Second, the characteristics of aluminum:
1. The corrosion resistance
The density of aluminum is only 2.7 g/cm3, which is about the density of steel, copper or brass (7.83 g/cm3, respectively, 8.93 g/cm3). In most conditions, including air, water, or salt water), petroleum chemistry, and many chemical system, aluminum can display excellent corrosion resistance.
2. The electrical conductivity
Aluminum is often due to its good conductivity. On the basis of equal weight, the electrical conductivity of aluminum to copper twice.
3. The amount of thermal conductivity rate
The thermal conductivity of aluminum alloy volume rate is about 50-60% of copper, the manufacturing heat exchangers, evaporators, heating appliances, cooking utensils, as well as the automobile cylinder head and radiator are very favorable.
4. The ferromagnetic
Aluminum extrusions are ferromagnetic, the electrical industry and electronic industry is an important feature. Aluminum is not spontaneous combustion, the involved in loading and unloading of or access to applications of inflammable and explosive material is important.
5. Can machine processability
Aluminum can machine processability is excellent. In deformation and aluminum casting aluminum alloy, aluminum production factory and after these alloy output with the various states, the machining features of considerable change, this will require a special machine tool or technology.
Specific tensile strength, yield strength, extensibility and corresponding work hardening rate dominates the allows the change of the deformation.
7. Recycling sex
Aluminum has a very high recovery, the properties of the recycled aluminum and primary aluminum almost no difference.
Aluminium profile of these qualities, for it can be used as the following purposes:
Including building Windows and doors curtain wall aluminum extrusions, aerospace, transportation, use aluminum, CPU radiator
