Here’s a professional website description you could use for Aerocom Metals Limited:
Aluminium Alloy 2219 – High Strength Aerospace Grade
Aerocom Metals Limited supplies premium-grade Aluminium Alloy 2219, a high-strength alloy renowned for its exceptional mechanical properties and excellent performance at elevated temperatures.
Developed primarily for the aerospace industry, 2219 aluminium is a heat-treatable alloy containing copper as its principal alloying element. It offers outstanding strength-to-weight ratio, superior fracture toughness, and excellent resistance to stress corrosion cracking. This makes it ideal for demanding structural applications, including fuel tanks, aircraft fuselages, and high-temperature components.
At Aerocom Metals, we supply 2219 aluminium sheet, plate, bar, and extrusion in a variety of tempers, all fully certified to aerospace standards. Our materials are precision-cut and quality-assured to meet exacting project requirements.
Key Properties:
- Excellent high-temperature strength and stability
- Good machinability and weldability (especially by inert gas methods)
- High fracture toughness and fatigue resistance
- Proven aerospace and defense-grade reliability
Typical Applications:
- Aerospace and spacecraft structures
- Cryogenic tanks and pressure vessels
- High-performance automotive components
- Military hardware
Available Tempers:
O (Annealed)
T31, T37, T4, T6, T62, T81
Mechanical Strength (Typical – T6 Condition):
Ultimate Tensile Strength: ~440 MPa
Yield Strength: ~370 MPa
Elongation: ~10%
Density: 2.84 g/cm³
Melting Range: 510–643°C
Aerocom Metals Limited supplies premium-grade Aluminium Alloy 2219, a high-strength alloy renowned for its exceptional mechanical properties and excellent performance at elevated temperatures.
Extrusion is a key process for forming 2219 alloy into bars, rods, profiles, and tubes. To optimize its properties, the extruded part undergoes further heat treatment, such as T6 or T8 tempering.
