In-Depth Look at Our Aluminum Bronze Products
Aluminum Bronze Casting
Our Aluminum Bronze casting process is designed to yield components with exceptional mechanical properties, including high strength, excellent wear resistance, and outstanding corrosion resistance, particularly in seawater and acidic environments. We utilize both sand casting for larger, more intricate parts and investment casting for components requiring superior surface finish and tighter dimensional tolerances. Typical Aluminum Bronze cast parts include pump impellers, valves, gears, heavy-duty bearings, and bushings. We cast in a wide range of international material grades, including UNS C95400 (9% Aluminum Bronze), UNS C95500 (11% Aluminum Nickel Bronze), and the high-strength UNS C95900, conforming to standards like ASTM B148, BS 1400 AB-1/AB-2, and DIN EN 1982 CC333G.
Aluminum Bronze Casting Foundry
Our dedicated Aluminum Bronze casting foundry is the core of our operation, housing advanced machinery such as induction melting furnaces for precise alloy control, automated molding lines for consistency, and a fully equipped pattern shop for creating accurate wood, metal, or resin patterns. The foundry’s capabilities are complemented by a sophisticated laboratory for spectrochemical analysis to ensure melt chemistry and rigorous testing facilities for mechanical properties (tensile strength, yield strength, elongation) and NDT (Dye Penetrant Inspection). This integrated approach allows us to offer custom Aluminum Bronze castings with guaranteed performance metrics, making us a preferred Aluminum Bronze investment casting foundry for critical applications.
Aluminum Bronze Fittings
We manufacture a comprehensive range of marine-grade Aluminum Bronze fittings known for their superior resistance to biofouling and dezincification. Our product line includes Aluminum Bronze pipe fittings ( elbows, tees, couplings, flanges), Aluminum Bronze threaded rods, and custom forged Bronze fittings. These components are machined to exacting standards, often with threads cut to ANSI/ASME B1.20.1 or metric standards, ensuring perfect compatibility with global piping systems. They are indispensable in shipbuilding, offshore platforms, and desalination plants where failure is not an option. All our corrosion-resistant Bronze fittings are produced from certified materials and can be supplied with full traceability and material test certificates.
Aluminum Bronze Components
Beyond standard fittings, we excel in producing complex Aluminum Bronze components that are the heart of heavy machinery. These include non-sparking Aluminum Bronze tools for hazardous environments in oil and gas, wear plates for mining equipment, sleeves and thrust washers for high-load applications, and valve stems and seats. The combination of high yield strength and low magnetic permeability makes our components ideal for specialized applications in the defense and aerospace sectors. We work closely with clients to engineer components that optimize the unique properties of Aluminum Bronze, such as its excellent anti-galling characteristics against steel.
Aluminum Bronze Connectors
Our Aluminum Bronze connectors are engineered for reliability in critical fluid and power transfer systems. This category includes high-pressure hydraulic connectors, subsea electrical connectors, and custom lugs and terminals. These parts are often precision-machined from solid Aluminum Bronze bar stock or cast and finished to achieve flawless sealing surfaces and conductivity. The natural lubricity and corrosion resistance of Aluminum Bronze ensure long service life and reduced maintenance, even in the most challenging conditions, making our durable Bronze connectors a smart choice for engineering safety and efficiency into systems.

Manufacturing Process & Machinery
Our process begins with a client consultation to select the optimal alloy and manufacturing route. Sand casting is performed using chemically-bonded sand molds for stability, while investment casting uses wax patterns for precision. Melting is done in medium-frequency induction furnaces to ensure a homogeneous, high-quality melt. Post-casting, components are cleaned via shot blasting and often heat-treated (solution treated and tempered) to achieve desired mechanical properties. Our extensive CNC machining centers (both vertical and horizontal) and lathes perform the final precision machining to achieve tight tolerances and specific finishes.

Glossary of Terms
Investment Casting: A precision casting process using a wax pattern surrounded by a ceramic shell to produce parts with high dimensional accuracy and smooth surface finish.
Sand Casting: A versatile casting process where a sand mold is formed around a pattern to create a cavity for molten metal.
Dezincification: A form of corrosion specific to Brass where zinc is leached out, leaving a porous copper structure. Aluminum Bronze is highly resistant to this.
Non-Sparking Tool: A tool made from a material, like Aluminum Bronze or Beryllium Copper, that reduces the risk of generating sparks, essential in flammable environments.
NDT (Non-Destructive Testing): Methods like Dye Penetrant Inspection (DPI) or Radiography used to inspect the integrity of a casting without damaging it.
VCI Packaging: Volatile Corrosion Inhibitor packaging that releases a protective vapor to prevent rust during transit and storage.
