?Cu-OF C10200銅合金斷后伸長率

以錫為主要合金元素的青銅。含錫量一般在3～14%之間，主要用于制作彈性元件和耐磨零件。變形錫青銅的含錫量不超過 8%，有時還添加磷、鉛、鋅等元素。磷是良好的脫氧劑，還能改善流動性和耐磨性。錫青銅中加鉛可改善可切削性和耐磨性，加鋅可改善鑄造性能。這種合金具有較高的力學性能、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。
