Machining Aluminium Blocks

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

At Solitaire Steel & Engineering LLP, Mumbai, India, we manufacture and export precision-engineered Machining Aluminium Blocks specifically designed for high-speed CNC, milling, and die-making operations. Our aluminium blocks are made from premium alloys like 6061, 6082, and 7075, available in T6 / T651 tempers, ensuring excellent machinability, dimensional stability, and surface finish.

Complying with ASTM B209 / B211 / EN 485-2 / IS 737, our machining blocks undergo rigorous ultrasonic (UT), hardness, and micro-structural tests to ensure flawless internal integrity. These properties make them ideal for tooling, mould-making, aerospace components, jigs, fixtures, and prototype fabrication where precision and repeatability are paramount.
