Home > Invar 42 Sheet and Plate
Welcome to Victor Nickelalloys, your trusted partner for premium metal solutions right here in Abuja. We specialize in supplying and manufacturing Invar 42, a unique alloy designed for exceptional stability. If your projects are challenged by temperature fluctuations that can cause ordinary materials to expand and contract, our Invar 42 sheet and plate offer the reliable, low-expansion performance needed to maintain precision and integrity in the most demanding environments, ensuring your work stands the test of time and temperature.
The remarkable stability of Invar 42 comes from its specific composition, which is a nickel-iron alloy containing approximately 36% nickel. This precise formulation is what grants it an extremely low coefficient of thermal expansion. In terms of mechanical properties, this material is not only stable but also strong, offering good tensile strength and yield strength. It is a malleable alloy that can be machined and welded with the right techniques, making it a versatile choice for engineers who need a material that won’t change shape with the heat.
