B65 Aluminium - High-Performance Alloy for Defense and Military Applications
B65 aluminium, also known as Woodford B65, is a premium wrought aluminium alloy widely used in defense and military industries. Its excellent strength-to-weight ratio, durability, and corrosion resistance make it ideal for manufacturing armored vehicles, weapon components, and defense systems. Russian Metals supplies certified B65 aluminium with reliable sourcing, ensuring quality and compliance for critical applications.
Overview of B65 Aluminium
B65 Aluminium is a high-strength aluminum-copper-magnesium alloy (Al-Cu-Mg system) engineered for aerospace, automotive, and structural engineering applications that demand superior mechanical strength, fatigue resistance, and thermal stability.
Developed as a Russian equivalent of the 2024 aluminium alloy, B65 Aluminium is renowned for its excellent strength-to-weight ratio and outstanding fatigue performance. It is a heat-treatable alloy, most commonly used in T6 and T8 tempers, offering a reliable balance of strength, machinability, and performance under stress.
- • High corrosion and seawater resistance
- • Strong yet lightweight (ideal for load-bearing components)
- • Excellent weldability and formability
- • Retains strength under moderate temperatures
