In the metal signs of the product, the proportion of aluminum plate, about 90% of the metal signs, more than half a century, with aluminum plate production signs, has been enduring, the main reason lies in the most decorative performance of aluminum, many surface decoration technology, can be used on aluminum and play, easy to obtain colorful, A variety of combinations of advanced decorative layer. On the other hand, it is decided by the excellent properties of the aluminum material.
Aluminum Characteristics: In addition to the above reasons, the physical and chemical properties of aluminum and signs in the application of the relevant requirements are consistent, are described below.
1. Light weight aluminum density is 2.702gnan3, compared with copper and aluminum only for its 1/3, aluminum plate will not increase the weight of equipment, but also save money.
2. Easy to process aluminum ductility, easy to cut, but also easy stamping forming, to meet the needs of special signs of the process.
3. Corrosion resistance on the surface of aluminum and its alloys can produce hard and dense oxide film.
4. Good weatherability Aluminum Oxide film layer, many substances do not have a corrosive effect on the industrial areas of harsh environment and coastal use will have excellent durability.
5. No magnetic aluminum is non-magnetic, the aluminum plate will not produce external interference to the equipment.
6. Resource-rich aluminum reserves are considerable, the annual output of aluminum products next to steel, the world's second largest metal production.
