Super Invar is an advanced nickel–iron–cobalt alloy with an extremely low coefficient of thermal expansion, even lower than standard Invar 36. It is widely used in aerospace, cryogenic engineering, optics, and precision measurement instruments. Because of its high nickel and cobalt content, the factory price of Super Invar is considerably higher than common steels or even standard Invar plates and bars.
What is the Average Factory Price of Super Invar?
The factory price for Super Invar depends on product type (plate, rod, strip), dimensions, and order quantity. Typically, suppliers in China offer more competitive prices compared with Europe or the US. Below is an estimated price range based on common specifications:
| Product | Specification | Factory Price (USD/kg) |
|---|---|---|
| Super Invar Plate | 3mm – 20mm thickness | $75 – $95 |
| Super Invar Rod | Ø10mm – Ø80mm | $80 – $100 |
| Super Invar Strip | Cold rolled precision strip | $90 – $120 |
Factory Price by Region
Buyers sourcing Super Invar directly from the factory will see clear regional differences in pricing:
| Region | Estimated Factory Price (USD/kg) | Notes |
|---|---|---|
| China | $70 – $95 | Competitive bulk pricing, faster delivery, lower labor cost. |
| Europe | $95 – $130 | Premium quality, strict certifications, higher production costs. |
| United States | $100 – $140 | Guaranteed traceability, aerospace certifications, higher local cost. |
Factors Influencing Super Invar Factory Price
| Factor | Impact |
