DIPTI METAL INDUSTRIES
Dipti Metal Industries (A KMR Group Company) is the primary global destination for AMS 4031 Heavy Plates and AMS 4143 Custom Forgings. Aluminium 2219 is a high-performance Al-Cu alloy specifically engineered for launch vehicles and high-temperature aerospace structures. It offers exceptional weldability, high fracture toughness, and resistance to stress corrosion cracking. As a premier 2219 Aluminium Stockist, we supply material in T851, T87, and T6 tempers with 100% metallurgical traceability and EN 10204 3.1 certification.
Unlike other high-strength aluminium alloys, 2219 is easily weldable and maintains high mechanical properties at temperatures up to 315ยฐC (600ยฐF) and down to cryogenic levels.
