Aerospace Aluminium Blocks

Manufacturer, Supplier & Exporter – Solitaire Steel & Engineering LLP, Mumbai, India

At Solitaire Steel & Engineering LLP, Mumbai, India, we specialize in manufacturing and exporting Aerospace-Grade Aluminium Blocks engineered for exceptional strength, precision, and performance in high-stress environments. Our aerospace alloys — including 6061-T6 / T651, 6082-T651, and 7075-T651 — comply with ASTM B209 / B211 / AMS 4027 / EN 485-2 / IS 737 standards, meeting the stringent demands of aircraft and defence component manufacturing.

Designed for critical load-bearing structures, precision machined parts, and tooling applications, our aerospace aluminium blocks combine high tensile strength, fatigue resistance, and low density (2.7 g/cm³) — making them ideal for airframes, fuselage sections, wing fittings, jigs, fixtures, and ground support equipment. Each block is ultrasonically tested (UT), grain-refined, and heat-treated to ensure uniform mechanical integrity and machining stability.
