Aluminum strip refers to aluminum sheet or aluminum strip made of aluminum as the main raw material and mixed with other alloying elements. Aluminum strip is an important material for China’s national economic development and is widely used in aviation, aerospace, construction, printing, medicine and other industries. The aluminum strip has good light reflectivity, and the surface of the aluminum strip is bright and flat, and the reflective performance is stronger. The purity of the aluminum raw material has a significant effect on the reflectivity of the aluminum foil. When there is an impurity in the aluminum foil, impurity scattering occurs to increase the radiation absorption.
Aluminum strip has an extremely wide range of applications and is an aluminum deep-processed product formed by aluminum coil slitting. It is also an important raw material in the industry. The aluminum strip needs to have good formability and high corrosion resistance but does not require high-strength part parts. Aluminum is a silver light metal with ductility. Commodities are often made into columnar, rod, flake, foil, powdery, banded and filamentous, forming a layer of oxide film to prevent metal corrosion in moist air.
Electronics is playing an ever-increasing role currently. Copper is not the only choice as the raw material in electronics. In comparison to aluminum copper is heavy and expensive. Aluminum stripto replace copper strip as a raw material in electronics is becoming an international trend.
Transformers using aluminum strip winding have advantage of small size, light weight, good insulation properties, flame retardant, non-polluting, partial discharge, resistant to moisture, smooth and reliable operation, low noise, and low maintenance cost.In dry type transformers, aluminum winding have been commonly used.
The weight and strength of the aluminum strip can be improved by cold working. The aluminum can be cast by any casting method and can be processed by various machine tools. The corrosion resistance of aluminum alloy can be improved by adopting protective measures. After the longitudinal shear machine components cut into the required width of aluminum strip. Used in the manufacture of aircraft fuel tanks, oil pipes, as well as transportation vehicles, sheet metal parts for ships, hardware products, etc. The raw material of the aluminum strip is a pure aluminum or aluminum alloy cast aluminum coil, hot rolled aluminum coil, which is rolled into a thin aluminum coil of different thickness and width by a cold rolling mill.
The aluminum strip of armored cable is widely used in the armored layer of cable. The temper is O state, H18, H24 and other common states. It plays a very important role in protecting the security of power and communication. Many structures are capable of adding armor layers, which can be laid in a variety of ways. When adding metal, you should first observe the laid environment. The aluminum strip of armored cable is made of certain alloy, which can well meet the needs of armored layer.
Aluminum circles are also ubiquitous in our lives, such as the outer casings of various home appliances in our lives, as well as a variety of electronic products and automotive products, etc. The weight and strength of the aluminum strip are not high. Although the strength of pure aluminum is not high, it can be doubled by cold working, and further strengthened by heat treatment by adding alloying elements, the strength of which is comparable to that of high-quality alloy steel. Aluminum is easy to process and aluminum can be cast by any casting method.
AT ISSUE There is a common misconception that a distribution transformer with copper windings is in some way more efficient, more reliable, or has higher short circuit strength when compared to a transformer with aluminum windings.
Reactor is a kind of electromagnetic device which uses electromagnetic induction principle to transfer energy and information in the electric appliance. Its material consists of four kinds: 1. magnetic material 2. conductive material 3. insulating material 4. structural material.
As a aluminum strip manufacturer, Haomei Aluminum found that water the main culprit of corrosion of coated aluminium strip during storage and transportation, whether annealing state or hard state, as long as water or affected with damp, any kind of packaging way will suffer corrosion. The water corrosion has a characteristic, namely in the surface of aluminium strip, there is a white watermark corrosion boundaries, area under the influence of water with large area of corrosion state and no obvious directivity. There is no obvious watermark corrosion boundary in the complex form of damp corrosion.
