Carbide Plate

Carbide plate is one of the many materials of tungsten steel, which is made by metallurgical methods such as pulverizing, ball milling, pressing, and sintering. The composition contents of WC and CO in different uses of carbide plates are not consistent. It is widely used.

Description

UKO’s tungsten carbide plates have excellent hardness, high hardness, good wear resistance, high modulus of elasticity, high compressive strength, and good chemical stability (acid resistance, alkali resistance, high-temperature oxidation resistance) Low impact toughness, low coefficient of expansion, heat conduction, and conductivity are similar to those of iron and its alloys.

Carbide plate is suitable for making drawing dies core, wear-resistant parts, and stamping accessories, and die cores for cemented carbide automatic press. It has good strength and impact toughness, and low wear resistance. The top forging die with a large load, such as the top forging die for screw, rivet, etc., is also used for stamping dies, extrusion dies, punching dies, etc.

Pulverizing → formula according to usage requirements → wet grinding → mixing → crushing → drying → sieving → adding molding agent later → drying again → sieving to obtain mixture → granulation → pressing → shaping → sintering → shaping (blank) → flaw detection → packaging → warehousing.
Grade Recommended Use
UYW1 It has good red hardness and can withstand a certain impact load. It is an alloy with good versatility. It is suitable for the processing of difficult-to-machine steel such as heat-resistant steel, high manganese steel and stainless steel, as well as ordinary steel and cast iron.
UYW2 Abrasion resistance is second only to UYW1, its use strength is higher, can withstand greater impact load, suitable for rough machining semi-finishing of heat-resistant steel high manganese steel stainless steel and advanced alloy steel, also suitable for ordinary steel and cast steel.
UYT30 The wear resistance and running cutting speed are higher than UYT15, but the use strength is poor and the impact toughness is poor. Suitable for the finishing of carbon steel and alloy steel, such as fine-tuning of small section, fine boring, fine expansion, etc.
UYT15 The wear resistance is better than UYT5 alloy, but the impact toughness is worse than UYT5. Suitable for semi-finishing of cutting sections in steel, cast steel and alloy steel or finishing of small cutting sections
UYT14 It has high strength, good impact resistance and shock resistance, which is second to UYT5 alloy, but its wear resistance is better than UYT5. Fine turning.
UYT5 Among tungsten-cobalt-titanium alloys, the strength, impact resistance and shock resistance are the best, but the wear resistance is poor. Suitable for rough turning and semi-precision planing of carbon steel and alloy steel (including forgings, stampings, cast iron skins) during intermittent cutting.
UYG3X Among the tungsten-cobalt-titanium alloys, the wear resistance is the best, but the impact toughness is poor. It is suitable for the high-speed finishing of small sections of cast iron nonferrous metals and their alloys, crushed fire steel, and alloy steel.
UYG3 The wear resistance is second only to UYG3X, and it is more sensitive to impact and vibration. It is suitable for fine turning semi-precision turning, fine turning thread and reaming when non-ferrous metals and their alloys are continuously cut.
UYG6A It is a fine-grained alloy with good wear resistance, suitable for semi-finishing of chilled cast iron, non-ferrous metals and their alloys, as well as semi-finishing and finishing of crushed fire steel alloy steel.
UYG6X It is a fine-grained tungsten carbide alloy with higher wear resistance than UYG6, and its use strength is similar to that of YG6 alloy.
UYG6 Wear resistance is higher but lower than UYG3, impact resistance and vibration are better than UYG3X. Suitable for semi-finishing and finishing of cast iron, non-ferrous metals and alloys, non-metallic materials at medium cutting speeds.
UYG8 The use strength is high, the impact resistance and shock resistance are better than UYG6, but the wear resistance and allowable cutting speed are lower. Suitable for low-speed rough machining of cast iron, non-ferrous metals and alloys, non-metallic materials.
UYD201 It is suitable for semi-finishing and roughing of cast iron and light alloy, as well as the milling of cast iron and low alloy steel.

Different specifications and designs in tungsten carbide wear plates can be customized. The surface condition is divided as-sintered blank and grinding, which meet various application needs.

  • Used for Heat-resistant Parts, Wear-resistance parts, Anti-shielding parts, Anti-corrosion Parts.
  • Used for making progressive press tools and progressive dies of high-velocity ram machine.
  • Used for making connectors in electron industry, IC industry, and semiconductor.
  • Used for armature, stator, LED lead frame, EI silicon steel sheet, and punching mold for hardware and standard parts.

Note: As can be seen from the above SEM Pictures, the grain size of our product is uniform, most of the grain size is about 6μm, only a few small grains. The black binder phase not only solidifies the hard phase WC, but also effectively controls the growth of grains, making the microstructure of the alloy more reasonable.

The microstructure of the cemented carbide plate has an important influence on the wear resistance. The uniform microstructure is conducive to the improvement of wear resistance, and the appropriately coarse WC grains can play a good anti-wear effect, but there must be enough bonding phase to fix the hard particles so that they will not peel off the particles. The large hard particles are coated in a large area in the bonding phase, and the particles are not easy to peel off, which helps to improve the wear resistance of the material.
