At ICAST ALLOYS LLP, we specialize in the precision manufacturing of Aluminium Bronze Investment Castings. Leveraging our ISO 9001:2015 and PED 2014/68/EU certified facilities in Rajkot, India, we provide high-integrity components designed to withstand the most aggressive industrial environments.
Our investment casting (lost-wax) process ensures that every Aluminium Bronze part meets the highest standards of dimensional accuracy and metallurgical purity, serving critical sectors like Marine, Defense, Oil & Gas, and Aerospace.
Aluminium Bronze is a copper-based alloy where aluminium is the primary alloying element. Unlike traditional bronzes, this alloy offers a unique combination of high tensile strength (comparable to medium-carbon steel) and unparalleled corrosion resistance. By using the investment casting process, ICAST ALLOYS LLP can produce intricate, near-net-shape components that require minimal post-machining.

Due to its biostatic properties (prevents marine growth) and non-sparking nature, our Aluminium Bronze castings are essential for:
Marine & Offshore: Propellers, pump impellers, hull fittings, and underwater fasteners.
Oil & Gas: Non-sparking safety tools, valve bodies, and components for hazardous zones.
Industrial Pumps & Valves: Corrosion-resistant housings and wear rings for chemical processing.
Defense & Aerospace: High-strength structural brackets and landing gear components.
Heavy Machinery: Bushings, bearings, and worm gears requiring high load-bearing capacity.
Exceptional Corrosion Resistance: Naturally forms a protective aluminium oxide film that self-heals if damaged, especially in chloride-rich and acidic environments.
High Strength-to-Weight Ratio: Offers the mechanical properties of steel while maintaining the non-ferrous benefits of copper alloys.
Biostatic Properties: Naturally inhibits the growth of algae, barnacles, and other marine organisms.
Non-Sparking & Non-Magnetic: Ideal for use in explosive atmospheres (mines, oil rigs) and sensitive instrumentation.
Superior Surface Finish: The investment casting process provides a smooth finish (average 125 micro-inch) and high dimensional precision.
Higher Initial Material Cost: Copper-based alloys are generally more expensive than carbon steel or standard aluminium.
Complexity in Casting: Requires strict temperature control and expert handling to avoid oxide inclusions during the pour.
Size Limitations: While ideal for intricate parts, very large/bulky components may be better suited for sand casting
Engineering Expertise: Our metallurgists assist in selecting the optimal alloy grade for your specific environmental challenges
Integrated Solutions: From Casting Simulation to In-house CNC Machining, we provide a complete "ready-to-assemble" component
Quality Assurance: We utilize advanced testing (Spectrometer, Hardness, Microstructure) to ensure every batch complies with international standards
