Constantan Nickel Resistance Alloy Wire
Constantan Nickel Resistance Alloy Wire is an alloy of copper and nickel supplied by Jiangyin Chengxin Alloy Material Co., Ltd in China. The alloy contains roughly 55 % copper and 45 % nickel, delivering a low temperature coefficient of resistance across - 100 °C to +600 °C. The wire is offered in various diameters and can be delivered on spools or as cut lengths. Batch consistency is highlighted for OEM and replacement part buyers.
In the resistance‑wire market, Constantan is recognised for its stable resistivity and corrosion resistance, attributes that align with standard ASTM B170 specifications. Typical commercial grades are supplied with diameter tolerances of ±0.02 mm and resistance tolerance of ±5 %. The material’s low TCR makes it suitable for precise temperature measurement devices, and its mechanical strength meets the demands of heating elements. Suppliers often provide the wire without insulation, allowing end users to apply suitable jackets.
Industrial heating manufacturers, thermocouple producers and precision resistor makers are the primary purchasers of this alloy wire. Jiangyin Chengxin notes that order quantities and delivery schedules are negotiated per project, and buyers should confirm minimum order quantities, lead times and preferred Incoterms directly with the company. Payment can be arranged through standard letters of credit or telegraphic transfer, subject to agreement.

Sourcing Constantan Nickel Resistance Alloy Wire from Jiangyin Chengxin Alloy Material Co., Ltd - China Import Guide
Before placing an order, importers should request a material test report confirming the Cu 55 %/Ni 45 % composition and verify the wire’s temperature coefficient as per the supplied data sheet. It is prudent to ask for a sample batch to assess diameter consistency and resistance values against the typical ±5 % tolerance. Confirm that the supplier can provide the required diameter range and that any custom length specifications are feasible.
Logistics arrangements should be clarified early; buyers need to know whether the wire will be shipped FOB the port of Shanghai or CIF to a destination port in their region. Lead‑time estimates are not listed, so a realistic production and dispatch schedule must be obtained from the supplier. Payment methods commonly accepted include letters of credit and telegraphic transfer, but the exact terms should be negotiated in the contract.
Quality assurance can be reinforced by requesting an ISO‑9001 or SGS inspection certificate, even though the listing mentions such certifications without providing copies. An independent third‑party inspection at the factory or at the loading port can verify dimensional tolerances, resistance values and surface condition. Importers should also ensure that the supplier supplies a declaration of conformity with relevant standards such as ASTM B170, to simplify customs clearance and downstream testing.
