Classification of industrial aluminum profiles according to surface treatment requirements

1. Anodized aluminum

6. Planed aluminum (divided into mechanical planing and chemical polishing, of which chemical polishing has the highest cost and the most expensive)

Classification of industrial aluminum profiles by alloy
Can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and other alloy grade aluminum profiles, of which the 6 series are the most common. The difference between different grades is that the proportion of various metal components is different, except for commonly used door and window aluminum profiles. Such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other architectural aluminum profiles, there is no clear model distinction of industrial aluminum profiles, most production plants are processed according to the customer's actual drawings.

Characteristics of industrial aluminum profiles
Corrosion resistance
The density of aluminum profile is only 2.7g / cm3, which is about 1/3 of the density of steel, copper or brass (7.83g / cm3, 8.93g / cm3 respectively). Under most environmental conditions, including air, water (or brine), petrochemicals, and many chemical systems, aluminum can show excellent corrosion resistance.
Conductivity
Aluminum profiles are often chosen for their excellent electrical conductivity. On an equal weight basis, the electrical conductivity of aluminum is nearly twice that of copper.
Thermal conductivity
The thermal conductivity of aluminum alloy is about 50-60% of copper, which is beneficial for manufacturing heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.
Non-ferromagnetic
Aluminum profiles are non-ferromagnetic, which is an important feature for the electrical and electronics industries. Aluminum profiles are not self-igniting, which is important for applications involving handling or contact with flammable and explosive materials.
Machinability
The machinability of aluminum profiles is excellent. In various deformed aluminum alloys and cast aluminum alloys, and in the various states that these alloys have after production, the machining characteristics vary considerably, which requires special machine tools or techniques.
Formability
Specific tensile strength, yield strength, ductility, and corresponding work hardening rate govern changes in the amount of deformation allowed. According to Foresight.com's "2013-2017 China Aluminum Profile Industry Segmented Product Production and Sales Demand and Prospect Forecast Analysis Report" survey, the commercially available aluminum profiles in different forms of formability ratings depend on the forming process method.
Recyclability
Aluminum has extremely high recyclability, and the characteristics of recycled aluminum are almost the same as those of primary aluminum.
