which industries are the aluminum circle discs usually applied in?
In the daily life , we can often see aluminum products, maybe you do not know it, but aluminium alloy sheet has brought great convenience to our lives:aluminium circle for cookware, aluminum circles for crafts,aluminium circle for traffic sign,ect. aluminum circle discs and aluminum alloys are often used as forgings in industry, Can be cast a variety of shapes and varieties of forgings, and can use a variety of ways to connect, including the use of welding, welding and other welding methods can also use the bonding and riveting and bolting of this mechanical approach to convergence. In addition it, aluminum heaters are often used to melt refractory metals and welded rails, and can also be used as a deoxidizer in the process of steel making.

The most significant feature of aluminum circle discs is the weight of aluminum metal  sheet and the ability to resist corrosion. Its density is small, light weight, so in the aviation, automobile, ship and other transportation manufacturing industry widely. In addition, the spacecraft, artificial satellites and other high-tip industries also use a lot of aluminum discs, aluminium alloy sheet plate and aluminum.

Aluminum round circles metal in the electrical manufacturing industry, wire and cable and the radio industry has a very wide range of uses. This is because it has excellent electrical conductivity. Its conductivity is weaker than gold, silver and copper, but because of its large reserves, and the density is small, only equivalent to one-third of copper, so the same amount of electricity, aluminum quality is only Half of copper. In addition, the surface oxide film of aluminum has not only the ability to resist corrosion but also a certain insulation.
