Aluminum Classification by Use:

1. Architectural aluminum profiles: window and door profile and curtain walls profile.

2. Heatsink aluminum profile.

3. General industrial aluminum profile: it is mainly used for industrial production and manufacturing, such as automatic mechanical equipment, the framework of the cover and the customized mould according to the requirements of each company's mechanical equipment.

4. Aluminum alloy profile for rail vehicle structure: it is mainly used in the manufacturing of rail vehicle body.

5. Mounting aluminum profiles, making various aluminum alloy picture frames and using for mounting various exhibitions and decorative paintings.

The Characteristic of Aluminum Profile:

1. Corrosion Resistance:

The aluminum profile has a density of about 2.8g/cm3, the density is about a third of steel, copper or brass. Aluminum exhibits excellent corrosion resistance under most environmental conditions, including in the air, water, petrochemical and many chemical systems.

2. The Electrical conductivity:

Aluminum profiles are often used because of their excellent electrical conductivity. Aluminum conducts nearly twice as much electricity as copper under the same weight.

3. Thermal conductivity:

The thermal conductivity of aluminum alloy is about 50-60% that of copper, which is very beneficial for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, as well as automobile cylinder heads and radiators.

4. Non-ferromagnetism:

Aluminum profiles are non-ferromagnetic, an important property for the electrical and electronic industries.

5. Machinability:

Aluminum profile machinability is very good, is better than many of the same industrial building materials.

6. Formability:

Specific tensile strength, yield strength, ductility and the corresponding workhardening rate govern the allowable deformation. Various investigations have shown that the rating of the formability of commercially available aluminum profiles in different shapes depends on the forming process.

7. Recycling:

Aluminum is highly recyclable and its properties are almost indistinguishable from those of primary aluminum.

Aluminum Profile Production Process:

Mainly including casting, extrusion and coloring (Coloring mainly includes: oxidation, electrophoresis coating, fluorocarbon spraying, powder spraying, wood grain transfer, etc.) three processes.

1. Melting is the first process of aluminum profile production

The main process:

(1) Ingredients: According to the specific alloy brand to be produced, calculate the amount of addition of various alloy components, and reasonably match various raw materials.

(2) Melting: The prepared raw materials are added into the melting furnace to melt according to the process requirements, and the impurities and gases in the melt are effectively removed by means of degassing and slag removal refining.

(3) Casting: Molten aluminum is cooled and cast into round bars of various specifications through deep well casting system under certain casting process conditions.

2. Extrusion:

Extrusion is the means of forming profiles. Firstly according to the profile product section design, manufacture the mold, use the extruder to extrude the aluminum bar from the mold to the profile. The normally used alloy is 6063 alloy there is also an air-cooled quenching process and subsequent manual aging process during extrusion to complete the heat treatment strengthening. The heat treatment system of different grades of heat treatable alloy is different.

3. Coloring (The anodizing process is mainly discussed here)

Anodizing: the extruded aluminum alloy profile has a weak corrosion resistance on its surface. The surface treatment must be carried out through anodic oxidation to increase the corrosion resistance, wear resistance and appearance of the aluminum. High compartment aluminum plant production of high compartment aluminum is almost all oxidized.
