The raw materials of the Aluminium coil are pure Aluminium or Aluminium alloy cast rolled Aluminium coil and hot rolled Aluminium coil, which are rolled into a thin Aluminium coil with different thickness and width by a cold rolling mill, and then longitudinally cut into Aluminium coil with different width by longitudinal shear according to the purpose. Today, I'd like to talk about some related knowledge about the Aluminium coil. Do you know its classification and brand status? What is the processing technology? Now let's learn about it.

Classification Grade Status Of Aluminium Coil

The categories of Aluminium alloy strip are: pure Aluminium coil, transformer Aluminium coil, super hard Aluminium coil, full soft Aluminium coil, semi-hard Aluminium coil, antirust Aluminium coil; the Aluminium coil is mainly divided into transformer Aluminium coil (transformer Aluminium foil), Aluminium coil for high-frequency welding hollow Aluminium strip, Aluminium coil for fin radiator, Aluminium coil for cable, Aluminium coil for stamping, Aluminium coil for Aluminium edge strip, etc. The commonly used alloy grades of the Aluminium coil are 1050, 1060, 1070, 1100, 3003, 3004, 5005, 5052, 8011, etc. The common states are o state and H state. O is the soft state and H is the hard state. O and h can be followed by numbers to indicate the degree of hardness and hardness, and the degree of annealing.

Processing Technology Of Aluminium Coil

Aluminium coil is a deep-processing product formed by Aluminium coil cutting. It is an important raw material in the industry. According to the different alloy elements contained in the Aluminium coil, the Aluminium coil is the same as the Aluminium plate and can be divided into 8 series. However, the commonly used series are 100030005000 and 8000. According to the annealing state of the aluminium tube, the Aluminium coil can be divided into all soft (o state), half-hard (H24), and all hard (h18). At present, the most commonly used ones should belong to the full soft series, because the o-state is easier to stretch and bend.

The aluminium coil's main processing equipment is a slitting machine, which can be divided into the required length and width according to the needs. Of course, the equipment for strip processing is universal, and it can also process the copper coil. The processed product is called a copper strip. At present, the raw materials of electronic products are no longer purely dependent on copper strips in the world. Because the conductivity of Aluminium is only lower than that of copper, the Aluminium coil is becoming a popular trend in the world to replace copper strip. To sum up, the Aluminium coil is an important raw material in the industry. It has many kinds, wide uses, and advanced processing technology. It has gradually replaced copper strip in the development of electronic products.

Five Reasons Why Aluminium Coil Must Be Used

The main reason is: because of the existence of Aluminium in the copper Aluminium transition terminal a, the defects and deficiencies of Aluminium still exist, especially the compressive creep performance. If this kind of terminal is used to connect the Aluminium coil, the advantages and value of the Aluminium coil are fully reflected. It is better to directly use the Aluminium coil because the Aluminium coil is more economical. The advantage and value of the Aluminium coil can be brought into full play by using Aluminium alloy special copper Aluminium terminals.

The second reason: the copper Aluminium transition terminal was originally used to connect Aluminium coil and copper mechanical equipment. The resistance value of copper Aluminium terminal installation size does not match the resistance value of terminal equipment size, which not only increases the conductivity and compressive creep performance between copper mechanical equipment but also increases the electrical performance and the copper multi-channel connection, It will also leave a connection security risk. The use of Aluminium alloy terminals can avoid similar problems.

The third reason: due to the mismatch between the copper Aluminium transition connection terminal and the electrical terminal, increasing the conductivity and compressive creep performance of the copper mechanical equipment, which often leads to the cost contradiction, it is difficult to avoid the connection safety hidden danger caused by the barbaric construction. Similar problems can be avoided by using the special copper Aluminium terminal of Aluminium alloy.

The fourth reason: because the copper Aluminium transition terminal was originally used to connect Aluminium coil, the inner diameter of the terminal does not match the outer diameter of the cable conductor, so special crimping tools must be used, which makes it difficult to standardize the construction and leaves hidden dangers for connection safety. The use of Aluminium alloy terminals can avoid similar problems.

The fifth reason: among the various brands of copper Aluminium transition terminals currently used in the market, the purity of Aluminium can only reach 99.5% (Note: the purity of general electrical Aluminium is above 99.7%). Moreover, the Aluminium used in the manufacture of copper Aluminium transition terminals is the industrial Aluminium with relatively poor conductivity after solid melting and quenching treatment, so the comprehensive conductivity of these copper Aluminium transition terminals can only be below 54% IACS (Note: the conductivity of conductor Aluminium alloy is required to be above 61% IACS), which causes the electrical performance mismatch between the terminals and Aluminium coil, resulting in the increase of the resistivity of the transmission line by more than 21%, The transmission capacity of the line decreases by 21% or the line loss increases by more than 21%. Using Aluminium alloy special copper Aluminium terminal can give full play to the power transmission ability of Aluminium coil.

As for other Aluminium alloy terminals with different properties from aa-8000 conductor Aluminium alloy, due to the differences between their physical, mechanical, electrical, compressive creep properties and aa-8000 conductor Aluminium alloy properties, it is self-evident that if such terminals are used for Aluminium coil connection, the hidden safety problems will be brought.

Therefore, users and relevant industry personnel must clearly understand the fact that:

To ensure that the advantages and values of the Aluminium coil can be brought into full play and reflected, the premise of safe and hidden danger-free application of Aluminium coil is that Aluminium coil meeting the requirements of the standard can be used together with supporting Aluminium alloy soft state special copper Aluminium terminals consistent with the performance of the cable.
