CC211A Silicon Bronze Casting
CC211A Silicon Bronze Casting | BS EN 1982 Silicon Bronze | C87600 Equivalent
CC211A Silicon Bronze casting, designated under BS EN 1982 as the standard European silicon bronze casting alloy, is equivalent to UNS C87600 (USA), DIN CuSi3 (Germany), IS 318 Gr.SiB2 (India), and ISO CuSi3. Electrical Accessories India manufactures CC211A silicon bronze castings using sand casting, investment casting, centrifugal casting, green sand casting, and permanent mold casting for European, UK, Australian, and international customers requiring BS EN 1982 certification.
CC211A contains 3.0-5.0% silicon and 0.8-1.5% manganese in a copper matrix, delivering 430 MPa minimum tensile strength, 18% elongation, and excellent weldability with ERCuSi-A filler wire. The BS EN 1982 standard covers ingots and castings for CC211A silicon bronze, making it the preferred designation for UK and European purchasers specifying silicon bronze castings to EN standards.

CC211A Silicon Bronze Casting Processes
CC211A Silicon Bronze Sand Casting
CC211A Silicon Bronze Sand Casting (BS EN 1982) produces large and complex components using furan resin-bonded sand moulds. Component weights from 0.05 to 200+ kg. Tolerances CT7-CT9. Surface finish Ra 6.3-12.5 um. Lead times 1-2 weeks. All CC211A sand castings supplied with EN 10204 3.1 mill certificates confirming chemical analysis to BS EN 1982 limits. Ideal for European and UK purchasers requiring BS EN certified silicon bronze sand castings for marine, chemical plant, and architectural applications.
CC211A Silicon Bronze Centrifugal Casting
CC211A Silicon Bronze Centrifugal Casting produces dense hollow cylindrical components to BS EN 1982 CC211A specification. Tolerances CT5-CT6. Particularly suitable for bearing bushings, pipe flanges, valve seat rings, and cylindrical fittings for European marine and chemical plant applications specified to BS EN 1982.
CC211A Silicon Bronze Investment Casting
CC211A Silicon Bronze Investment Casting (lost-wax process) achieves CT4-CT5 tolerances and Ra 1.6-3.2 um surface finish to BS EN 1982.
