Aluminium Bronze | C95400, C95500, C95800

Chemical Composition

The following table represents the typical chemical composition (by weight %) of Aluminium Bronze alloys. These grades are strengthened through the addition of aluminium, iron, and nickel, giving the alloys superior mechanical properties and corrosion resistance in marine and industrial environments.

Note: Minor variations in composition may occur depending on the manufacturing standard (ASTM B148, ASTM B150, BS 2874, or EN 1982). The addition of Nickel and Iron enhances strength and corrosion resistance, particularly in marine and high-load applications.

Mechanical, Physical & Fabrication Properties

Aluminium Bronze alloys combine the strength of steel with the corrosion resistance of copper. They are highly durable, offering excellent performance under mechanical stress, friction, and seawater exposure. The following table outlines the typical properties of commonly used Aluminium Bronze grades.

Note: The mechanical and physical values are typical and may vary slightly depending on section thickness, temper condition, and manufacturing process. Aluminium Bronzes are suitable for heavy-load applications, exhibiting excellent wear and galling resistance along with superior corrosion performance in marine and chemical environments.

Applications

Aluminium Bronze alloys are trusted for their combination of high strength, corrosion resistance, and durability in demanding environments. Their performance under stress, abrasion, and seawater exposure makes them ideal for both marine and industrial use.

• Marine hardware, propeller shafts, pump impellers, and deck fittings
• Valve bodies, seats, and stems for seawater and chemical systems
• Bushings, bearings, wear plates, and heavy-duty sliding components
• Pump and compressor components operating under high pressure
• Shipbuilding and offshore oil & gas structures exposed to seawater
• Landing gear components and aerospace fittings requiring strength and corrosion resistance
• Heat exchanger and condenser plates in corrosive or high-temperature environments
• Non-sparking tools and mechanical components for hazardous environments
• Architectural applications requiring bronze aesthetics and structural durability

Navkar Metal Syndicate supplies Aluminium Bronze in precision-engineered bars, plates, flanges, and fittings, ensuring each component meets global standards for performance, reliability, and corrosion resistance in harsh operating conditions.

Standards & International Equivalents:

The aluminium bronze grades below are commonly referenced across global standards. Exact equivalence can vary by product form (cast, continuous cast, centrifugal cast, wrought) and by the required mechanical properties. Always confirm against the project MDS / PO and relevant standard edition.

Notes: (1) EN 1982 uses both chemical symbols and casting codes (e.g., CC333G) — supplier datasheets often show either. (2) “Approx.” indicates commonly accepted cross-references by chemistry and typical properties; verify dimensional/strength class by form (sand cast, centrifugal, continuous cast) before substitution.

Common Names & International Identifiers

Aluminium Bronze alloys are identified globally under multiple designations depending on the standard, chemical composition, and intended service conditions. The following table lists commonly used trade names and international identifiers for the major grades supplied by Navkar Metal Syndicate.

Note: The above identifiers reflect equivalent designations based on composition and functional similarity across major global standards. Alloy selection should be verified based on service environment, mechanical requirement, and fabrication process.

Common Product Forms & Dimensions

C95400, C95500, and C95800 Aluminium Bronze alloys are among the most widely used copper-based alloys for marine, engineering, and heavy-duty industrial applications. They are typically manufactured by continuous casting or centrifugal casting methods, ensuring consistent properties, fine grain structure, and excellent machinability.

Available Forms

• Bars: Round, square, hexagonal (hex), and flat sections.
• Tubes / Hollow Bars: Continuous and centrifugal cast hollows for machining bushings, bearings, and sleeves.
• Plates: Wear plates, liners, and mill stock sheets available in multiple thicknesses.
• Other Forms: Billets, ingots, wire, forgings, profiles, and structural shapes.
