Starc Metals stands out as a top-notch manufacturer and supplier of Nilo Alloy 48 Bars and Rods right here in Canberra, Australia. We take pride in offering high-quality nickel-iron alloy products that are crafted for precision and stability. Our Nilo Alloy 48, also known as Alloy 48 or Invar 48, is specially engineered for controlled expansion, making it a perfect match for soft glass and ceramics. It boasts impressive dimensional stability across a broad temperature range, which makes it an excellent choice for electronic, electrical, and instrumentation applications. At Starc Metals, we are committed to delivering exceptional quality, a fine surface finish, and precise composition control, ensuring our products meet the rigorous standards of advanced engineering industries.
When it comes to the composition of our Nilo Alloy 48 Bars and Rods, you’ll find about 48% nickel and 52% iron, along with trace amounts of carbon, manganese, and silicon. This unique balance of nickel and iron results in a low coefficient of thermal expansion, especially between –50°C and +200°C. On the mechanical side, it offers a tensile strength of around 480 MPa, a yield strength of about 275 MPa, and remarkable ductility and toughness. The alloy maintains its magnetic stability and structural integrity even under varying thermal conditions, making it perfect for applications that require precision and thermal compatibility.
