高比重合金是一种以钨为基(其含量为90～99%),并加有少量Cu、Ni、Fe、Co、Mo、Cr等元素组成的合金。这类合金具有一系列十分优异的工程性能,例如: 1.比重很高:一般比重为16.5～18.75克/厘米~3。即相当于钢比重的两倍以上。由于以其比重高为重要特征,并为一般合金所不及,故这类合金便有重合金或高比重合金之称。2.强度很高:抗拉强度为70～100公斤/毫米~2。即与优质中碳钢的抗拉强度相当,为黄铜或铸铁的两倍以上。
The high specific gravity alloy is a kind of tungsten based (its content is 90-99%), with a small amount of Cu, Ni, Fe, Co, Mo, Cr and other elements. Such alloy has a series of very good engineering performance, for example: 1. The proportion is very high: The general proportion is 16.5 ~ 18.75 g / cm ~ 3. That is equivalent to more than twice the proportion of steel. Because of its high proportion as an important feature, and generally less than the alloy, so there will be heavy alloys such alloys or high proportion of alloy said. 2. High strength: Tensile strength of 70 to 100 kg / mm ~ 2. That is, with the tensile strength of high-quality medium-carbon steel, brass or cast iron more than twice.
