EN Standards

·                     EN 1982:2008: Copper and copper alloys – Ingots and castings.

o                                           This standard covers various copper alloys, including bronzes, used in casting applications.

o                                           Examples: CuSn10 (Tin Bronze), CuAl10Ni5Fe4 (Aluminum Bronze).

Common Bronze Alloys for Bearings

1.                 Tin Bronzes (e.g., CDA 932, CDA 937)

o                                           High wear resistance and good machinability.

o                                           Often used in oil-impregnated bearings.

2.                 Aluminum Bronzes (e.g., CDA 954, CDA 955)

o                                           Excellent strength and corrosion resistance.

o                                           Suitable for heavy-duty applications.

3.                 Lead Bronzes (e.g., CDA 943, CDA 944)

o                                           High load capacity and good conformability.

o                                           Commonly used in automotive and industrial bearings.
