What Are Invar 36 Sheets and Plates?
Invar 36 is a controlled-expansion nickel-iron alloy containing approximately 36% nickel with iron making up the balance. It is identified as UNS K93600 in Nickel Institute technical information.
Its most important characteristic is its very low coefficient of thermal expansion around room temperature. Nickel Institute notes that Invar has an expansion rate approximately one-tenth that of ordinary steel within a commonly used temperature range.
This makes Invar 36 particularly useful for components that must maintain their dimensions when exposed to temperature changes.
Invar 36 Sheets and Plates can be processed into fabricated components, precision fixtures, structural elements and specialised engineering parts where dimensional stability is more important than conventional material selection.
Why Is Invar 36 Used for Precision Applications?
Temperature changes can cause ordinary engineering materials to expand or contract. In precision equipment, even a small dimensional change can affect alignment, calibration or operating accuracy.
Invar 36 addresses this challenge through its unusually low thermal expansion characteristics.
According to the Nickel Institute, Invar has historically been used in precision measuring devices, gauges, clamps and fixtures requiring dimensional stability, as well as temperature-control components and specialised aerospace and electronic applications.
This makes the material valuable when engineers need a metal that experiences comparatively limited dimensional movement as operating temperature changes.
Key Characteristics of Invar 36
| Property / Characteristic | Invar 36 |
|---|---|
| Material family | Nickel-Iron alloy |
| Nominal nickel content | Approximately 36% |
| UNS designation | K93600 |
| Primary characteristic | Very low thermal expansion |
| Dimensional stability | Excellent for controlled-expansion applications |
| Typical forms | Sheet, plate and other mill forms |

The exact mechanical, thermal and dimensional properties depend on the applicable specification, product form, thickness, processing condition and heat treatment.
For demanding engineering projects, the material certificate and applicable standard should always be reviewed before final fabrication.
Applications of Invar 36 Sheets and Plates
Invar 36 is selected for applications where temperature-related dimensional movement needs to be minimised.
Precision Measuring Equipment
Measurement equipment can require exceptional dimensional stability. Invar 36 can be used in specialised components where temperature-related expansion could influence measurement accuracy.
Jigs, Fixtures and Tooling
Manufacturing fixtures may need to maintain accurate dimensions during changing operating conditions. Invar 36 can be considered for precision tooling and fixtures requiring controlled thermal expansion.
Aerospace Applications
Invar alloys have applications in aerospace-related components where dimensional stability and predictable thermal behaviour are important. Nickel Institute technical literature identifies aircraft and specialised aerospace components among historical and modern applications.
Electronics and Instrumentation
Controlled-expansion nickel-iron alloys are also used in specialised electronic and instrumentation applications. Their thermal characteristics can help maintain dimensional relationships in temperature-sensitive assemblies.
Cryogenic and Liquefied-Gas Applications
Invar’s low thermal expansion and useful low-temperature properties have supported applications involving liquefied gases and cryogenic environments. Nickel Institute literature specifically discusses its use in LNG containment applications.
Invar 36 Sheet and Plate Specifications
When sourcing Invar 36 Sheets and Plates, the specification should be selected according to the actual engineering requirement.
Important purchasing details include:
- Material: Invar 36
- UNS designation: K93600
- Product form: Sheet or plate
- Required thickness
- Required width and length
- Surface condition
- Heat-treatment condition
- Applicable ASTM or other project specification
- Quantity required
- Test certificate requirements
- Cutting or fabrication requirements
Invar 36 can be available in several product forms. Nickel Institute documentation identifies the alloy in forms including plate, strip, sheet, pipe, tubing, bars, billets, forgings and wire.
For specialty-material procurement, providing complete dimensional and certification requirements helps suppliers identify the appropriate material more efficiently.
Benefits of Buying Invar 36 from a Specialist Supplier
Sourcing specialty alloys is different from purchasing standard commercial steel products. Material traceability, specification accuracy and documentation can be important for engineering applications.
A specialist supplier can help with:
Material Identification
The correct material designation should be confirmed before order processing.
Dimensional Requirements
Thickness, width and length requirements can be checked against available stock or sourcing possibilities.
Documentation
Industrial buyers may require material test certificates and other documentation depending on their internal quality procedures and project requirements.
Application-Based Sourcing
A specialist supplier can understand whether the requirement is for precision tooling, instrumentation, aerospace-related fabrication, cryogenic service or another application.
Custom Procurement
For non-standard sizes or quantities, availability may need to be checked with mills and authorised supply channels.
How to Select the Right Invar 36 Material
Before purchasing Invar 36 Sheets and Plates, industrial buyers should provide the supplier with:
- Required thickness
- Sheet or plate dimensions
- Quantity
- Required material specification
- Application or service environment
- Heat-treatment requirements, if applicable
- Surface finish requirements
- Certification requirements
- Cutting requirements
- Delivery location
This information can reduce delays and help ensure that the material supplied matches the project’s technical requirements.
Factors Affecting Invar 36 Sheet and Plate Price
Invar 36 Sheets and Plates Price India can vary considerably depending on the order specification.
Important pricing factors include:
- Thickness
- Width and length
- Total quantity
- Material availability
- Required specification
- Surface finish
- Heat-treatment condition
- Test certificates
- Cutting requirements
- Packaging
- Freight and delivery location
- Market conditions for nickel and specialty alloys
Because Invar 36 is a specialised nickel-iron alloy, pricing should generally be requested against the exact size, quantity and specification rather than relying on a generic per-kg estimate.
