How Much Does Invar Cost per kg in 2025?

Invar is a nickel-iron alloy (typically 36% Ni and balance Fe) known for its extremely low coefficient of thermal expansion. It is widely used in precision instruments, aerospace tooling, cryogenic applications, and electronics. Due to its unique properties and limited production sources, Invar pricing tends to be higher than common stainless steels or carbon steels. Below is a detailed breakdown of Invar alloy pricing in 2025.

Invar Price Per kg in 2025 (Estimated Range)

Prices vary depending on product form (plate, bar, wire, sheet), processing (hot-rolled, cold-rolled, annealed), country of origin, and order volume. Here is a general reference:

Major Producers of Invar

The global supply of Invar is limited to a few specialized producers with the technical capability to control its expansion properties. Below is a list of major manufacturers:

Factors Affecting Invar Price

1. Nickel Price: Invar contains 36% nickel, so price closely tracks LME nickel market trends.

2. Dimensional Tolerance: Precision strips and foils with tight flatness and thickness tolerances cost more due to more complex production.

3. Certification Requirements: Aerospace or cryogenic grade Invar (AMS/IACS certified) costs 10–20% more.

4. Quantity: Small quantity orders (under 100 kg) typically incur premiums of 15–30% per kg.

What is the price of Invar sheet per kg?

In 2025, cold-rolled Invar sheet typically costs between 32–42 USD/kg, depending on thickness and supplier origin.

Why is Invar expensive?

Invar is expensive due to its high nickel content (36%), tight control in metallurgy, and limited production globally.

Where can I buy small quantities of Invar?

Suppliers like JLC Electromet (India), Phoenix Alloy (China), and online distributors like Ed Fagan Inc. offer small lot sizes as low as 5–10 kg with precision cut services.
