主要特性 Main features |
|
QSn4-3 |
为含锌的锡青铜，耐磨性和弹性高，抗磁性良好，能很好地承受热态或压力加工;在硬态下，可切削性好，易焊接和钎焊，在大气，淡水和海水中耐蚀性 Tin-bronze containing zinc feature high wearability,elasticity and diamagentism;it can be processed status,it boasts high machiability,easy for welding and brazeweiding;high corrosion resistance under atmosphere,fresh water.seawater. |
|
制作弹簧(扁弹簧、圆弹簧)及其它弹性元件，化工设备上的耐蚀零件以及耐磨零件(如衬套、圆盘、轴承等)和抗磁零件造纸工业用的刮刀 It can be used to make spring(flat spring,round spring)and other elastic component,anti-corrosive and wear-resistant component of chemicat equipment(such as bushing,round plate,bearing),and anti-magnetic scraperin paper-making industry. | |
|
QSn4-4-2.5 QSn4-4-4 |
为添有锌、铅合金元素的锡青铜，有高的减摩性和良好的可切削性，易于焊接和钎焊，在大气、水中具有良好的耐蚀性，只能在冷态下进行压力加工，因含铅热加工时易引起热脆 Tin-bronze containing zinc and aluminum feature high machiability and frictionreduction property;easy for welding and braze welding;high corrosion resistanceunderfrdsh water:it can only be processed under pressuer in cold status:it containszinc soitis liable to become brittle under heat processing. |
