CuAl9Ni3Fe2Mn2, CW304G, ASTM B148/B505, ASTM B271, BS 1400, DIN 17662, DIN 1705
CuAl9Ni3Fe2 is a specific copper alloy with a composition primarily consisting of copper, aluminum, nickel, and iron. This alloy is commonly referred to as aluminum bronze with added nickel and iron for improved mechanical properties and corrosion resistance. The norms and standards for CuAl9Ni3Fe2 typically include various international and regional standards that regulate its properties, composition, and applications.
Specifications
-
High Strength: The combination of aluminum, nickel, and iron results in a strong, durable material, suitable for heavy-duty applications.
-
Excellent Corrosion Resistance: Particularly in marine and industrial environments, this alloy resists corrosion due to the protective oxide layer formed by aluminum and the stabilizing effects of nickel and iron.
-
Wear Resistance: The alloy is resistant to wear and abrasion, making it ideal for components exposed to friction.
-
Good Castability: CuAl9Ni3Fe2 is suitable for casting, and its excellent mechanical properties are maintained even in complex shapes.
-
Thermal and Electrical Conductivity: While its conductivity is lower than pure copper, it is adequate for specific applications, especially those requiring mechanical performance over electrical conductivity.
Applications
-
Marine Industry: Components like propellers, shafts, and pump parts exposed to seawater.
-
Industrial Equipment: Bearings, bushings, and gears used in high-wear environments.
-
Aerospace and Automotive: Parts requiring strength and resistance to harsh conditions, such as gears and high-load components.
