Tungsten Carbid
Tungsten carbide is an alloy material made from a hard compound of refractory metal and a binder metal by a powder metallurgy process.
Tungsten carbide has a series of excellent properties such as high hardness, wear resistance, strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remains basically unchanged even at a temperature of 500 ° C. It still has a high hardness at 1000 °C.
Carbide is widely used as a tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel, can also be used for cutting Hard-to-machine materials such as heat-resistant steel, stainless steel, high manganese steel, and tool steel.
Tungsten 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. , machining, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields.
Tungsten carbide can also be used to make rock drilling tools, mining tools, drilling tools, measuring gages, wear parts, metal grinding tools, cylinder liners, precision bearings, nozzles, metal molds (such as wire drawing dies, bolt dies, nut dies, and Various fastener molds, the excellent properties of cemented carbide gradually replaced the previous steel mold).
Hard alloy performance
1. hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC);
2. good thermal hardness (up to 900 ~ 1000 ° C, maintain 60HRC);
3. good wear resistance.
4 .Carbide tools have a cutting speed 4 to 7 times higher than that of high speed steel, and tool life is 5 to 80 times higher. Manufacturing molds and measuring tools, the life is 20 to 150 times higher than that of alloy tool steel. It can cut hard materials around 50HRC.
5. However, the hard alloy is brittle and cannot be cut. It is difficult to make a whole-tool with complicated shape. Therefore, it is often made into blades of different shapes and mounted on the body or mold body by welding, bonding, mechanical clamping, etc. use.
Shape Classification
1. Carbide ball
Tungsten carbide balls are mainly composed of high hardness refractory metal carbide (WC, TiC) micron powder, and common hard alloys are YG, YN, YT, YW series.
Commonly used hard alloy balls are mainly divided into: YG6 hard alloy ball. YG6x hard alloy ball. YG8 hard alloy ball. YG13 hard alloy ball. YG20 hard alloy ball. YN6 hard alloy ball. YN9 hard alloy ball .YN12 Carbide Ball. YT5 Carbide Ball. YT15 Carbide Ball.
2. Carbide Rod
Themain characteristics of the hard alloy rod cemented carbide rod are stable mechanical properties, easy welding, high wear resistance and high impact resistance.
Advantages: 1. Good wear resistance; 2. Good corrosion resistance; 3. High toughness; 4. Extrusion method and HIP sintering.
Uses: Carbide rods are mainly used for drills, end mills, reamer. It can also be used for cutting, stamping and measuring tools. It is used in the paper, packaging, printing, and non-ferrous metal processing industries. In addition, it is also widely used in the processing of high speed steel tools, carbide milling cutters, carbide tools, NAS cutting tools, aviation tools, carbide drills, milling core drills, high speed steel, taper milling cutters, metric Milling cutters, micro end milling cutters, hinge pilots, electronic cutters, step drills, metal cutting saws, double guaranteed diamonds, guns, angle cutters, carbide rotating jaws, etc.
Carbide rods can be used not only for cutting and drilling tools (such as micron, twiste drills, drill vertical mining tool specifications), but also for input needles, various roll worn parts and structural materials. In addition, it can be used in many fields, such as machinery, chemical, petroleum, metallurgy, electronics and defense industries.
3. Carbide Plate
hard alloy plate, with good durability and impact resistance, can be used in hardware and standard stamping dies. Carbide plates are widely used in the electronics industry, motor rotors, stators, LED lead frames, EI silicon steel sheets, etc. All carbide blocks must be checked strictly and only those without any damage, such as voids, bubbles, cracks, etc., can be shipped out.
