Metal Alloy 99.995% Copper Round Bar Grind Surface

Description of  99.995% Copper Round Bar Grind Surface ：

Surface smoothness: After grinding, the surface smoothness of the 99.995% copper round rod has been significantly improved. During grinding, the copper material is ground and polished several times, reducing the surface roughness and making the surface smoother. This smooth surface reduces friction and wear and improves the corrosion resistance of the character.

Surface smoothness: Grinding processing makes the surface of 99.995% copper round rods more flat. During the grinding process, the copper material is finely ground and polished to eliminate surface defects and uneven areas and ensure the smoothness of the surface. This flat surface can improve the product's appearance quality and dimensional accuracy.

Surface hardness: Grinding can improve the surface hardness of 99.995% copper round rods. The copper material is ground and highly polished during the grinding process, making the surface harder and denser. 

Surface finish: The surface finish of the 99.995% copper round rod has been significantly improved through grinding. During grinding, the copper material is finely ground and polished to eliminate surface impurities and defects and make the surface more smooth. This high-finish surface can improve the electrical and thermal conductivity of the product so that it has a better application effect in the field of electronics and thermal engineering.

Surface oxide layer: In the grinding process, 99.995% of the surface of the copper rod may form an oxide film. This oxide film layer can protect the copper material from further oxidation and improve its corrosion resistance. However, if the oxide film is too thick or uneven, the quality and performance of the product may be affected. Therefore, it is essential to control grinding process parameters and environmental factors to reduce the formation of oxide layers.

Surface microstructure: Grinding may affect the surface microstructure of 99.995% copper round rod. The copper material is repeatedly ground and polished during grinding, and its grain size and orientation may change. These changes in microstructure may affect the mechanical properties, electrical conductivity and thermal conductivity of copper materials.

Surface stress: Grinding may cause residual stress on 99.995% of the copper rod surface. During grinding, residual compressive and tensile stresses may occur on the surface due to mechanical and thermal stresses on the material. These stresses may affect the mechanical properties and service life of the product. Therefore, optimizing the grinding process to reduce surface stress is essential.

Surface contamination: During the grinding process, 99.995% of the surface of the copper rod may be contaminated. For example, chemicals such as abrasives and polishes may remain on the product's surface. These contaminants may affect the properties and performance of products. Therefore, it is necessary to take effective cleaning measures to remove surface contaminants.
