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 -
Uses and Quality Control of Brass Rods
Brass rods are rod-shaped objects made of copper and zinc alloys, named for their yellow color. Brass with a copper content of 56% to 68% has a melting point of 934 to 967 degrees. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, ship...Read more -

Effects of Oxidative Coloring of Brass Rods
Brass rods are easily oxidized when exposed to the air for a long time, so is there any good measure to prevent the oxidation of brass rods? 1 Pair of brass rods are sealed and packaged, and two bags of desiccant are added at the same time. 2 The wooden shaft and the wooden box board are dried. 3...Read more -
Expert knowledge on storage methods of copper rods
Expert knowledge on storage methods of copper rods 1. We have to set up the warehouse. The temperature of placing the copper is 15 to 35 degrees in the middle. The oxygen-free copper rod and metal wire drawing copper plate must bypass the water source. What is the storage method of the copper rod...Read more -
Oxidation reasons and treatment methods of copper rods
The important factor affecting the surface quality of purple copper rods is the production process, and is closely related to all production processes. The reasons for the oxidation of red copper rods are as follows: 1. The pre-drying time of the insert is too long. 2. The acid corrodes the coppe...Read more -
What are the main varieties of white copper plate?
In our daily life, we will use a lot of metal products. Many metal products are synthetic. The white copper sheet is a copper alloy with nickel as the main alloy and no element. Based on copper-nickel alloys, cupronickel rods with third elements such as zinc, manganese, aluminum, etc. are added, ...Read more
