锡青铜是铸造收缩率 小的有色金属合金，用来生产形状复杂、轮廓清晰、气密性要求不高的铸件。锡青铜在大气、海水、淡水和蒸汽中十分耐蚀，广泛用于蒸汽锅炉和海船零件。含磷锡青铜具有良好的力学性能，可用作高精密工作母机的耐磨零件和弹性零件。含铅锡青铜常用作耐磨零件和滑动轴承。含锌锡青铜可作高气密性铸件。

锡青铜在电气、电子工业中应用 广、用量 ，占总消费量一半以上。用于各种电缆和导线，电机和变压器的这种，开关以及印刷线路板　在机械和运输车辆制造中，用于制造工业阀门和配件、仪表、滑动轴承、模具、热交换器和泵等。在化学工业中广泛应用于制造真空器、蒸馏锅、酿造锅等。在建筑工业中，用做各种管道、管道配件、装饰器件等。
