YG6, YG8 and YG15 are all tungsten-cobalt cemented carbides with hardness up to 89.5HRA and high strength, impact resistance, toughness and wear resistance. They are commonly used materials in the tool industry. Common sizes are round bar, sheet, plate, strip, tube, ring and so on. The commonly used brands are: YG3X, YG3, YG6, YG8, YG12, YL10.2, YL60, YG15, YG20, YG25, V10, V20, V40, Z01, Z10, Z30, etc
Brand number interpretation method:
The brand is made up of "YG" and "Y" representing the pinyin initials of hard alloy,
"G" stands for cobalt Pinyin initial.
Chemical composition of YG6: tungsten W:94%, Co:6%
YG8 chemical composition: tungsten W:92%, cobalt Co:8%
Chemical composition of YG15: tungsten W:85%, cobalt Co:15%
