When producing copper clad aluminum wire, you need to pay attention to the following key aspects to ensure product quality and production efficiency:<\/p>\n

1. Raw material selection<\/strong><\/p>\n

Aluminum core wire: The aluminum core must have good conductivity and toughness, and high-purity aluminum or aluminum alloy is usually selected as the base material.<\/p>\n

Copper strip quality: The copper layer needs to be made of high-purity copper material (such as oxygen-free copper) to ensure excellent conductivity and corrosion resistance.<\/p>\n

2. Process technology<\/strong><\/p>\n

Cladding welding technology:<\/p>\n

Ensure that the copper strip and the aluminum core are firmly fused through metallurgical bonding to avoid delamination or cracks.<\/p>\n

Use high-precision equipment to ensure uniform copper layer thickness during the cladding process.<\/p>\n

Drawing and annealing:<\/p>\n

The copper-aluminum ratio is kept constant during the drawing process to avoid breakage of the copper layer.<\/p>\n

The annealing process requires temperature control to prevent the material from becoming brittle or performance degradation.<\/p>\n

3. Dimension and tolerance control<\/strong><\/p>\n

According to standard requirements, the outer diameter and copper layer thickness of copper clad aluminum wire are strictly controlled.<\/p>\n

High-precision measuring equipment is used to ensure that the wire diameter error is within \u00b10.003mm or 1%.<\/p>\n

4. Surface quality<\/strong><\/p>\n

Make sure the surface is smooth and free of dents, cracks or exposed aluminum.<\/p>\n

For thinner wires, use a magnifying glass (no more than 10x) for inspection.<\/p>\n

5. Electrical performance test<\/strong><\/p>\n

Test the conductivity to ensure it meets the design requirements.<\/p>\n

Confirm the high-frequency signal transmission performance and verify whether the skin effect meets the application scenario.<\/p>\n
