Leaded brass tube processing requirements
First of all, leaded brass tube before processing can not have cracks, distortion, not round deformation, in the factory had made a defect mark, before processing must ensure the inner surface of clean, no water no oil. Secondly, the processing of the pipeline is processed in accordance with the ...Read more -
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 -
Control method of surface quality of copper busbar
Surface quality control is the whole process of copper busbar production to product packaging control, is a fine management, careful operation of the system engineering, each process is the key to control product surface quality. The quality of billet surface is greatly affected by whether the co...Read more -
Influencing factors of copper busbar surface quality
Copper busbar products are mainly used in power, electronics, communication, heat dissipation, mold and other industries. With the development of national economy and the increasingly fierce market competition, users have higher and higher requirements on the surface quality of copper bus product...Read more -
Seamless brass tube with good performance characteristics
Seamless brass tube this product in today’s daily life application is more common, many places will use this product. But even with such a common product, there are still many people who are not particularly familiar with its performance characteristics. Then, the following is a brief intro...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 -
Some knowledge about bearings
Aluminum bronze can be used to produce bearing related products. [Standard bearing]: The inner diameter or outer diameter, width (height) and size of the standard bearing conform to the bearing shape specified in GB/T 273.1-2003, GB/T 273.2-1998, GB/T 273.3-1999 or other relevant standards size. ...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 -
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 is the main purpose of white copper? How can it be distinguished from silver?
We use a lot of metals in our lives, and there are metals in various products. White copper is a copper-based alloy with nickel as the main added element. It is silver-white and has metallic luster, so it is named cupronickel. Copper and nickel can be infinitely dissolved in each other, thus form...Read more
