CW307G Rod – Nickel Aluminium Bronze for Critical Components
Nickel aluminium bronze CW307G (CuAl10Ni5Fe4) rods from Jintian are designed for demanding marine, aviation and industrial environments where high strength, wear resistance and seawater corrosion resistance are essential. Our CW307G rods are suitable both for direct machining and as forging stock for highly loaded parts.
💡 Why CW307G stands out
• Optimised alloy design: Aluminium, nickel and iron form a tough multiphase microstructure, giving high strength, good fatigue performance and excellent sliding behaviour.
• Proven seawater performance: A thin, adherent copper–aluminium oxide film provides durable protection in seawater and many industrial fluids, with very low general corrosion rates and high resistance to cavitation and erosion.
• Non-sparking: Aluminium bronzes, including CW307G, exhibit excellent non-sparking characteristics and are widely used for components in chemically hazardous and oil & gas environments.
⚙️ Key advantages of CW307G rods
1) High strength and hardness with useful toughness
2) Excellent resistance to corrosion, erosion and cavitation in seawater and many process media
3) Stable performance across a wide service temperature range; properties can be further tailored via quench-and-temper heat treatment where required
🏭 Typical applications (machined or forged from rod)
• Bearings & motion parts: plain and flanged bushes, spacers, self-lubricating bearing blanks and guide elements for aviation, oil & gas, mining and heavy machinery
• Valves & flow control: guides, stems, seat rings, bushings and small valve bodies for seawater and process lines
• Pumps: shafts, sleeves, wear rings, guide bushes, coupling elements and other rotating parts in seawater and chemical service
• Fasteners & fittings: high-strength bolts, nuts, studs and special threaded components for marine and offshore equipment
• Power transmission & mechanics: smaller gear blanks, worm wheels, cams and linkage parts where a combination of load capacity and corrosion resistance is required
🌍 Standards & equivalents
• EN: CW307G / CuAl10Ni5Fe4
• Typical international equivalents: ASTM C63000, BS CA104, GB QAI10-4-4, JIS C6301
♻️ Long-life, sustainable choice
The long service life and durability of CW307G components, combined with full recyclability, help reduce unplanned downtime, spare-part consumption and lifecycle cost in marine and industrial systems.
