The main production material of purple copper plate is copper, copper use: much more extensive than pure iron, every year 50% of the copper is purified into pure copper electrolysis, used in the electrical industry. The copper said here is a higher purity, more pure copper, its copper content needs to reach more than 99.95%. Very small amounts of impurities will greatly reduce the conductivity of copper, especially phosphorus, arsenic, aluminum and other components.

Because of the small section of the tunnel guide, purple copper plate has good conductivity, thermal conductivity, corrosion resistance and processing performance, can be welded and brazed, containing reduced conductivity, thermal conductivity impurities less, trace oxygen has little effect on the conductivity, thermal conductivity and processing performance, but easy to cause "hydrogen disease", should not be processed and used in high temperature (such as > 370℃) reducing atmosphere. Copper plate light weight, good flexibility, easy construction. The corrosion resistance of the copper plate is better, which can ensure the waterproof effect of the tunnel in a long time.

Copper plate has unique excellent performance, is the electrical industry manufacturing circuit breaker, contact conductive plate, low-voltage air switch conductive accessories and other ideal replacement material. The product microstructure grain refinement degree is good, compared with pure copper plate and copper-iron alloy plate, tensile strength increased by 10.4%, hardness increased by 3%, copper plate conductivity increased by 4.5%, compared with imported alloy plate increased by 2.8%, wear resistance has been significantly improved. Reach the international advanced level. The use of this plate to manufacture electrical accessories can improve the quality, prolong the service life of products and ensure public safety. Copper elongation is better, in the partition wall under pressure, shear, uneven settlement, waterproof plate is not easy to damage.

The color of pure copper is rose red, and it is purple after the formation of copper oxide film on its surface, so pure copper is often called red copper or electrolytic copper in industrial production. Fire smelting can obtain 99- 99.9% pure copper, electrolytic copper purity can reach 99.95- 99.99%. Density of 8-9g/cm3, melting point 1083°C. Pure copper conductivity is very good, a large number of used in the manufacture of wire, cable, brush, etc.; Good thermal conductivity and wide application scenarios.
