Production process and product advantages of C16200 copper wire:

1. Production process

Raw material preparation and melting and casting

The production starts with copper rods, and copper billets are prepared through melting and casting processes.

It is mentioned that milling treatment is required after melting and casting to ensure surface quality.

Stretching and annealing

Rough stretching: Use a large drawing machine to perform preliminary stretching on the copper rod, and lubricate it with emulsion to reduce friction.

Annealing treatment: Annealing is required after stretching to eliminate internal stress. The annealing temperature is between 371°C and 648°C, or high-temperature steam annealing is used.

and

Both mentioned that annealing is a core step that can improve the ductility of the material.

Multi-pass wire drawing: Multiple stretching is performed through a multi-head wire drawing machine. The micro-drawing process uses 24-pass die wire drawing technology, and the minimum diameter can reach 0.015mm.

Wire stranding and tinning

The wire stranding machine twists the copper wire to enhance flexibility.

Some products need to be tinned, and flux and tin are added to improve welding performance. Organic waste gas needs to be treated during the process.

Inspection and packaging

Inspection equipment detects wire quality, and unqualified products are returned to the melting section for reprocessing.

The finished product is finally packaged by an automatic film winding machine.

2. Product advantages

High strength and high conductivity

Contains 0.7%-1.2% cadmium. The addition of cadmium significantly improves the tensile strength (up to 690 MPa in hard state)

, while maintaining a high conductivity of 90% IACS, breaking through the limitation that traditional copper alloys are difficult to achieve both strength and conductivity.

Excellent processing performance

Both cold and hot processing performance are excellent, indicating that it is suitable for a variety of forming processes. However,

It is mentioned that the hot forming performance is poor, which may vary depending on the specific process conditions.

Supports welding (such as oxyacetylene welding, gas shielded welding) and forging (760-871°C), and the annealing temperature is flexible (371-648°C).

Corrosion resistance and high temperature resistance

Good corrosion resistance, suitable for harsh environments (such as strong acid, high temperature).

The melting point is as high as 1030-1080°C, the thermal conductivity is 360 W/m·K, and it is suitable for high-temperature applications.

Diverse application scenarios

It is used in electrical conductors, waveguides, railway contact lines, high-strength transmission lines and heating elements.

The spring has outstanding performance and strong resistance to stress relaxation. It is suitable for scenes that require repeated bending, such as telephone lines and aviation wires.

Environmental protection and energy saving

The continuous pulling and retracting technology and large-capacity retracting and releasing technology are used in the production process to improve efficiency and reduce energy consumption.
