Aluminum, our daily industrial raw material is called aluminum ingot, which is obtained by smelting (or refining) and casting by alumina-cryolite by electrolysis. According to the composition content of aluminum ingots:
1. pure aluminum: aluminum content 99.93%-99.999%;
2. Industrial high-purity aluminum: The content of aluminum is 99.85%-99.90%;
3. Industrial pure aluminum: The content of aluminum is 98.0%-99.7%.

At present, the output of aluminum ingots in China is very large, and the demand is slowly increasing. The aluminum ingot industry is developing rapidly. How can we correctly judge the quality of many aluminum ingot products in the market? Let me share a few tips:
First, before purchasing aluminum ingots, first determine the model of the aluminum ingot to determine the actual work, which is an effective premise in the work process.
Second, the price factor is a project that people pay more attention to. Many people lead to theoretical judgments because of blindly obedient psychology. Therefore, we must face this problem squarely. We must look at the quality to determine the price.
Third, today's society, no matter which product has advantages and disadvantages, aluminum ingots are no exception, so we must look at the quality of the process of purchase and construction.
The buying skills of aluminum ingots have been shared with everyone, and you can purchase good quality products by mastering these points. Aluminum ingots play an important role in many fields. We also guarantee quality while producing, and consumers should also polish their eyes for purchase.

The use of color-coated plates is generally divided into three categories: construction, transportation, and home appliance casings. The color-coated plates for construction occupy a larger part, followed by the home appliance industry, and the proportion of transportation is relatively small. The color-coated plates for construction are generally made of hot-dip galvanized steel sheets and hot-dip aluminized zinc-plated steel sheets. They are mainly processed into corrugated sheets or with polyurethane sheets. They are mainly used in industrial construction and construction, airports, warehouses, freezers, etc. The roof, walls and doors of the building. The color plates of household appliances are generally based on electro-galvanized and cold plates, and are commonly used in refrigerator casings or enterprise large-scale air-conditioning enclosures, freezers, bread makers, furniture, and the like. Most of the substrates for transportation use electro-galvanized and cold plates, mainly used for oil sump and automotive interior parts.
Generally speaking, the color coated board for construction has higher strength and corrosion resistance than the color steel plate for home appliances. This is because the color coated board for construction is usually part of the stressed structure, and the working environment is located in a complex outdoor environment. The service life is also relatively long, so it is required to have high strength and corrosion resistance.

The first is the appearance, the color coated aluminum roll changes the single color of the ordinary aluminum roll surface, the coating process is defined as the color coated aluminum roll adds a lot of use chips, more colors are well interpreted on the surface of the aluminum roll material Not only is the decoration environment very good, but also the color coated aluminum coil is protected in disguise. The principle is very simple. The addition of a special organic coating on the surface of the color coated aluminum coil enhances the rust and corrosion resistance of the material, because the coating is also a special protective insulation, avoiding direct water and oxygen in the air and the metal layer. Contact, produce a chemical reaction. This point of color coated aluminum coil manufacturers is also the performance of ordinary aluminum coils.
Secondly, in the surface treatment process, compared with the ordinary aluminum coil, the surface treatment process of the color coated aluminum coil has been greatly improved, and the special adaptability of the coating makes the metal layer and the coating have better compatibility. The layer coating is disguised to compensate for the lack of surface of the metal layer. At the same time, the color coated aluminum coil is also fully optimized in the thickness treatment process, and the quality is further reduced compared with the ordinary aluminum coil.
There is still a difference between the color coated aluminum coil and the ordinary aluminum coil in terms of performance. Compared with the general aluminum coil material, the processability of the color coated aluminum coil is more outstanding, and also in the process of use. It is easier to bend and brings great convenience. At the same time, in terms of environmental adaptability, the weather resistance and high temperature resistance of the color coated aluminum coil have also been greatly improved, and the strength and scratch resistance of the material have been greatly improved. These lifting points are due to the design of the color coated aluminum coil based on the common aluminum coil and the use of unique processes.

1. Safety - Food packaging container Aluminum foil is a packaging material that can withstand high and low temperature (-20 ° C -250 ° C) molecular structure stability, it can be from the refrigerator to the oven and then to the table without the need to replace the container, compared to the current The commonly used plastic snack boxes can only withstand temperatures ranging from -16 ° C to 85 ° C. After the shiny surface of the aluminum foil is used repeatedly in the multi-function oven, the appearance is still bright, maintaining the color and taste of the food.
2. Aesthetics - The aluminum foil of the food packaging container is leakproof, strong and easy to organize. Aluminum has good conductivity and speeds up baking and freezing. Compared to other packaging materials, aluminum foil containers can restore their original appearance faster and better.

| How to control the thickness of aluminum foil |

The difficulty in controlling the thickness deviation is a feature of aluminum box rolling. The thickness difference of 3% is not difficult to control in the production of sheet and strip, but it is difficult to control in the production of aluminum foil.
As the thickness of the aluminum box is reduced, its trace conditions can affect, such as temperature, oil film, oil and gas concentration. A roll of aluminum foil can reach several hundred thousand meters, and the rolling time can be as long as about 10 hours. The error of thickness measurement is easy to form with time.
The only way to adjust the thickness of the aluminum foil is tension and speed.
These factors all contribute to the difficulty of thick control of aluminum foil rolling.
Therefore, the thickness of the actual control aluminum box is less than 3%, and many conditions are required to ensure: use of aluminum foil blanks of acceptable thickness; adjustment, control of reduction and roll type during rolling, and grinding of the rolls according to specified parameters. Stable rolling process; the thickness of the aluminum box is measured during the rolling process so as not to be found when the side thickness system fails.
