Among metal sign products, the proportion of aluminum signs accounts for more than 90% of metal signs. For more than half a century, the use of aluminum plates to make signs has been enduring. The main reason is that aluminum has the most decorative performance. Power, many surface decoration processes can be applied and played on aluminum, which is convenient to obtain colorful, various combinations of advanced decorative layers. On the other hand, it is determined by a series of excellent properties of aluminum.
The 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 sign.
1. Light weight The density of aluminum is 2.702gNaN3, which is only 1/3 of that compared with copper and aluminum. The aluminum label will not increase the weight of the equipment and save costs.
2. Easy to process Aluminum has excellent ductility, is easy to cut, and is also easy to stamp. It can meet the needs of special technology for signage.
3. Good corrosion resistance. Hard and dense oxide film can be formed on the surface of aluminum and its alloy.
4. Good weather resistance Aluminum oxide film layer, many substances do not have a corrosive effect on it, it will also have excellent durability in the harsh environment of industrial areas and coastal areas.
5. Non-magnetic Aluminum is a non-magnetic body, and aluminum signs will not cause external interference to the equipment.
6. Abundant resources Aluminium reserves are considerable. The annual output of aluminum products is second only to steel, ranking second in the world's total metal output.
