What is Polished aluminum plate? from Gu's blog

Polished Aluminum is a type of aluminum which has undergone a process called anodization, which changes the appearance of aluminum and makes it non-magnetic or made from a different conductivity. This is done to prevent corrosion by forming a layer of oxide on the surface.

The most common form for polished aluminium is 5086 aluminium sheet that has been anodized in blue and 9064 that has been anodized in black. And normally 6061 alloy contains about 1% copper whereas 9064 alloy contains only .07% copper. The price of polished aluminum plate depends on its size,  In terms of sheet, the price ranges from $1 to $15 per linear foot according to size and quality. In case of round bar, the cost is between $2 and $20 per pound. These prices can vary greatly depending on supplier and grade.

The coating or oxide layer that forms on aluminum during its anodization process gives polished aluminum a mirror-like finish. This makes it very reflective because light reflects off of the surface in a number of different directions instead of bouncing back into your eyes like it does on other metals such as steel or plastic. As  a result, polished aluminum is commonly used for windows, automobiles and other vehicles because it reflects up to 99% of the light that hits it.

Aluminum is non-magnetic but when anodized aluminum goes through a process called magnetization reversal, its surface becomes magnetic again. This means that if you rub a piece of polished aluminum with paper, you will get smudges on your paper. However if you rub the same piece of Aluminium Checkered Plate against cloth or another material which has “a higher permeability” than the cloth or material used in rubbing then this technique can be used to remove some of the oxide coating without damaging the underlying metal.

Polished Aluminum has many unique properties making it ideal for use in any application where durability and reflection are important characteristics such as windows, mirrors, airplanes and boats; It also withstands weathering well therefore eliminating corrosion issues from its applications like aircrafts and buildings etc.
