As the important accessories of seawater pipes system, seawater pump and valve usually made of tin bronze and silicon brass were not able to meet the high reliability requirement for seawater pipes, because they were liable to serious electric coupling corrosion as they were coupled with the currently popularized B10 alloy in sea water.
海水泵阀等附件是海水管系的重要部件 ,国内常用锡青铜、硅黄铜制造 ,与目前推广使用的B10合金在海水中偶合时 ,电偶腐蚀较重 ,不能满足海水管系对高可靠性的要求。
