Copper Silica Sol Investment Casting
It can be said that there are many reference standards for copper castings, and there are different series, such as national standard, American standard, European standard and so on. Specifically, the national standard is mainly GB/T1176-1987, the American standard is ASTM B505, and the European standard is BS EN 1982-2008.
The formula of Copper Silica Sol Investment Casting is: adding a small amount of deoxidizing elements or other elements to improve the material and performance, so it is also classified as copper alloy. Chinese copper processing materials can be divided into: ordinary copper (T1, T2, T3, T4), oxygen-free copper (TU1, TU2 and high-purity, vacuum oxygen-free copper), deoxidized copper (TUP, TUMn), adding a small amount of alloy Elements of special copper (arsenic copper, tellurium copper, silver copper) four categories.

If you are not familiar with copper castings in castings, then you can gradually understand and understand this kind of castings through the previous related articles, so as to continuously increase the professional knowledge in this area. Next, in order to continue this work and at the same time, promote the learning process of this product, we will continue to introduce the website product of copper castings, the specific content of which is as follows.
1. Are there many reference standards for copper castings?
It can be said that there are many reference standards for copper castings, and there are different series, such as national standard, American standard, European standard and so on. Specifically, the national standard is mainly GB/T1176-1987, the American standard is ASTM B505, and the European standard is BS EN 1982-2008. However, no matter which standard series it is, the mechanical properties of copper castings are similar.
2. During the production process of copper castings, if there are pores inside, will it affect the casting quality and the casting quality?
This problem, in the view of Qinhuangdao Zhongwei Precision Machinery Co., Ltd., a copper casting manufacturer, is certain and certain. Because, if there are pores inside, it means that there is air inside the material, and it has not been drained cleanly. At this time, if it is not treated, it will affect the quality of casting and castings. For example, on the surface of copper castings, there will be Honeycomb-shaped pores.
3. Is the copper casting in the copper casting more difficult to manufacture than the ordinary casting?
The red copper castings in the copper castings, in terms of raw materials, are red copper, which is a kind of copper element, and is a kind of industrial pure copper. Because its color is purple-red, it is called red copper. And its casting difficulty, from a professional point of view, is indeed more difficult than ordinary copper castings, so the answer to this question is yes.
Qinhuangdao Zhongwei Precision Machinery Co., Ltd. has been focusing on one-stop supply chain services for wear-resistant copper sleeves for more than 20 years, and can provide one-stop services from product development, production, processing, technical consultants, sales and independent brands. Main products: copper sleeves, copper lining tiles, copper slide plates, copper nuts, copper worm gears, copper sliders and other copper alloy products casting and processing.

Application
Application of Copper Silica Sol Investment Casting in Electricity
Power transmission requires a large amount of high-conductivity copper, which is mainly used for power wires and cables, bus bars, transformers, switches, plug-in components and connectors.
In the transmission process of wires and cables, electric energy is wasted due to resistance heating. From the point of view of energy saving and economy, the ""best cable cross section"" standard is currently being promoted in the world. In the past, the popular standard was purely from the perspective of reducing the investment of one installation, in order to minimize the cable cross-section, so as to avoid dangerous overheating under the rated current required by the design, to determine the minimum allowable size of the cable. Cables laid according to this standard, although the installation cost is low; but in the long-term use process, the resistance energy consumption is relatively large. The ""best cable cross section"" standard takes into account the two factors of one-time installation cost and power consumption, and appropriately enlarges the size of the cable to achieve the purpose of energy saving and the best comprehensive economic benefit. According to the new standard, the cross-section of the cable is often more than doubled compared to the old standard, and the energy saving effect of about 50% can be obtained.
In the past period of time, due to the shortage of steel in my country, considering that the proportion of aluminum is only 30% of that of copper, measures have been taken to replace copper with aluminum in overhead high-voltage transmission lines that hope to reduce weight. underground cables. In this case, aluminum is dwarfed by the disadvantages of poor electrical conductivity and larger cable size compared to copper.
For the same reason, it is also a wise choice to replace the old aluminum winding transformer with an energy efficient copper winding transformer.
