Aluminium 7075 T6 / T651 Blocks

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

At Solitaire Steel & Engineering LLP, Mumbai, India, we are one of the most trusted manufacturers and exporters of Aluminium 7075 T6 / T651 Blocks, engineered for applications where high strength, low weight, and precision are critical. These blocks are produced to ASTM B209 / B211 / B221 / EN 485-2 / IS 737 standards and widely used across aerospace, defence, automotive, and mould-making industries.

Aluminium 7075 is a zinc-based aluminium alloy delivering the highest strength-to-weight ratio among commercial aluminium grades. In T6 temper, it offers outstanding mechanical strength; in T651, it is stress-relieved by stretching, providing enhanced dimensional stability for CNC machining and die manufacturing.
