Product description: 【Model】: YG6 Carbide Tungsten Steel Ball 【Material】: Carbide Tungsten Steel （YG6） 【Hardness】：HRA90 【Grade】: G10 【Diameter】: 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.2mm, 1.3mm, 1.35mm 1.5mm 【Application 】: Tungsten steel balls have a wide range of applications, such as precision bearings, instruments, meters, pen making, spraying machines, water pumps, mechanical parts, sealing valves, brake pumps, punching holes, oil fields, hydrochloric acid laboratories, hardness measuring instruments, fishing gear, counterweights, decoration, precision machining and other high-end industries. 【Characteristics】: Tungsten steel balls, commonly known as hard alloy balls or tungsten carbide balls, refer to balls and balls made of hard alloy materials. Hard alloy balls have high hardness, wear resistance, corrosion resistance, bending resistance, and can replace all steel ball products in harsh environments. 【Description】: Hard alloy balls, commonly known as tungsten steel balls, are powder metallurgy products made of hard alloy materials, mainly composed of micro sized carbide powders of high hardness refractory metals, cobalt (Co) or nickel (Ni), molybdenum (Mo) as binders, and sintered in vacuum furnaces or hydrogen reduction furnaces. Currently, common hard alloys include YG, YN, YT, YW series. Hard alloy balls have high hardness, wear resistance, corrosion resistance, bending resistance, and can replace all steel ball products in harsh environments. Hardness is 89 ° -93 °, density is 14.9g/cm3
