탄화물과 텅스텐강의 차이
1. Tungsten steel: the finished products contain about 18% tungsten alloy steel, tungsten steel belongs to the hard alloy, also known as tungsten titanium alloy. The hardness is 10K, second only to diamond. Because of this, tungsten steel commodity (see more tungsten steel watch), with the characteristics of not easy to be worn. It is often used on lathe tools, percussion drill bits, glass cutting head, and ceramic tile cutting knife.
2. Carbide: to cemented carbide powder metallurgy field and metal-ceramic metal carbide (WC, TaC TiC, NBC, etc.) or metal oxide (such as Al2O3, ZrO2, etc) as the primary ingredients, in just the right amount of metal powder (Co, Cr, Mo, Ni, Fe) made by powder metallurgy method, has the qualities of some metal ceramics. Cobalt (Co) is used to bond the alloy. During sintering, it encloses tungsten carbide (WC) powder and binds it tightly together. General content: 3%--30% tungsten carbide (WC) is the primary component of some metallic properties of this carbide or cermet, 70%-- 97% (component ratio) is widely used for wear resistance, high-temperature resistance, corrosion resistance, harsh working conditions of parts or tool, tool head. Tungsten steel is attributed to the hard alloy, but the hard alloy is tungsten steel is different, nowadays the customer of Taiwan and southeast Asia country likes to use tungsten steel this word, if talk with them carefully thorough, can discover, the majority still is to point to hard alloy.
텅스텐강과 경질합금의 차이점은 고속강 또는 공구강이라고도 불리는 텅스텐강은 연강기술로 강철에서 텅스텐과 철을 녹여 만든 것으로 고속강 또는 공구강이라고도 하는데, 그 텅스텐 함량은 보통 15~25%이다.경질합금은 텅스텐을 탄화하고 코발트나 다른 접착금속과 분말야금기술을 통해 소결한 것으로, 텅스텐 함량은 보통 80% 이상이다.
브리핑에 따르면, HRC65보다 경도가 높은 것은 합금을 경질 합금이라고 할 수 있는 한 텅스텐 강철은 HRC85에서 92 사이의 경도가 있는 경질 합금으로, 흔히 비표기 도구, 양구를 만드는 데 사용된다.
