AB1 (Aluminium Bronze) | BS1400 AB1 Alloy Castings

Conex Metals is a premier manufacturer and global exporter of AB1 Aluminium Bronze alloy castings, produced in compliance with British Standard BS1400: AB1. Our in-house foundry and machining facility produce precision-engineered AB1 components that deliver superior mechanical strength, wear resistance, and excellent corrosion protection — especially in marine and aggressive industrial environments.

AB1 Aluminium Bronze is a versatile engineering alloy that provides higher strength than standard bronzes and excellent resistance to corrosion in seawater, saline solutions, and chemical media. Its natural ability to withstand wear, shock loads, and cavitation makes AB1 a top choice for marine propeller components, pump bodies, valve parts, and structural mechanical systems. At Conex Metals, we produce AB1 parts for customers in marine engineering, offshore oil & gas, pumps & valves, mining, construction, and other demanding industries worldwide.

AB1 belongs to the family of aluminium bronze alloys, known for their:

• High strength-to-weight ratio
• Excellent resistance to corrosion (saltwater, chemicals)
• Superior wear and abrasion resistance
• Good machinability and dimensional stability
• Long service life under dynamic load conditions

Typical Chemical Composition:

We produce AB1 Aluminium Bronze castings using:

• Sand Casting — ideal for medium to large parts
• Centrifugal Casting — for sleeves, bushings, and rings
• Continuous Casting — for bars and stock material

After casting, we perform:

• CNC Turning and Milling
• Precision Boring
• Surface Grinding
• Finishing and Polishing

Our CNC machining centres ensure tight tolerances and repeatable quality — ideal for OEM and aftermarket industries.

AB1 is widely used for high-strength, corrosion-resistant components, such as:

• Marine Propeller Blades & Shafts
• Pump Casings, Impellers, and Rings
• Valve Bodies & Valve Seats
• Bearing Bushes & Wear Rings
• Hydraulic System Bushings
• Gears & Heavy Duty Mechanical Parts
• Oil & Gas Offshore Components
• Seawater Desalination Plants
