There are two main types of aluminum sheet that can be used to make aluminum mirror Coil:
1000 series aluminum sheet: This type of aluminum sheet is known for its high purity and good formability. It is also relatively soft, making it ideal for polishing to a mirror finish. Common 1000 series alloys used for aluminum mirror Coil include 1050, 1070, and 1085.
5000 series aluminum sheet: This type of aluminum sheet is alloyed with magnesium, making it stronger and more durable than 1000 series aluminum sheet. It is also more resistant to corrosion. Common 5000 series alloys used for aluminum mirror Coil include 5052 and 5083.
The specific type of aluminum sheet used to make aluminum mirror sheet will depend on the desired properties of the finished product. For example, if a high-strength mirror sheet is required, then a 5000 series aluminum sheet may be a better choice. If a more economical mirror sheet is required, then a 1000 series aluminum sheet may be a better choice.
In addition to the alloy type, the temper (or hardness) of the aluminum sheet is also important. For aluminum mirror Coil, a soft temper (such as O or H12) is typically used. This allows the aluminum sheet to be easily polished to a mirror finish.
It is important to note that not all aluminum sheet is suitable for use in aluminum mirror Coil applications. The aluminum Coil must be of high quality and have a smooth surface in order to be polished to a mirror finish.
