Tungsten carbide, commonly referred to as “carbide”, is a common material in shops. This tungsten and carbon compound has completely changed the world of metal cutting in the past few decades, increasing speed and feed rate and prolonging tool life. Tungsten carbide was first studied as a tool material in 1925. Later, Ge set up a special department to produce tungsten carbide cutting tools. In the late 1930s, Philip M. McKenna, the founder of Kennametal, found that adding titanium compounds to the mixture could make tools work better at higher speeds. This began to move towards today’s lightning cutting speed.<\/p>\n\n\n\n

“Cemented carbide”, the materials constituting tools and blades, are actually tungsten carbide particles along with other materials, which are cemented together with metal cobalt as binder.<\/p>\n\n\n\n

At this point, tungsten carbide is ready to be mixed into “grade powder”. In the tungsten carbide industry, people speak of grade rather than alloy, but they mean the same.<\/p>\n\n\n\n

Tungsten carbide enters a mixing vessel together with other components of this grade. Powdered cobalt metal will act as a “glue” to bond the materials together. Other materials such as titanium carbide, tantalum carbide and niobium carbide are added to improve the properties of the material during cutting. Without these additives, when cutting ferrous materials, tungsten carbide tools may react chemically between the tool and workpiece debris, leaving pits in the tool, especially in high-speed cutting.<\/p>\n\n\n\n

from raw material to final product Tungsten carbide, commonly referred to as “carbide”, is a common material in shops. This tungsten and carbon compound has completely changed the world of metal cutting in the past few decades, increasing speed and feed rate and prolonging tool life. Tungsten carbide was first studied as a tool material in 1925. Later, Ge set up a special department to produce tungsten carbide cutting tools. In the late 1930s, Philip M. McKenna, the founder of Kennametal, found that adding titanium compounds to the mixture could make tools work better at higher speeds. This began to move towards today’s lightning cutting speed. “Cemented carbide”, the materials constituting…<\/p>","protected":false},"author":2,"featured_media":21028,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[92],"tags":[],"jetpack_featured_media_url":"https:\/\/www.meetyoucarbide.com\/wp-content\/uploads\/2022\/03\/\u56fe\u724748484841.png","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts\/21040"}],"collection":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/comments?post=21040"}],"version-history":[{"count":0,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts\/21040\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/media\/21028"}],"wp:attachment":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/media?parent=21040"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/categories?post=21040"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/tags?post=21040"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
