Elvis Nickel Alloys stands out as a top-notch manufacturer and supplier of Invar Bars right in Houston, USA. We specialize in crafting high-precision, low-expansion alloy bars that are perfect for critical industrial and scientific needs. Invar, a unique nickel-iron alloy, is celebrated for its incredibly low thermal expansion, making it a go-to choice for situations where maintaining dimensional stability is key. Our Invar bars are produced to meet rigorous international standards, ensuring they offer excellent machinability, weldability, and thermal consistency. We proudly supply these bars to various sectors, including aerospace, cryogenics, defense, electronics, and tooling, guaranteeing reliable performance in temperature-sensitive and precision-driven applications.
Invar Bars are made up of about 36% nickel and 64% iron, along with small amounts of carbon, manganese, and silicon. This distinctive nickel-iron alloy boasts a very low coefficient of thermal expansion (around 1.3 × 10⁻⁶/°C), which helps maintain dimensional stability across a wide range of temperatures. With tensile strength ranging from 490 to 620 MPa, Invar bars also offer good toughness and exceptional stability at both cryogenic and ambient temperatures. They are easy to machine and retain their structural integrity under precise tolerances, making them perfect for components that need to stay dimensionally accurate, even with thermal fluctuations.
