Special Bronze – Materials and norms

CuNi10Fe1.6Mn is one of the most corrosion-resistant copper alloys, so it is used in shipbuilding, desalination plants, cladding, pipes, flanges, heat exchangers, boilers, evaporators or fire extinguishing systems.

CuNi15Zn21 is also referred to as alpaca, white brass, nickel brass, pakfong or new silver. In engineering, it can be used for water pipes or heating spirals. Alpaca is known mainly for door handles and windows, jewelry, musical instruments or dishes.

CuNi30 is characterized by excellent corrosion resistance in seawater and high strength. It is thus used in shipbuilding, on pipes exposed to saline water, heat exchangers, condensers, oil coolers, desalination plants, etc.

CuSn9P is comparable to CuSn8 (CW453K) and CuSn8P. It is therefore a strong material with high corrosion resistance. It is used when confronting problems with friction in rings and bushings. Thanks to its sliding properties, it is particularly suitable for bearing and guide bushings for pumps or machining tools. It is also used in production of springs, bolts, couplings, connectors, fuses, paper net warps, art objects, etc.

CuSn10P exhibits high tensile strength and resistance to fatigue or corrosion. It is suitable for heavy duty components (e.g. working at high speeds) such as rings, sleeves, segments, valve guides, bearings, etc. but enough lubrication has to be provided.
