We are one of the leading manufacturers and exporters of Silicon Bronze Castings and Bronze Cold Formed Components from India. We have been supplying high-performance Silicon Bronze Fittings, Machined Parts, and custom-engineered solutions to the world market for many decades. Our foundry is equipped to handle small to medium batches with full flexibility, quick turnaround, and strict adherence to international quality standards. With more than 30 years of global exposure, we have developed advanced capabilities in casting, cold forming, and precision machining of Silicon Bronze alloys. Our reputation is built on technical expertise, personalized customer support, and the ability to deliver complex parts across sectors such as marine, electrical, aerospace, oil & gas, and general engineering. . Our range of Phosphor Bronze casting, Phosphor Bronze Fittings , Phosphor Bronze machined parts and components is accepted quite well across the industries of the world.
Silicon Bronze Casting Silicon Bronze Castings are produced using premium Copper-Silicon alloys conforming to ASTM B584 (e.g., C87500, C87800), BS 1400, and EN 1982 standards. We employ both sand casting and investment casting processes depending on the geometry and required surface finish. Our process integrates shell molding, precise gating systems, and strict control over pouring temperature to ensure porosity-free, homogeneous castings.
Silicon Bronze Parts We supply a wide variety of Silicon Bronze Parts including bushings, terminal connectors, impellers, marine hardware, valve bodies, and decorative components. These parts are produced with tight dimensional tolerances, excellent corrosion resistance, and consistent surface integrity. Our in-house CAD/CAM team helps customers with DFM (Design for Manufacturability) optimization.
Silicon Bronze Fittings Our range of Silicon Bronze Fittings includes threaded adapters, elbows, tees, unions, flanges, and couplings used in plumbing, marine, and high-corrosion environments. These are manufactured as per ANSI B16.15, ASME, and ISO specifications, available in sizes from 1/8″ to 4″ NPT/BSPT.
Silicon Bronze Casting Foundry Our state-of-the-art Silicon Bronze Casting Foundry in India is equipped with multiple casting methods to suit diverse part geometries and mechanical requirements. We specialize in:
- Silicon Bronze Sand Casting for robust and economical production of large and medium-sized components.
- Silicon Bronze Investment Casting (lost wax process) for highly precise, thin-walled, and intricate parts.
- Silicon Bronze Shell Molding / Resin Sand Casting for complex core sections with excellent surface finish.
- Silicon Bronze Centrifugal Casting for symmetrical parts such as bushings and sleeves, ensuring a dense and defect-free microstructure. All castings undergo rigorous quality checks including chemical analysis, NDT testing, and visual/dimensional inspection before dispatch.
Silicon Bronze Cold Forming Using grades like C65500 and C65100 conforming to ASTM B124, we cold-form precision parts like bolts, lugs, and inserts. Our high-speed presses and annealing furnaces ensure crack-free cold workability. We also provide thread rolling and surface finishing options.
Silicon Bronze Machined Parts Our CNC turning and VMC machining centers handle tight-tolerance Silicon Bronze Machined Parts like electrical lugs, marine shaft sleeves, and hydraulic fittings. We offer CNC tolerances up to ±0.01 mm and can supply parts in mill finish, polished, or nickel-plated as per customer requirements.
Silicon Bronze Cold Forged Fasteners Our Silicon Bronze Cold Forged Fasteners are manufactured using high-strength, corrosion-resistant alloys such as C65500 and C66300. These fasteners are ideal for applications in marine, electrical, architectural, and chemical processing industries due to their excellent resistance to seawater and atmospheric corrosion. We produce a full range of fasteners—hex bolts, machine screws, threaded rods, studs, and custom per-print geometries—using multi-station cold heading and thread rolling equipment. Each part is processed with post-forming stress relief and is available in natural, polished, or plated finishes. All fasteners conform to ASTM, DIN, ISO, or BS specifications and are quality checked for tensile, shear, and dimensional conformity.
