Invar (UNS K93600) – Ultra-Low Expansion Alloy for Precision & Mission-Critical Applications

Invar (Fe-Ni 36 alloy) is the industry standard material for applications requiring extremely low thermal expansion and long-term dimensional stability. Specified across aerospace, composite tooling, cryogenic systems, precision instrumentation, RF equipment, and energy infrastructure, Invar ensures structural integrity and alignment even under severe thermal cycling.

It is widely used in carbon fiber molds for advanced aircraft platforms such as the Boeing 787 and Airbus A350, satellite structural components, laser housings, optical assemblies, LNG membrane tanks, and high-capacity power conductors. Its stable coefficient of thermal expansion (CTE) minimizes distortion, frequency drift, structural stress, and thermal sag in high-precision environments.

With over 25 years of experience serving global OEMs and industrial buyers since 2001, we supply Invar in rods, sheets, plates, bars, and custom-machined components tailored to your specifications. Our focus is on:

• Tight dimensional tolerances

• Reliable global logistics & export compliance

• Consistent material traceability

• Competitive bulk pricing

• Technical support for specification matching

Whether you require prototype quantities or large-scale production supply, our team supports fast response times and detailed quotations to meet your project timelines.
