Ashraf Nickel Alloys, based in Riyadh, Saudi Arabia, stands out as a top manufacturer and supplier of Invar 42 Bars. These high-quality nickel-iron alloy bars are specifically designed for applications that demand minimal thermal expansion. Renowned for their precision, dimensional stability, and durability, the company caters to various industries, including aerospace, precision instruments, electronics, and scientific equipment manufacturing. Ashraf Nickel Alloys provides Invar 42 Bars in a range of sizes and specifications to fulfill diverse industrial needs. Thanks to advanced manufacturing techniques and rigorous quality control, each bar is crafted to ensure reliable performance, a long service life, and compliance with international standards.
Invar 42 Bars are primarily made up of nickel (about 42%) and iron (the remainder), with small amounts of other elements added to boost stability. This unique composition gives the bars an incredibly low coefficient of thermal expansion, allowing them to keep their dimensions stable across a wide temperature range. On the mechanical side, Invar 42 Bars offer moderate tensile strength, excellent toughness, and good machinability, making them perfect for applications where thermal stability and precision are paramount.
