DIN CuSi3 Silicon Bronze Casting
DIN CuSi3 Silicon Bronze Casting | DIN 1705 | C87600 Equivalent | CC211A
DIN CuSi3 Silicon Bronze casting (DIN 1705), the German DIN standard designation for standard silicon bronze, is equivalent to UNS C87600 (USA), BS EN 1982 CC211A (Europe/UK), IS 318 Gr.SiB2 (India), and ISO CuSi3. Electrical Accessories India manufactures DIN CuSi3 silicon bronze castings using sand casting, investment casting, centrifugal casting, green sand casting, and permanent mold casting for German, European, and international customers requiring DIN 1705 specification silicon bronze.
DIN CuSi3 contains 3.0-5.0% silicon and 0.8-1.5% manganese, delivering 430 MPa minimum tensile strength, 18% elongation, excellent weldability with ERCuSi-A filler, and superior corrosion resistance in seawater, industrial atmospheres, and chemical plant environments.
