Aluminum Polishing Sheet is a special Aluminum Sheet.Its surface has been polished hence gives good performance in surface condition.The advantage of aluminum sheet is as follows:
1. Easy to process.

In 2012, the fastener industry experienced a negative growth, which was down 1.5% year-on-year, mainly due to the lack of market demand. In particular, after the fasteners suffered international anti-dumping, export sales declined. At the same time, through the integration of customs data, China's fastener import and export volume both decreased in 2012: export volume was 2.4461 million tons, and foreign exchange earned through exports reached US$4.516 billion, a year-on-year decrease of 4.8% and 2.4% respectively; fasteners import volume was 25.24%. Ten thousand tons, the import amount was 2.892 billion US dollars, down 4.7% and 2.2% respectively.
According to industry sources, although the domestic fastener industry suffered a setback in 2012, the whole industry is expected to achieve steady growth in 2013 and it is estimated that by 2013, the production and sales of fasteners will reach around 7.3 million tons. With the growth of China-ASEAN Free Trade Area, more potential free trade zones may emerge, and Chinese companies’ efforts to go abroad, China’s fastener export market is expected to further diversify, especially to emerging markets and development. The expansion of the country.
The results show that the casting aluminum alloy with good casting property or deformation aluminum alloy with good processing plasticity can be obtained by adding certain Ba Au Du element.
2. Good conductivity and thermal conductivity.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3. The density is small.
The density of aluminum and aluminum alloy is close to 2.7 g / about 1 / 3 of that of iron or copper.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
