Cemented Carbide Ball
Cemented carbide balls are made of high-hardness, refractory metal carbides (WC, TiC) micron powder as the main component, with cobalt (Co), nickel (Ni), and molybdenum (Mo) as binders, in a vacuum furnace or The powder metallurgy products sintered in the hydrogen reduction furnace, the common hard alloys are YG, YN series.
Cemented carbide balls mainly include rough balls, fine grinding balls, punching balls, bearing balls, valve balls, non-magnetic balls, through-hole balls, metering balls, color-scraping balls, pen balls, etc.
Commonly used grades are: YG6. YG6x, YG8, YG13, YG20, YN6, YN9, .YN12
Cemented carbide balls have high hardness, wear resistance, corrosion resistance, bending resistance, and harsh environment, which can replace steel ball products. Hard alloy ball hardness ≥90.5, density = 14.9g/cm3.
Cemented carbide balls have a wide range of applications, such as: precision parts punching and drawing, bearings, instruments, meters, pen-making, spraying machines, water pumps, mechanical accessories, sealing valves, brake pumps, punching holes, oil fields, laboratories, Hardness measuring instrument, fishing gear, counterweight, decoration and other high-end industries
The production process of cemented carbide balls is similar to other cemented carbide products, mainly including powder making → formula according to application requirements → wet grinding → mixing → crushing → drying → sieving → adding forming agent → re-drying → sieving Prepare mixture → granulation → cold isostatic pressing → forming (blank) → sintering → forming (finished product) → packaging → warehousing.
