Yes, for welding Invar bars, dedicated consumables such as Invar welding rods, Invar electrodes, or Ni-based filler metals like ERNi-1 or ERNiCrMo-3 are frequently employed to achieve the best possible bond and reduce thermal expansion problems.
Yes, Invar bar and rod are weldable, generally by means of TIG or MIG welding methods. That said, it demands careful heat management to prevent distortion caused by its low expansion characteristics.
Invar rods, made mainly of iron and nickel, tend to resist galvanic corrosion. Nevertheless, when combined with more reactive metals, they can corrode if subjected to electrolyte solutions.
Invar Bars and Rods are suited to industries requiring materials that offer minimal thermal expansion and high dimensional accuracy. They are commonly applied in aerospace for precision instruments, structural components, and optical assemblies. Within the electronics sector, Invar serves in semiconductor fixtures, circuit components, and precision measuring devices. This alloy is likewise well-suited for scientific instruments, optical benches, and mechanical parts that respond to temperature variations. Its exceptional thermal stability, combined with adequate mechanical strength, makes it a preferred option across a range of demanding applications.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
