The product is an iron‑nickel low‑expansion alloy known as Pernifer 36, containing a nominal 36 % nickel with the balance iron, together with 0.02 % carbon, 0.35 % manganese and 0.20 % silicon. It conforms to the ASTM F1684 standard for low‑expansion alloys. Xian Gangyan Special Alloy Co., Ltd. manufactures the alloy in China and offers it in bulk for industrial import. The alloy’s minimal thermal expansion makes it suitable for applications that demand dimensional stability.
The material is supplied in typical forms such as bars, sheets and plates, allowing manufacturers to select the geometry that best fits their design. Standard industry data lists a thermal expansion coefficient of about 1.2 µm/(m·°C) and a density near 8.05 g/cm³, both of which are characteristic of Invar‑type alloys. Mechanical properties generally include a Young’s modulus around 141 GPa and a tensile strength of roughly 350 MPa, providing the strength needed for precision components. Xian Gangyan’s catalogue notes that the alloy meets the composition limits defined in ASTM F1684, ensuring consistency across batches.
Typical end‑users are manufacturers of precision measurement instruments, aerospace structures, optical mounts and LNG vessel components that require low thermal drift. Buyers usually arrange trade under FOB or CIF terms, negotiating volume‑based pricing according to current nickel market conditions. Prospective importers should confirm the minimum order quantity, packaging format and required certification with the supplier before finalising the contract.

Xian Gangyan Special Alloy Co., Ltd. is located at No. 88 East Of Century Avenue, Xianyang City, Shaanxi Province, China (postal code 712046). The supplier carries a harbour trust tier and currently shows a response rate of 0.00, indicating that no recent replies have been recorded in the platform’s metrics.
The company specialises in the production and export of specialised iron‑nickel alloys for precision applications. Its public listing states that it can provide custom alloy orders that meet ASTM F1684 requirements, but it does not disclose specific certifications, minimum order quantities or client references.
Invar 36, also known as Pernifer 36 or NILO 36, is a precision iron-nickel low expansion alloy meeting ASTM F1684 specifications, with a nominal composition of 36% Ni balance Fe, featuring minimal thermal expansion at ambient temperatures. Widely used in precision measurement instruments, aerospace components, optical mounts, and LNG vessel construction where dimensional stability under temperature variation is critical. As a specialized nickel alloy import, pricing reflects current nickel market conditions and is subject to negotiation based on volume and form.

Before placing an order, importers should obtain the mill test certificate and a recent chemical analysis report to verify that the alloy meets the 36 % nickel composition and ASTM F1684 requirements. It is also advisable to confirm any minimum order quantity, packaging dimensions and whether the supplier can provide additional heat‑treatment documentation if required for the final application.
Logistics for this product typically involve shipment from a Chinese port such as Tianjin or Shanghai under FOB or CIF incoterms. Lead times are not stated in the listing, so buyers must ask the supplier for an estimated production and dispatch schedule. Payment terms are usually negotiated per transaction and may include a letter of credit or advance payment, depending on the volume and relationship.
Quality control for imported low‑expansion alloys often includes third‑party inspection, dimensional verification, and non‑destructive testing to confirm the thermal expansion performance. Importers should arrange for an inspection agency to verify the alloy’s physical properties and request all relevant documentation, including the mill test certificate, chemical analysis and any applicable conformity certificates, before acceptance at the destination port.
