The product is Nickel Iron Alloy 48, also known as Nilo 48, conforming to ASTM F30 and designated UNS K94800. Its nominal composition is 48 % nickel with the balance iron, as specified by the supplier. The alloy is supplied by Xian Gangyan Special Alloy Co., Ltd., located in Xianyang City, Shaanxi Province, China. It is marketed in bar, rod and sheet forms for industrial use.
This low‑expansion alloy exhibits a coefficient of thermal expansion that closely matches soda‑lime glass, a property valued in glass‑to‑metal seals. The material can operate continuously up to 450 °C (840 °F) without significant loss of dimensional stability. Typical commercial grades of this alloy have a tensile strength around 620 MPa and a Rockwell B hardness near 80, although exact values should be confirmed per batch. Standard packaging for bulk shipments includes crate‑packed bars or coils wrapped in protective film, complying with common export practices.
Primary applications include precision instrumentation, bipolar plates for fuel cells, and electronic component housings where thermal matching is critical. Buyers such as aerospace manufacturers, electronics assemblers and glass‑seal equipment makers commonly source this alloy in large quantities. Trade details including minimum order quantity, lead time and Incoterms are not listed and should be clarified directly with the supplier.

Before placing an order, confirm that the alloy grade matches UNS K94800 and that the mill test certificate details the exact nickel content, carbon residuals and heat‑treatment condition. Ask for a recent chemical analysis report and a dimensional tolerance sheet to ensure the material will meet your engineering specifications. Verifying these documents reduces the risk of receiving a non‑conforming batch.
Logistics from Xianyang typically involve freight forwarding from nearby ports such as Tianjin or Qingdao. Discuss preferred Incoterms - FOB, CIF or DAP - and ask the supplier for an estimated lead time based on the required quantity. Payment terms are usually negotiated as T/T, L/C or open account, and should be clarified in the contract before shipment.
Arrange for third‑party inspection or pre‑shipment sampling to validate conformity with the agreed specifications. Request inspection reports covering visual checks, dimensional verification and mechanical testing. Ensure that the supplier provides all necessary export documentation, including the commercial invoice, packing list, certificate of origin and any required customs paperwork.
