Aiman Metals distributes Nilo Alloy 36 Bars and Rods in Kuala Lumpur, Malaysia, renowned for its very low coefficient of thermal expansion. Also known as Invar 36, nickel-iron alloy is essential in applications where dimensional stability at a wide range of temperatures is needed. Aiman Metals offers precision-ground bars according to ASTM F1684 and other engineering standards. Nilo 36 is used for tooling, aerospace parts, gages and measuring instruments, and cryogenic equipment where stability and accuracy are essential.
Nilo 36 contains ~36% nickel and balance iron. It has a tensile strength of ~480–550 MPa and retains its ultra-low expansion rate of ~1.2 × 10⁻⁶ /°C from cryogenic temperatures to ~250°C. The alloy is reasonably machinable, magnetic, and can be welded and cold-worked as required.
