According to the different metal elements contained in the aluminum coil, the aluminum coil can be divided into 9 categories, that is, it can be divided into 9 series.
Aluminum coil classification
1000 series
2000 series aluminum plate
Representative 2a16 (LY16) 2a06 (LY6) 2000 series aluminum plate is characterized by high hardness, of which the copper content is the highest, about 3-5%. The 2000 series aluminum sheets are aerospace aluminum and are not commonly used in conventional industries. There are fewer manufacturers producing 2000 series aluminum plates in China. The quality cannot be compared with foreign countries. Imported aluminum sheets are mainly supplied by Korean and German manufacturers. With the development of China's aerospace industry, the 2000 series of aluminum sheet production technology will be further improved.
3000 series aluminum plate
Representing 3003 3003 3a21. It can also be called rust-proof aluminum plate. China 3000 series aluminum plate production process is relatively excellent. The 3000 series aluminum plate is mainly composed of manganese. The content is between 1.0 and 1.5. It is a series with better anti-rust function. Conventional applications in the humid environment of air conditioners, refrigerators, and car bottoms, the price is higher than 1000 series, is a more common alloy series.
4000 series aluminum plate
The aluminum plate, represented by the 4a01 4000 series, is a series with a high silicon content. Typically the silicon content is between 4.5 and 6.0%. It belongs to construction materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance. Product Description: It has the characteristics of heat resistance and wear resistance.
5000 series
Represents the 5052.5005.5083.5a05 series. The 5000 series aluminum plate belongs to the more common alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%. Also known as aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than other series under the same area. Therefore, it is commonly used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industries. The processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum plate series and can be used for oxidation deep processing. In China, 5000 series aluminum plates belong to one of the more mature aluminum plate series.
6000 series
The representative 6061 contains mainly magnesium and silicon, so the advantages of the 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forged product suitable for applications requiring high corrosion resistance and oxidation resistance. Good usability, excellent interface characteristics, easy coating and good processability. Can be used on low pressure weapons and aircraft joints.
General characteristics of 6061: excellent interface characteristics, easy coating, high strength, good workability and strong corrosion resistance.
Typical uses for 6061 aluminum: aircraft parts, camera parts, couplers, marine parts and hardware, electronic parts and fittings, decorative or various hardware, hinged heads, magnetic heads, brake pistons, hydraulic pistons, electrical parts, valves and valve parts .
7000 series
The representative 7075 mainly contains zinc. Also belonging to the aviation series, it is an aluminum-magnesium-zinc-copper alloy, which is a heat-treatable alloy. It belongs to super-hard aluminum alloy and has good wear resistance. The 7075 aluminum plate is stress-relieved and will not deform or warp after processing. All super-super The thick 7075 aluminum plate is ultrasonically detected to ensure no blisters and impurities. The 7075 aluminum plate has high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is that the hardness of 7075 is a high hardness, high strength aluminum alloy, commonly used in the manufacture of aircraft structures and futures. It requires high-strength structural parts and molds with high strength and high corrosion resistance. Basically relying on imports, China's production process needs to be improved. (The company once had a foreign company proposed that the domestically produced 7075 aluminum plate is unevenly annealed, and the surface and internal hardness of the aluminum plate are inconsistent.)
8000 series
The more commonly used 8011 belongs to other series. I remember that the aluminum plate is the main function of the cap, and it is also applied to the radiator. Most of the application is aluminum foil. Not very common.
9000 series
It belongs to the spare series, and the technology is so developed. In order to cope with the appearance of aluminum plates containing other alloying elements, the International Aluminum Sheet Federation expresses that the 9000 series is a spare series, waiting for another new variety to appear to fill the gap of the 9000 series.
Drum brush is divided into long hair, medium hair, short hair three kinds, its performance is the length of the drum brush hair, rather than the thickness and length of the drum itself, brush hair is usually divided into wool and chemical fiber two kinds.
Different rollers will brush different effects, long hair rollers will brush out some fine texture, concave and convex feeling, similar to the texture effect. The paint surface after short wool roller besmear is more uniform, smooth, without concave and convex feeling, in the wool is between the two.
Roller brush is mostly made of wool and foam plastic, which can be divided into paint drum brush, hair drawing drum brush, floor paint drum brush, flat coating drum brush, etc., mainly used for large-area paint rolling in architectural decoration engineering. And can be used for coating and rolling all kinds of paint, such as: latex paint, anti-rust paint, internal and external wall paint, wallpaper glue, etc.
Note:
The use of drum brush as long as the straight brush can be wiped, if you want to daub evenly, the drum is best in the paint bucket to be fully absorbed, and then take out a few rolling on the inclined plane, press out the excess paint and then begin to brush the wall.
Low price, good quality products, to create a perfect house decoration
