What is copper alloy strip?

Copper alloy coil strip is a strip material composed of copper, zinc, nickel and other alloys. Among them, the proportion of copper in its alloy is 60-98%, the proportion of zinc is 2-40%, and the proportion of nickel ranges from 0-5%. Copper alloy tape has good electrical conductivity and corrosion resistance, so it is widely used in electronics, manufacturing and other fields.

Characteristics of copper alloy coils

1. Good electrical conductivity: Copper alloy tape has good electrical conductivity, can effectively transmit current, and is suitable for high-frequency and high-speed circuits.

2. Good corrosion resistance: Copper alloy tape has excellent corrosion resistance and can be used for a long time in humid, acidic, high temperature and weathered environments without being easily damaged.

3. Good processing performance: Copper alloy coiled tape is easy to process and form, and can be made into coiled tapes with different precisions and sizes according to needs.

4. Low melting point: The melting point of copper alloy tape is lower than that of pure copper. It is easy to fuse and weld, and is convenient for making electronic components.

5. Good fatigue resistance: Copper alloy coil strip can withstand multiple bends without breaking easily. It has good fatigue resistance and is suitable for occasions that require frequent deformation.
