Made up primarily of tungsten carbide (WC) particles bound with a metal binder, such as cobalt, cemented carbide integrates the stamina of tungsten with the sturdiness of various other steels. The composition of cemented carbides can be tailored to fit particular applications, leading to the production of ranges like YG20, https://www.webwiki.it/www.wolframcarbide.com/ja/%e8%a3%bd%e5%93%81-2/%e8%b6%85%e7%a1%ac%e5%90%88%e9%87%91%e4%b8%b8%e6%a3%92/
