Iron Nickel Alloy ASTM F1684 Invar 36
The product is an Iron‑Nickel alloy known as Invar 36, conforming to ASTM F1684. Its nominal chemistry is 36 % Ni, balance Fe, with 0.02 % C, 0.35 % Mn and 0.20 % Si as listed by the supplier. Xian Gangyan Special Alloy Co., Ltd. offers the alloy in ingot, rod, sheet and wire forms. All dimensions and tolerances are supplied on request.
Invar 36 exhibits an exceptionally low coefficient of thermal expansion, typically around 1.2 × 10⁻⁶ /°C between - 100 °C and +100 °C, which makes it suitable for precision instruments. The alloy’s density is about 8.1 g cm⁻³ and its typical tensile strength lies near 450 MPa after standard heat treatment. It is widely used in aerospace structures, optical benches, laser systems and cryogenic devices where dimensional stability is critical. The supplier notes that the material is also marketed under the names NILO 36 and Pernifer 36 in regional markets.
Buyers such as OEMs of scientific equipment, defence contractors and specialty fabricators usually request bulk shipments in 20‑ft containers or rail‑car loads. The listing does not disclose minimum order quantity, lead time or payment terms, so these details should be confirmed directly with the supplier. Typical incoterms for this commodity include FOB Xianyang Port or CIF Shanghai, depending on the buyer’s logistics network. Inspection can be arranged under ISO 9001 procedures, and the supplier can provide mill test certificates upon request.

Sourcing Iron Nickel Alloy ASTM F1684 Invar 36 from Xian Gangyan Special Alloy Co., Ltd. - China Import Guide
Before placing an order, verify the alloy’s exact composition and request a mill test certificate that confirms ASTM F1684 compliance. Ask the supplier to provide recent assay data, heat‑treatment records and any relevant third‑party inspection reports, as these documents are essential for quality assurance in precision applications.
Logistics for Invar 36 are usually arranged on an FOB basis from Xianyang Port or on a CIF basis to major Asian or European ports. Confirm the incoterm that best fits your supply chain, negotiate payment terms such as T/T or LC, and clarify the expected lead time once the order size and form factor are finalised. Shipping containers or rail‑car loads are typical, but the supplier may accommodate alternative bulk handling methods upon request.
Quality control commonly involves third‑party inspection under ISO 9001 guidelines, with sampling performed either at the mill or at the port of loading. Request a full inspection report, including dimensional checks, tensile testing and surface condition assessment. Ensure that the supplier can supply all necessary documentation, such as a certificate of conformity and material safety data sheet, before the cargo is released for shipment.
