At present, the raw materials of electronic products are no longer relying solely on copper strip. Because the conductivity of aluminium is only lower than that of copper, the replacement of copper strip by aluminium strip is becoming a popular trend in the world.
Aluminum strip is a deep-processed product of aluminium formed by cutting aluminium coil. It is an important raw material in industry.
According to the different alloying elements contained in the aluminium strip, the aluminium strip and the aluminium sheet are also divided into 8 series. However, the most commonly used series are 1000, 3000, 5000 and 8000 series.
According to the different annealing state of the aluminium strip, the aluminium strip can be divided into full soft (o) / semi-hard (H24) / full hard (h18). At present, the most commonly used should belong to the full soft series, because the O state aluminum strip is easier to stretch and bend.
The main processing equipment of aluminium strip is the slicing unit, which can be divided into the required length and width according to the need. Of course, the strip processing equipment is universal, but also for copper coil processing, the products processed are called copper strips.
The alloy grades of commonly used aluminium strips are 1050, 1060, 1070, 1100, 3003, 3004, 5005, 5052, 8011, etc. Common states are O and H states. O denotes soft state, H denotes hard state. After O and H, the degree of hardness, softness and annealing can be expressed by numbers.
Specific uses of aluminium strip include transformer aluminium strip (transformer aluminium foil), high frequency welding hollow aluminium strip, fin radiator aluminium strip, cable aluminium strip, stamping aluminium strip, aluminium edge strip, etc.
The categories of aluminium alloy strips are pure aluminium strips, transformer aluminium strips, superhard aluminium strips, all-soft aluminium strips, semi-hard aluminium strips and anti-rust aluminium strips.
