Aluminum for construction,Aluminum for building construction products made of aluminum and aluminum alloy materials. It is usually processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc.Aluminum for building and then cold bending, sawing, drilling, assembling, and coloring.
Pure aluminum has low strength and its use is limited. However, by adding a small amount of one or several alloying elements, such as magnesium, silicon, manganese, copper, zinc, iron, chromium, titanium,Aluminum for building etc. aluminum alloys with different properties can be obtained. The aluminum alloy is further strengthened and hardened by cold working and heat treatment, and its tensile strength is greatly improved.
The standard potential of aluminum is -1.67 volts,Aluminum for building and its chemical properties are very active. It is easy to react with oxygen in the air to form a firm and dense oxide film. Therefore,Aluminum for building aluminum has good corrosion resistance in ordinary atmosphere and clean water.
However, galvanic corrosion will occur when it comes in contact with steel or other metal materials. It will corrode when it comes in contact with alkaline materials such as concrete,Aluminum for building cement mortar and lime in a humid environment, and it will also corrode when it comes in contact with wood and soil. Therefore,Aluminum for building proper anti-corrosion treatment is required.
