Nilo Alloy Bars and Rods are mainly made of nickel and iron, with specific additions of cobalt and other alloying elements to achieve the required stability and strength. This composition provides excellent control over thermal expansion and remarkable resistance to corrosion. Mechanically, Nilo alloys deliver high tensile strength, good elasticity, and superior dimensional stability at high temperatures. Their low thermal expansion is especially useful in applications that need precision under thermal stress. The mix of strength, toughness, and reliability ensures consistent performance in demanding engineering and industrial settings.
