The product is Nickel Iron Sealing Alloy 52 supplied by Xian Gangyan Special Alloy Co., Ltd. The alloy composition is nominally 50 % nickel with iron making up the balance, as stated in the listing. It is marketed for glass‑to‑metal and ceramic‑to‑metal sealing applications where a constant thermal expansion coefficient is required. The alloy complies with ASTM F30 and related international specifications for composition and thermal performance. The seller notes that the material is available in ingot, rod and strip forms for export.
Alloy 52 is a controlled‑expansion material widely used in aerospace, electronic and sensor assemblies because its coefficient of thermal expansion remains nearly constant up to about 565 °C (1 050 °F). A nickel content of 50 % is typical for sealing grades that need to match soft glass expansion, and standard processing yields a density near 8.1 g cm‑3 with a melting range around 1 250 °C. The supplier’s description aligns with the ASTM F30 grade without mentioning additional alloying elements.
Primary customers include manufacturers of vacuum tubes, semiconductor packages and high‑precision sensors that require hermetic seals. Importers usually arrange freight under FOB or CIF terms, but the listing does not specify the incoterm or port of loading. Because the supplier does not disclose minimum order quantities, lead times or payment conditions, buyers should request those details to align with production schedules. The alloy’s proven performance in high‑temperature sealing makes it a strategic material for aerospace and electronics supply chains.

Importers should first obtain a full chemical analysis confirming the 50 % nickel and 50 % iron balance, together with the ASTM F30 compliance certificate. Verifying the supplier’s registered address in Xianyang and ensuring that the stated forms (ingot, rod, strip) match the required dimensions are essential steps before contract finalisation. Any deviation from the nominal composition must be documented and agreed upon.
The product can be shipped under FOB or CIF terms, but the listing does not specify the loading port or incoterm, so buyers must clarify these details with the supplier. Expected transit time from inland China to major Asian ports typically ranges from two to four weeks, depending on vessel schedules. Payment methods such as T/T against documents or a confirmed letter of credit should be negotiated and recorded in the purchase agreement.
Upon receipt, the alloy should be inspected for surface defects, dimensional conformity and proper labeling before acceptance. A third‑party assay or on‑site sampling can verify that the thermal expansion characteristics meet the required specifications. Requesting the mill test report, certificate of origin and any heat‑treatment records will help streamline customs clearance and downstream quality control.
