简介:   高(gao)比(bi)(bi)重钨合(he)金(TungstenHeavy Alloy，简称WHA)产(chan)(chan)(chan)品(pin)通常由WNiFe或WNiCu或WNiCuFe通过粉(fen)末(mo)冶金工艺生产(chan)(chan)(chan)制(zhi)造(zao)而成。根据不(bu)同的产(chan)(chan)(chan)品(pin)用途和工作环境要求，高(gao)比(bi)(bi)重钨合(he)金产(chan)(chan)(chan)品(pin)钨含量通常分布为(wei)79%W~97%W，密(mi)度(du)范(fan)围(wei)为(wei)15.00g/cm~18.50g/cm。同时可以添加一些稀有(you)金属元(yuan)素（Co,Mo,Cr等(deng)）以提(ti)高(gao)产(chan)(chan)(chan)品(pin)部分性能，比(bi)(bi)如：硬度(du)(Hardness)，极限抗拉强(qiang)度(du)(Ultimate Tensile Strength)，屈服强(qiang)度(du)(Yield Strength)，延伸率(Elongation)等(deng)。高(gao)比(bi)(bi)重钨合(he)金是一类(lei)由80-98%分布于基(ji)体Ni-Fe-W固溶(rong)体中的两相(xiang)复合(he)材料。综合(he)了(le)钨金属高(gao)密(mi)度(du)、高(gao)强(qiang)度(du)和基(ji)体相(xiang)优良塑性，因而，它具有(you)一系列优异物理、化(hua)学、力学。
