Grounding rods are made by introducing French technology and adopting unique production process. The product combines both the low resistance, high corrosion resistance and good electrical connection of copper and the high strength and easy construction of steel, which is the best choice to replace traditional metal grounding materials. The product adopts French electroforming technology, the copper layer is knotted into one, has good plasticity, can be rolled thread, can be bent, convenient transportation and construction, can be widely used in power transmission and transformation, power stations, communication base stations, buildings and antennas grounding device, and lightning catcher (lightning rod, lightning wire) and lead wire to form a lightning protection grounding system.

Alloy Manufacturing Principles Editorial Podcast
(1) All elements without exception reduce the electrical and thermal conductivity of copper rods, where the elements solid solution in copper rods, resulting in lattice distortion of copper rods, so that the free electron directional flow when the wave scattering, so that the resistivity increases, on the contrary, there is no solid solubility in copper rods or very little solid solution of the elements, the conductivity and thermal conductivity of copper rods have little effect, it should be particularly noted that some elements in copper rods solid solubility as the temperature decreases and fiercely It should be particularly noted that some elements in the copper rod solid solution degree as the temperature decreases, to single and metal compounds precipitation, both solid solution and dispersion strengthening copper rod alloy, but also on the conductivity of the reduction is not much, which is important for the study of high strength and high conductivity alloy alloying principles, here should be particularly noted that the four elements of iron, silicon, zirconium (not wrong), chromium and copper rod alloy is extremely important high strength and high conductivity alloy; because the alloying elements on copper rod performance is superimposed, which CoCr -Zr system alloy is a well-known high-strength and high-conductivity alloy.
(2) The organization of copper-based corrosion-resistant alloys should be single-phase to avoid electrochemical corrosion caused by the presence of a second phase in the alloy. For this reason the alloying elements added to the copper bar should have a large solid solution, or even an infinite number of mutually soluble elements, in engineering applications of single-phase brass bars, bronze bars, white copper bars have excellent corrosion resistance, is an important heat exchange material.
(3) There are soft and hard phases in the organization of copper-based wear-resistant alloys, so the alloying must ensure that the added elements should have hard phase precipitation in addition to solid solution in the copper rod, and the typical hard phases in the copper rod alloy are Ni3Si, FeALSi compounds, etc. The a phase should not be greater than 10 %.
(4) The solid state has polycrystalline transformation of copper rod alloy has damping properties, such as Cu a Mn alloy, the solid state has a thermoelastic martensitic transformation process of the alloy has memory properties, such as Cu a Zn a Al, Cu a Al a Mn alloy.
(5) The color of copper rods can be changed by adding alloying elements, such as zinc, aluminum, tin, nickel and other elements, with the change of content, the color also occurs red, green, yellow and white changes, reasonable control of the content will get imitation gold materials and imitation silver alloy.
(6) copper rods and alloys of alloying the selected elements should be commonly used, cheap and non-polluting, the elements added should be in line with the principle of multiple small amounts, alloy raw materials can be used comprehensively, the alloy should have excellent process performance, suitable for processing into a variety of finished and semi-finished products.
