The silicon brass was used to fabricate the covers of cooler in order to satisfy the requirements of resistant sea water corrosion, high heat conductivity and enduring water pressure.

为了满足耐海水腐蚀、高导热率和承压能力要求，冷却器盖均采用硅黄铜制造。

Aluminum can improve the strength, hardness and brass corrosion resistance, but make plastic reduce, suitable for liner condensing tubes and other corrosion resistant parts.

铝能提高黄铜的强度﹑硬度和耐蚀性﹐但使塑性降低﹐适合作海轮冷凝管及其他耐蚀零件。
