resistance, resistance welding can
be used. | It is used for impact-resistant and nail-proof cutting of dry wood,
cork, mixed wood and cement board, and is suitable for all types of
forming knives in the furniture manufacturing industry. | | YG6X | K10 | 14.9 | 90.8 | 1950 | fine | Good abrasion resistance | It is suitable for machining cold hard cast iron and heat resistant
alloy, also suitable for finishing common cast iron. It is used to
make casing cemented carbide tools and wear resistant parts. | | YG6 | K20 | 14.95 | 90.5 | 2000 | medium | It has good wear resistance and impact toughness. Resistance
welding can be used, but the welding temperature should not be too
high. | It is suitable for the processing of ordinary cutting wood saws,
cast iron aluminum profiles and copper rods. | | YG8 | K20 | 14.80 | 89.5 | 2000 | medium | It has good wear resistance and impact toughness. Resistance
welding can be used, but the welding temperature should not be too
high. | It is suitable for the processing of non-ferrous metal profiles,
dry wood, cork and hardware tools. Suitable for making ordinary
sawtooth, it can also be used to make wear parts, general holes and
metal processing. | | YG8Ak | K20 | 14.75 | 90.0 | 2200 | medium | Wear resistance and hardness are good, resistance welding can be
used, but welding temperature should not be too high. | Suitable for the processing of hardwood and ordinary wood | | YG8C | K30 | 14.75 | 88.5 | 2300 | thick | Good impact toughness | Suitable for artificial marble, common wood with weeds, weeds and
thickets. |
