Based in Amman, Jordan, Sabra Metals has built a solid reputation as a reliable manufacturer and supplier of high-quality Invar 36 Bars and Rods. These products are perfect for precision applications that demand outstanding dimensional stability. Made from a nickel–iron alloy known for its extremely low thermal expansion, Invar 36 is particularly suited for environments where temperatures fluctuate. Sabra Metals takes pride in maintaining strict oversight of chemical composition, processing, and dimensional accuracy to adhere to international quality standards. With state-of-the-art manufacturing facilities and a dependable supply chain, the company caters to industries like aerospace, electronics, cryogenics, instrumentation, and precision engineering around the globe.
Invar 36 Bars and Rods are primarily made of iron, with about 36% nickel, giving them an incredibly low coefficient of thermal expansion at room temperature. This unique composition ensures excellent dimensional stability and strong resistance to thermal distortion. On the mechanical side, Invar 36 boasts moderate tensile strength, good ductility, and impressive toughness. While it’s not designed for high-strength structural applications, it reliably maintains its mechanical and dimensional properties across a broad temperature range.

Yes, Invar 36 bar and rod can be welded, but it requires special care due to its low expansion properties. Proper welding techniques, such as TIG or MIG, are recommended.
Yes, specific welding consumables for Invar 36 bar and rod include Invar 36 electrodes, TIG rods, and MIG wires. These materials ensure proper fusion and minimize thermal expansion issues during welding.
Invar 36 rod, primarily composed of iron and nickel, is not highly susceptible to galvanic corrosion. However, when exposed to more noble metals in corrosive environments, it can experience some galvanic effects.
Invar 36 Bars and Rods find their niche in applications where minimal dimensional changes occur with temperature variations. They are commonly used in precision instruments, aerospace tooling, satellite structures, optical components, cryogenic vessels, and measuring devices. These materials are also extensively utilized in electronics manufacturing, telecommunications, scientific research equipment, and aerospace assemblies. Additionally, Invar 36 bars and rods are ideal for molds, frames, and structural components where thermal stability, accuracy, and long-term dimensional reliability are essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
