這種合金具有較高的力學(xué)性能、減磨性能和耐蝕性，易切削加工，釬焊和焊接性能好，收縮系數(shù)小，無磁性?？捎镁€材火焰噴涂和電弧噴涂制備青銅襯套、軸套、抗磁元件等涂層。尺寸規(guī)格有Ф1.6mm、Ф2.3mm。具有較高的強度、耐蝕性和優(yōu)良的鑄造性能，長期以來廣泛應(yīng)用于各工業(yè)部門中。

(1)錫青銅以錫為主要合金元素的銅基合金稱錫青銅。工業(yè)中使用的錫青銅，錫含量大多在3%～14%之間。錫含量小于5%錫青銅適于冷加工使用;錫含量為5%～7%的錫青銅適于熱加工;錫含量大于10%的錫青銅適于鑄造。

錫青銅在造船、化工、機械、儀表等工業(yè)中廣泛應(yīng)用，主要用以制造軸承、軸套等耐磨零件和彈簧等彈性元件以及抗蝕、抗磁零件等。

鈹青銅以鈹作為主要合金組元的一種無錫青銅。含有1.7～2.5%鈹及少 量鎳、鉻、鈦等元素，經(jīng)過淬火時效處理后，強度 極限可達1250～1500MPa，接近中等強度鋼的水 平。在淬火狀態(tài)下塑性很好，可以加工成各種半成 品。鈹青銅具有很高的硬度、彈性極限、疲勞極限 和耐磨性，還具有良好的耐蝕性、導(dǎo)熱性和導(dǎo)電 性，受沖擊時不產(chǎn)生火花，廣泛用作重要的彈性元 件、耐磨零件和防爆工具等。
