1. What is C71300 copper-nickel pipe/tube?

C71300 white copper is a structural copper-nickel alloy.

ASTM C71300 requirements are met by the structural copper-nickel alloy known as C71300 white copper. It is appropriate for pressure processing in both hot and cold environments due to its good mechanical qualities and resistance to corrosion. Its mechanical characteristics and resistance to corrosion are better than those of B5.B19 because of the increased nickel content.

The characteristics and application scope of C71300 white copper include:

1. High mechanical properties: White copper C71300 is incredibly strong and resilient, making it ideal for structural applications subjected to high loads and pressures.

2. Corrosion resistance: C71300 white copper has good corrosion resistance and can withstand oxidation due to its high nickel content.

3. Good plasticity and processability in both hot and cold conditions: C71300 white copper can be produced and processed using pressure processing.

4. Wide range of uses: C71300 white copper is frequently utilized in the production of auto parts, instrumentation, electronic components, chemical equipment, ship parts, and other parts.
