AB2 is a high-strength aluminum bronze alloy primarily used in marine, engineering, and heavy-duty industrial applications. It is known for its excellent corrosion resistance, wear resistance, and mechanical properties.


Composition of AB2 Aluminum Bronze

Typical chemical composition (as per BS 1400 AB2 or equivalent standards):

Element	Percentage (%)
Copper (Cu)	78-82
Aluminum (Al)	8.5-10.5
Nickel (Ni)	4-6
Iron (Fe)	4-5.5
Manganese (Mn)	0.5-1.5
Others (Si, Pb, Sn, Zn)	≤ 0.5

Key Properties of AB2 Ingots

✅ High Corrosion Resistance – Excellent resistance to seawater, making it ideal for marine applications.

✅ High Strength & Hardness – Superior mechanical properties compared to standard bronzes.

✅ Wear & Abrasion Resistance – Performs well in high-stress environments, including bearings and heavy machinery.

✅ Good Machinability – Can be cast and machined effectively.

✅ Non-Sparking & Non-Magnetic – Suitable for hazardous environments.

Applications:

✅ Marine Components – Propellers, pump casings, impellers, and ship parts

✅ Heavy Engineering – Bearings, gears, and valves

✅ Aerospace & Defense – Bushings, landing gear components

✅ Oil & Gas Industry – Wear-resistant parts in offshore rigs
