Frequently Asked Questions

What is invar 36?

Invar 36 is a nickel-iron alloy containing approximately 36% nickel that exhibits extremely low thermal expansion properties. This unique characteristic makes it invaluable for applications requiring dimensional stability across varying temperatures.

Why is invar so expensive?

Invar is expensive due to its high nickel content, complex manufacturing process, and specialized applications. The precise control required during production and the material's unique properties contribute to its higher cost compared to standard steels.

Is invar 36 stainless steel?

No, Invar 36 is not a stainless steel. It is a nickel-iron alloy specifically designed for low thermal expansion. Unlike stainless steel, it does not contain significant amounts of chromium and may require additional surface treatment for corrosion resistance.

What is the difference between Inconel and invar 36?

While both are nickel alloys, they serve different purposes. Invar 36 is designed for minimal thermal expansion, while Inconel is engineered for high-temperature strength and corrosion resistance. Inconel typically contains more chromium and can withstand higher temperatures.
