Now the aluminum tube profiles have used in a lot of area, such as aviation, industrial, medical, etc. The aluminum tube profiles have a lot of physical properties that will talked in the rest articles.
The recommended reasons for aluminum tube profiles will contain the following:
The density of aluminum tube profiles
The strength of the aluminum tube profiles
The corrosion resistance of aluminum tube profiles
Thermal conductivity of aluminum tube profiles
The conductivity of aluminum tube profiles
The reflectivity of aluminum tube profiles
Mechanical properties of aluminum tube profiles
Aluminium is about a third as dense as steel or copper, making it one of the lightest commercially available metals. The resulting high strength-to-weight ratio makes it an important structural material, especially in the transportation industry, that can increase the payload or save fuel.
Pure aluminum tube profiles does not have high tensile strength. However, the addition of alloying elements (such as manganese, silicon, copper and magnesium) can increase the strength of aluminum tube profiles and produce alloys with properties suitable for specific applications.
Aluminum is perfect for cold environments. Its advantage over steel is that its tensile strength increases with decreasing temperature while retaining its toughness. On the other hand, the steel will becomes brittle at low temperatures.
When exposed to air, a layer of alumina forms almost immediately on the surface of the aluminum tube profiles. The layer has excellent corrosion resistance. It is quite resistant to most acids, but less resistant to bases.
The thermal conductivity of aluminum tube profiles is about three times that of steel. This makes aluminum an important material for cooling and heating applications such as heat exchangers. This, combined with its non-toxic nature, means aluminium is widely used for cook.
Aluminium together with copper has a high conductivity sufficient to be used as an electrical conductor. Although the commonly used conducting alloy (1350) is only 62 % as conductive as annealed copper, it weighs only a third as much, so it is twice as conductive as copper of the same weight.
Aluminum tube profiles is an excellent reflector of radiant energy from ultraviolet to infrared rays. Visible light has a reflectivity of about 80%, meaning it is widely used in lamps. Reflectivity has the same properties, making aluminum tube profiles an insulating material that prevents direct sunlight in summer and heat loss in winter.
Aluminum tube profiles can be seriously deformed without failure. This allows aluminum tube profiles to be formed by rolling, extrusion, drawing, machining and other mechanical processes. It can also be cast to high tolerances.
Alloying, cold working and heat treatment can all be used to adjust the properties of aluminum tube profiles.
The tensile strength of pure aluminum is about 90 MPa, but can be increased to over 690 MPa for some heat-treatable alloys.
