Copper clad aluminum wire is prone to breakage during production, transportation and use, especially during drawing, rolling or long-term use. In order to prevent the breakage of copper clad aluminum wire, the following are some effective preventive measures:<\/p>\n

1. Control the production process<\/strong><\/p>\n

Temperature control: Temperature control is very important during the production of copper-clad aluminum wire. Too high or too low a temperature will increase the brittleness of the copper-clad aluminum wire, making it prone to breakage. Especially during the drawing and rolling process, controlling the cooling and heating process to ensure the grain refinement of the copper and aluminum materials helps to improve the toughness of the wire.<\/p>\n

Appropriate drawing speed and rolling pressure: Too fast drawing speed or too high pressure will cause excessive stress in the copper-clad aluminum wire, which will lead to breakage. During the production process, the drawing speed and rolling pressure should be reasonably adjusted according to the specifications, material properties and processing requirements of the wire to avoid excessive stretching.<\/p>\n

Uniform copper coating: During the manufacturing process of copper-clad aluminum wire, the copper layer must be evenly coated on the aluminum core. If the copper layer is uneven, stress concentration may occur in certain locations, causing the copper-clad aluminum wire to break during use. Ensure that the metallurgical bonding between the copper layer and the aluminum core is good to avoid internal stress in the copper-clad aluminum wire during drawing and use.<\/p>\n

Stress relief treatment: During the production process, annealing treatment is appropriately performed to eliminate the internal stress of the material. The annealing process can improve the ductility and fracture resistance of the copper clad aluminum wire and reduce the brittle fracture caused by stress concentration.<\/p>\n

2. Raw material selection and processing<\/strong><\/p>\n

High-quality raw materials: Selecting high-quality copper and aluminum materials is the key to preventing copper-clad aluminum wire from breaking. The quality of copper and aluminum directly affects the processing performance and service life of copper-clad aluminum wire. Copper should meet relevant national or international standards, and aluminum should be free of severe oxidation or impurities to ensure good metallurgical bonding during the production process.<\/p>\n

Removal of oxide layer: Before production, the oxide layer on the surface of the aluminum core must be completely removed. The oxide film of aluminum may cause the aluminum core and the copper layer to be loosely bonded, resulting in breakage during drawing and use.<\/p>\n
