Special Bronze

Special bronzes include phosphorus (CuSn9P and CuSn10P), nickel, berylium or mangenese bronzes.

We supply bronze in the form of bars (round, flat, square, hexagonal, hollow), tubes or sheets

Below you will find a selection of the most common material grades we work with. Notice for the EN 1982 standard: We usually use the prefix CC (e.g., CC492K), which denotes castings, but you may encounter the prefix CB (e.g., CB492K) elsewhere, indicating ingots. The prefix CW denotes wrought alloys.

If you are interested in another grade or alloy, do not hesitate to contact us.

CuNi10Fe1,6Mn

CW352H

C70600

CuNi10Fe1,6Mn

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.

CuNi15Zn22

CuNi15Zn21

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

CW354H

2.0882

C71580

CuNi30

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

CW459K

CuSn9P

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.

Chemical composition

Cu	P	Pb	Sn	Zn	Fe

CuSn10P

CW451K

C51000

CuSn10P

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.
