5xxx seri white aluminum coil stock

5xxx seri white aluminum coil stock contributes a lot to making up marine sheet metal parts like tanks of liquefied natural gas tankers. Speaking of marine structures people tend to picture large frames in their mind’s eye. Because of its good anti-rust property 5xxx seri aluminum coil sheet takes up the largest share of raw material for tankers and vessels.

Exposed to all kinds of severe conditions like rain, snow, seawater, sea air, petrol and changing moisture degrees, marine tanks are easily subject to corrosive medium. In this case white coil stock aluminum, commonly 5xxx which is renowned for excellent corrosion resistance against sea conditions, is put into good use. Although stainless steel can compete 5xxx seri aluminum coil stock in this aspect, it’s much more expensive than the latter. In addition, disqualified steel may get oxidized, which will never occur to coil stock aluminum, because when aluminum gets oxidized, aluminum oxidize is produced. Aluminum oxidize, with extraordinary stability, acts as a protective cover that prevents the inner part from being further oxidized. In this way, the whole marine tank becomes a corrosion resistant body.

The reason why 5xxx aluminum alloy boasts exceptional anti-corrosion property is that it’s an alloy containing magnesium. Magnesium has good weather resistance ability, and after it being combined with aluminum, this favorable ability is kept. Except for marine structures, 5xxx white coil stock aluminum is also applicable in aircraft, building and electronic industries. Products like oil tanks of planes, security doors and tread plates are familiar to us. No matter whether you are aware of it or not, coil stock aluminum is guarding your life.
