FAQ:

1. What is the composition of CuNi8 alloy?

CuNi8 typically contains around 92% copper and 8% nickel, with small traces of iron and manganese. This balance offers good mechanical strength and moderate corrosion resistance.

2. What industries typically use CuNi8 super alloy bars?

CuNi8 bars are commonly used in marine hardware, heat exchangers, electrical resistors, offshore oil systems, and instrumentation applications where moderate corrosion resistance and stable conductivity are needed.

3. Can CuNi8 bars be customized in terms of size and shape?

Yes, we offer full customization, including round, square, or flat bar shapes. Lengths and diameters can be tailored according to your technical drawings or specific project requirements.

4. What is the temperature resistance of CuNi8?

CuNi8 performs well in elevated temperature environments up to approximately 400°C, maintaining structural stability and electrical properties in both dry and moist atmospheres.

5. How does CuNi8 compare to CuNi10 or CuNi30 in corrosion resistance?

CuNi8 offers lower corrosion resistance than CuNi10 and CuNi30, but it is more cost-effective and sufficient for non-aggressive environments. CuNi30 is preferred for highly corrosive marine applications, whle CuNi8 suits electrical and industrial usage.

6. Do you provide mill test certificates and quality documentation?

Yes, every shipment includes a Mill Test Certificate (MTC) with chemical composition and mechanical properties. Additional third-party inspection or SGS reports are available upon request.

7. What is your minimum order quantity (MOQ) for customized CuNi8 bars?

Our MOQ for customized CuNi8 super bars usually starts from 100 kg, but we can offer lower quantities for sampling or pilot projects. Please contact us for flexibility based on your order.

8. What is the lead time for bulk orders of CuNi8 super bars?

Standard lead time ranges from 15 to 25 working days depending on quantity and customization level. Urgent orders can be fast-tracked under our expedited production program.
