The physical properties of the cemented carbide are 3 times higher than steel. It can be made into a variety of products. The commonly used tungsten carbide products include carbide plates, rods, dies, rotary burr, wear parts, etc.
Tungsten carbide rod
Carbide rod is a new technology and new material, mainly used in the manufacture of metal cutting tools, wood, plastics and other industries that require hardness and wear resistance & corrosion resistance. It has stable mechanical properties, easy welding, high wear resistance and high impact resistance.
Applications
Cemented carbide rods are mainly used for drill bits, end mills, and reamers. It can also be suitable for cutting, stamping and measuring tools. It is Applicable in paper-making, packaging, printing, and non-ferrous metal processing industries.
Grades YG6, YG8, YG6X are more wear-resistant than MK6. It can be used for hard wood, processing aluminum alloy profiles, brass rods and cast iron, etc. YG10 is resistant to abrasion, knocking, and is used for processing hard wood, soft wood, ferrous metals and non-ferrous metals.
Tungsten carbide rods can be used not only for cutting and drilling tools but also can be applied as input needles, various roll wear parts and structural materials. In addition, it can be widely used in many fields, such as machinery, chemical industry, petroleum, metallurgy, electronics and defense industries.
Process flow
The main process flow includes powder milling formula according to application requirements → wet milling → mixing → crushing → drying → sieving → adding forming agent → re-drying → sieving to obtain a mixture → granulating → pressing → forming → low-pressure Sintering → Forming (blank) → Cylindrical grinding and fine grinding (the carbide blank does not have this process) → Detecting dimensions → packaging → warehousing.

Tungsten carbide rotary burr
The tungsten carbide rotary burr can be used to process cast iron, cast steel, carbon steel, alloy steel, stainless steel, hardened steel, copper and aluminum. Since the carbide rotary burr is hand-controlled on a high-speed rotation, the pressure and feed speed are determined to the service life and cutting effect of the tool.
Advantages
1. It can process iron, cast steel, carbon steel, alloy steel, stainless steel, copper, aluminum, etc and non-metals such as marble, jade, bone. Processing hardness can reach HRA ≥ 85.
2. Basically, it can replace a small grinding wheel and no dust pollution.
3. High production efficiency. The processing efficiency is more than ten times higher than the handmade file and is nearly ten times that of the small grinding wheel with the handle.
4. Good processing quality and high finish. It can be processed in various high-precision shape mold cavities.
5. Long service life. Durable is ten times higher than that of high-speed steel tools, which is more than 200 times higher than small grinding wheels.
6. Easy to use, safe and reliable.
7. Comprehensive processing costs can be decreased by several times.
Applications
1. Finishing various metal mold cavities such as shoe molds, etc.
2. Various metals and non-metallic process engraving, craft gift engraving.
3.Clean up the feed, burrs, weld of the casting, forging, welding in machine casting factories, shipyards, automotive plants, etc.
4.Chamfered rounds and trench processing, cleanup pipelines, finishing pipelines, and mechanical plants, repair shops, etc.
5.Decoration of the impeller flow path in the automobile engine factory.
Tungsten carbide Dies
The carbide dies have several tens of times longer service life than steel molds. The carbide mold has high hardness, high strength, corrosion resistance, high-temperature resistance and small expansion coefficient, generally composed with tungsten cobalt.
