Copper strip control surface quality measures
Copper strip high purity, fine tissue, oxygen content is very low. It has good electrical conductivity, thermal conductivity, corrosion resistance and machining properties, and can be welded and brazed. Measures to control the surface quality of red copper strip: first of all, we should strengthe...Read more -
Brass strip application and processing
Brass strip is a long conductor of rectangular or chamfered sections made of copper, used to carry current in circuits and connect electrical equipment. Because copper is better than aluminum in conducting electricity, brass strip has been widely used in electrical equipment, especially in power ...Read more -

Preparation method and application of high purity copper
High purity copper refers to the purity of copper reaches 99.999% or higher 99.9999%, and its various physical properties are greatly improved than those with low purity. Copper has good electrical and thermal conductivity, and it is malleable and malleable. Copper is commonly used to make wires ...Read more -
The technology of tungsten copper electroplating was analyzed
Tungsten copper alloy not only has the low expansion characteristic of tungsten, but also has the high thermal conductivity characteristic of copper. By changing the proportion of tungsten and copper, the thermal expansion coefficient and thermal conductivity function of tungsten and copper alloy...Read more -
Thick-walled aluminum bronze production process
Using physical principles, the purity of thick-walled aluminum bronze can be measured, the volume and mass of the sample can be measured, and the proportion of copper in bronze can be calculated based on the density of copper and zinc. A multi-component alloy made by adding other alloying element...Read more -
Solutions to common problems with copper tape
1. The solution to the discoloration of copper tape (1) Control the concentration of acid solution during pickling. In the case of washing off the oxide layer on the surface of the annealed copper strip, a high acid concentration does not make any sense. On the contrary, if the concentration is t...Read more
