Aluminum Profile

Aluminum profile is a common material in social production. It has a wide range of uses in aviation, construction, condenser, auto parts, and other industries. Its excellent performance and many advantages are favored by the majority of industries. Ganghua (Shandong) Iron Steel Co., Ltd. sells and operates aluminum plates, aluminum tubes, aluminum profiles, 8020 aluminum profiles, architectural aluminum profiles, heat dissipation profiles, industrial profiles, aluminum T profiles, and 4040 aluminum profiles. Support various profiles customization, welcome to contact us.

The aluminum profile is a process material that chemically treats the activated plated parts in an aqueous solution of salt and hydrochloric acid. Aluminum profiles are often selected due to their excellent electrical conductivity. On an equal weight basis, aluminum's electrical conductivity is nearly twice that of copper, and its thermal conductivity is about 50%-60% that of copper, which is useful in the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobiles. The cylinder head and radiator are very beneficial. Aluminium profiles are non-ferromagnetic, an important property for the electrical and electronic industries. The non-self-igniting property of aluminum profiles is important for applications involving handling or contact with flammable and explosive materials. Aluminum profiles also have extremely high recyclability, and the characteristics of recycled aluminum are almost the same as those of primary aluminum.

It has stable chemical properties, non-magnetic, and can be recycled and reused. It is a benign and recyclable metal material.

The elastic coefficient is small, and there is no spark in collision and friction, which is the best in automotive technology.

Resistance to nuclear radiation.

No metal pollution, no toxicity, no volatile metals in the surface oxide layer.

It has good thermal conductivity and electrical conductivity, and has outstanding performance in short-distance power transmission.

Characteristics Of Aluminum Profiles

1. Non-ferromagnetic

Aluminium profiles are non-ferromagnetic, an important property for the electrical and electronic industries. Aluminum profiles are not self-igniting, which is important for applications involving handling or contact with flammable and explosive materials.

2. Machinability

The machinability of aluminum profiles is excellent. In various wrought and cast aluminum alloys, and in the various states in which these alloys are produced, the machining characteristics vary considerably, which requires special machine tools or techniques.

3. Formability

The specific tensile strength, yield strength, ductility and corresponding work hardening rate govern the variation in allowable deformation.

4. Recyclability

Aluminum is extremely recyclable, and the properties of recycled aluminum are almost indistinguishable from virgin aluminum.

5. Corrosion resistance

The density of aluminum profiles 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). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including in air, water (or brine), petrochemicals, and many chemical systems.

6. Conductivity

Aluminum profiles are often chosen due to their excellent electrical conductivity. On an equal weight basis, the conductivity of aluminum is approximately 1/2 that of copper.

7. Thermal conductivity

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

Product Classification And Application

By purpose

1. Architectural aluminum profiles (divided into doors and windows and curtain walls).
2. Radiator aluminum profile.
3. General industrial aluminum profiles: mainly used for industrial production and manufacturing, such as automated machinery and equipment, the skeleton of the cover, and the mold opening according to your own needs.
4. Aluminum alloy profiles for rail vehicle structure: mainly used in the manufacture of rail vehicle body.
5. Mounting aluminum profiles, making aluminum alloy picture frames, mounting various exhibitions and decorative paintings.

By alloy composition

It can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and other alloy grade aluminum profiles, of which 6 series are the most common. The difference between different grades is that the ratio of various metal components is different. Such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other architectural aluminum profiles, there is no clear model distinction for industrial aluminum profiles, and most of them are processed according to the actual drawings of customers.

By surface treatment

1. Anodized aluminum
2. Electrophoretic coated aluminum
3. Powder Coated Aluminum
4. Wood grain transfer aluminum
5. Fluorocarbon sprayed aluminum
6. Polished aluminum (divided into mechanical polishing and chemical polishing)

Production Process

1. Melting and casting is the first process of aluminum production. The main processes are: batching, smelting, casting.

2. Extrusion is a means of forming profiles. First design and manufacture a mold according to the section of the profile product, and use an extruder to extrude the heated round cast rod from the mold. The commonly used grade 6063 alloy also uses an air-cooling quenching process and subsequent artificial aging process to complete the heat treatment strengthening during extrusion. Different grades of heat treatable strengthening alloys have different heat treatment systems.

3. Coloring and oxidation: The surface of the extruded aluminum alloy profile is not strong in corrosion resistance. It must be surface treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum material. The main process is: surface pretreatment, anodizing, sealing

4. Titanium plating process, titanium gold plating process for aluminum profiles, including material selection, polishing, chemical degreasing, water rinsing, activation, and vacuum titanium plating process steps.

Characteristics and properties of aluminum profiles after various surface treatment processes

• Frosted fabric aluminum profile: Frosted aluminum profile avoids the disadvantage that bright aluminum alloy profiles will cause light interference in certain environments and conditions in architectural decoration. Its surface is as delicate and soft as brocade, which is very popular in the market.

• Multi-tone surface-treated aluminum profiles: monotonous silver white and brown can no longer meet the architects' good cooperation with exterior wall decorative tiles and exterior wall latex, new stainless steel, champagne, golden, titanium, red series ( Wine red, burgundy, black, purple), etc. and stained glass can make the decorative effect even better. These profiles must be chemically or mechanically polished and then oxidized to achieve good results.

• Electrophoretic painted aluminum profiles: The surface of the electrophoretic painted profiles is soft and can resist the erosion of cement and mortar acid rain. 90% of the aluminum profiles in Japan are electrophoretic painted.

• Powder electrostatic spraying aluminum profiles: powder electrostatic spraying profiles are characterized by excellent corrosion resistance, acid and alkali salt spray resistance is much better than oxidation coloring profiles.

• Plasma Enhanced Electrochemical Surface Ceramicized Aluminum Profile: This type of profile is the most advanced processing technology in the world today. This profile product is of good quality, but the cost is high. It has more than 20 kinds of colors, and its biggest feature is that it can be colored like a printed cloth according to the needs, the surface of the profile is colorful, and the decorative effect is excellent.
