Non-Magnetic Copper-Nickel Alloy Flat Wire 0.6*3mm CuNi6 For Low-Voltage Circuit Breakers

Product Description

Chemical Content, %

1. Composition: It is a copper-nickel alloy with approximately 94% copper and 6% nickel.

2. Physical properties:

• Density: It has a density of about 8.9 g/cm³.
• Resistivity: The electrical resistivity at 20 °C is 0.1 Ω·mm²/m, which is relatively higher than that of pure copper, making it suitable for certain resistance applications.
• Melting point: The melting point is around 1095 °C.
• Coefficient of thermal expansion: From 20 °C to 400 °C, the coefficient of thermal expansion is 17.5 × 10⁻⁶ /K.
• Specific heat capacity: At 20 °C, the specific heat capacity is 0.380 J/gK

​3. Mechanical properties:

• Strength: It has a yield strength of 110 MPa and a tensile strength of 250 MPa (for a 1.0 mm sample), showing relatively good mechanical strength.
• Elongation: The elongation is 25% (for a 1.0 mm sample), indicating a certain degree of ductility.

4. Other properties:

• Temperature resistance: It can be used at temperatures up to 220 °C and has good stability at high temperatures.
• Magnetic properties: It is non-magnetic.
• Corrosion resistance: It has good corrosion resistance in the atmosphere at 20 °C, but the corrosion resistance is relatively poor in some specific gas environments such as those containing sulfur.

DIN spools are available for the package as per your requests.

Stranded or bunch wires are available if you need.

Enamelled wire can be tailor-made.
