DIPTI METAL INDUSTRIES
Dipti Metal Industries (A KMR Group Company) is the definitive international leader for AMS 4027 Stockholding and AMS 4026 Supplying. Aluminium 6061 is the structural standard for aerospace engineering, offering high toughness, excellent corrosion resistance, and superior weldability. We house Indiaโs largest inventory of 6061-T6, T651, T4, and O-Annealed sheets and plates in Mumbai. Every material is sourced from world-class mills and supplied with original EN 10204 3.1 Mill Test Certificates and complete aerospace traceability.
Aluminium 6061 (Al-Mg-Si) is a precipitation-hardened alloy. While not as strong as the 2000 or 7000 series, it provides the best all-around balance of mechanical properties and corrosion resistance in marine and atmospheric environments.
