Aiman Metals provides Nilo Alloy 42 Bars and Rods in Kuala Lumpur, Malaysia, providing superior dimensional stability for electronic and sealing uses. Nilo Alloy 42 is a nickel-iron alloy with 42% nickel content and is designed to have the same thermal expansion as specific types of glass and ceramics. Aiman Metals provides Nilo 42 rods in various bar sizes, machined and annealed for precision use. It finds applications in hermetically sealing, having low thermal mismatch, and maintaining reliability of performance over temperature cycles.
Nilo 42 consists of ~42% nickel and remainder iron. The tensile strength is around 450–520 MPa, and it has a low coefficient of thermal expansion between room temperature and around 300°C. It is magnetic when in an annealed state and also maintains good ductility, machinability, and weldability for precision components.
