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.
These Invar 36 Bars and Rods find extensive use in industries that require high precision despite temperature fluctuations. They’re perfect for aerospace tooling, composite molding, and structural components in aircraft. In the electronics sector, they’re utilized for shadow masks, CRTs, and semiconductor manufacturing equipment. Scientific research facilities rely on them for cryogenic vessels, optical devices, and laser systems. Additionally, they’re used in precision measurement instruments, molds for carbon fiber production, and any application where consistent performance across temperature changes is vital.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
