aluminum coil sheet for sign blanks

In the products of metal signs, the proportion of aluminum signs accounts for more than 90% of the metal signs. For more than half a century, making signs with aluminum coil sheets has been enduring for a long time. The main reason is that aluminum has the most decorative expressive force. Many surface decoration technologies can be applied and played on aluminum materials, which is convenient to obtain colorful and multiple combinations of high-level decorative layers 。 On the other hand, it is determined by a series of excellent properties of aluminum coil sheet



Characteristics of aluminum: in addition to the above reasons, the physical and chemical properties of aluminum are consistent with the requirements related to the application in the label. The brief introduction is as follows.
1. The density of lightweight aluminum is 2.702gnan3, which is only 1 / 3 of that of copper and aluminum. The aluminum tag will not increase the weight of the equipment, but also save costs.
2. It is easy to process aluminum with excellent ductility, easy to cut, and easy to punch, which can meet the needs of the special process of the label.
3. Good corrosion resistance can produce hard and compact oxide film on the surface of aluminum and its alloy.
4. Good weather resistance aluminum oxide coating, many substances do not produce corrosion effect on it, and it will also have excellent durability in the harsh environment of industrial areas and coastal areas.
5. The non-magnetic aluminum is non-magnetic, and the aluminum label will not cause external interference to the instrument and equipment.
6. Rich in resources, the reserves of aluminum are considerable. The annual output of aluminum products is second only to that of iron and steel, ranking second in the total output of metal in the world
