Known for their precision-engineered materials, Anucha Metals caters to a wide array of industries with dependable products that adhere to international standards. Nilo Alloy 42 is a controlled expansion alloy, perfect for applications where maintaining a low and consistent thermal expansion rate is crucial. With a strong focus on innovation, customer service, and timely delivery, Anucha Metals has become a go-to partner for businesses in need of reliable high-performance alloys like Nilo Alloy 42.
Nilo Alloy 42, often referred to as Alloy 42, is made up of about 42% Nickel and 58% Iron. This alloy is known for its low and stable coefficient of thermal expansion, particularly in the temperature range of 20°C to 300°C. It boasts good strength, moderate ductility, and impressive thermal stability. Typically, it has a tensile strength of around 70 ksi (483 MPa) and a yield strength of about 45 ksi (310 MPa), with an elongation of 20–30%. Nilo Alloy 42 Bars and Rods are perfect for components that need precise performance in varying thermal conditions and under mechanical stress.
