研究了ＺＡ２７和ＺＡ２７Ｓｉ合金的高温力学性能和耐磨性能，并进行了阀门静压寿命试验。结果表明，锌铝合金特别是含硅的高铝锌合金具有优良的摩擦磨损性能，使用寿命长，是替代铜合金作阀门中螺母等耐磨件的理想材料。
The high temperature mechanical properties and wear resistance of ZA27 and ZA27Si alloys were studied and the valve static pressure life test was carried out. The results show that zinc-aluminum alloy, especially silicon-containing high-aluminum-zinc alloy, has excellent friction and wear properties and long service life. It is an ideal material to replace copper alloy for wear-resistant parts such as valve nuts.
