Dongguan extrusion hard aluminum copper bar manufacturer, take you to understand the purpose of the abnormal copper bar

The reason why it is called shaped copper, mainly because of its special section shape. That is to say, compared with the copper bars usually used in flat, the cross-section shape of the special-shaped copper bars is not square or rectangle, but has different shapes. Among them include "L" type, "T" type, ladder type, multilateral and multi-angle type, mostly according to the manufacturer's specific product design requirements.

Due to its excellent electrical conductivity, the special-shaped copper bar is mainly used as the main raw material for making switch contacts of electrical appliances of various specifications and wires for power installation. In the actual processing, most of the non-oxygen copper rod is extruded by continuous extruder with cold drawing machine cold drawing forming process.

Shaped copper row forming process:

In the process of processing, the continuous extrusion of special-shaped copper bar is mainly used to produce the copper rod as the blank material. Driven by the extrusion wheel, the copper bars of different specifications can be extruded continuously through the mold. The maximum width of copper bars can be more than 300mm.

By comparison, the extrusion technology can simplify the process flow and has higher production efficiency. Moreover, the obtained products have the advantages of high yield, good surface quality, excellent electrical performance, energy saving and environmental protection.

We know that, like the ordinary copper bar, in fact, the special-shaped copper bar is also a kind of high-current conductive product, which can be applied to high-voltage and low-voltage appliances, switch contacts, power distribution equipment, busway and other electrical engineering, and also widely used in metal smelting, electrochemical electroplating, chemical caustic soda and other super-current electrolytic smelting projects.

High-quality special-shaped copper products should meet the following requirements: 1. Low resistivity, high bending; 2. 2, smooth surface, clean, no cracks, peeling, bubbles, inclusions and other defects; 3. There are no pores, layering and inclusions inside the product; 4. The conductivity of special-shaped copper bar products is above 57s/m and above 98%.
