Top 10 Properties of Aluminum
As one of the leading Chinese aluminum sheet suppliers, Sino East Group always shares some knowledge about aluminum and aluminum sheet products. Today, we are going to share top 10 properties of aluminum.
1. Corrosion Resistance
The density of aluminum is only 2.7g/cm³, about 1/3 of the density of steel (7.83g/cm³), and copper or brass (8.93g/cm³). In most environmental conditions, including air, water (or salt water), petroleum chemistry and many chemical systems, aluminum can show excellent corrosion resistance.
2. Reflex
The surface of aluminum has a high degree of reflection. Radiation, visible light, radiant heat and waves can be effectively reflected and aluminum surface of anodic oxidation and dark anodic oxidation can be reflective and absorptive. Polished aluminum has superior reflectivity in a wide wavelength range, so that it can be used on various decorative and reflective purposes.
3. Conductivity
Aluminum is often chosen for its excellent electrical conductivity. On the basis of equal weight, the electrical conductivity of aluminum is nearly two times as much as that of copper.
4. Thermal Conductivity
Aluminum alloy thermal conductivity is about 50-60% of copper’s, which is good for manufacturing the heat exchanger, evaporator, heating appliances, cooking utensils, and car cylinder head and radiator.
5. Non-ferromagnetic
Aluminum is not ferromagnetic, which is an important characteristic for the electric and electronics industry.
6. Non-spontaneous
Aluminum is not spontaneous. it is important for the application of loading and unloading or contacting with inflammable and explosive materials.
7. Machinability
The machinability of aluminum is premium. In a variety of wrought aluminum alloys and cast aluminum alloys, and the state of these alloys finishing output, the machining characteristics changes a lot, which requires special machine tools or technology.
8. Formability
This is one of the most important properties of aluminum and many aluminum alloys. The specific tensile strength, yield strength, ductility, and the corresponding rate of work hardening govern the change of the deformation amount. The rated value of formability of the commercially available aluminum alloys in different shapes depends on the forming process. These rated values can just serve as a general guide in the qualitative comparison of the metal processing properties, that is, they can not be used as the extreme value of formability.
9. Malleability
Aluminum alloys can be forged into forgings with a wide variety of shapes and species, and their selection range of the final component forging design criteria (based on intended use) are wide. There are many methods of jointing aluminum, including welding, resistance welding, brazing, soldering and bonding as well as riveting and bolting mechanical methods.
10. Recyclability
Aluminum has a very high recyclability; the characteristics of recycled aluminum and primary aluminum are almost no different.
