Aluminum profile features:

1, corrosion resistance:

Aluminum profiles have a density of only 2.7g/cm3, about one-third that of steel, copper, or brass (7.83g/ cm3 and 8.93g/ cm3, respectively). Aluminum exhibits excellent corrosion resistance in most environmental conditions, including air, water (or brine), petrochemical, and many chemical systems.

2. Electrical conductivity:

Aluminum profiles are often chosen because of their excellent electrical conductivity. The electrical conductivity of aluminum is nearly half that of copper, weight equal.

3, Thermal conductivity rate:

The thermal conductivity of aluminium alloys is about 50-60% of that of copper, which is good for heat exchangers, evaporators, heating appliances, cooking utensils, as well as cylinder heads and radiators for cars.

4, Non-ferromagnetic:

Aluminum profiles are non-ferromagnetic, an important characteristic for the electrical and electronic industries. Aluminum profiles are non-flammable, which is important for applications involving handling or contact with flammable and explosive materials.

5, Processability:

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

6, Formability:

Specific tensile strength, yield strength, ductility, and corresponding rate of work hardening govern the variation of allowable deformation.

7, Recycling:

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

Aluminum profile classification:

One. By use:

1. Architectural aluminum profiles (divided into doors, Windows and curtain walls).

2. Aluminum profiles for radiator.

3. General industrial aluminum profile: mainly used for industrial production and manufacturing, such as automatic machinery and equipment, the skeleton of the seal cover and the companies according to their own mechanical equipment requirements customized mold, such as assembly line conveyor belt, elevator, dispensing machine, testing equipment, shelves and so on, electronic machinery industry and clean room with the majority.

4. Aluminum alloy profiles for railway vehicle structure: mainly used in the manufacture of railway vehicle body.

5, Mounting aluminum profiles, made into aluminum frame, mounting various exhibitions, decorative paintings.

Two, according to the composition of alloy:

Can be divided into 1024, 2011, 6063, 6061, 6082, 7075 alloy aluminum, among which 6 series is the most common. The difference between different grades is that the ratio of various metal components is not the same, in addition to the commonly used doors and Windows aluminum such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other architectural aluminum, industrial aluminum does not have a clear model distinction, most of the production plants are processed in accordance with the actual drawings of customers.

Three, according to the surface treatment:

1. Anodized aluminum

2. Electrophoretic coating of aluminum

3. Powder sprayed aluminum

4. Wood grain transfer aluminum

5. Fluorocarbon sprayed aluminum

6. Polishing aluminum (divided into mechanical polishing and chemical polishing two kinds, among which the chemical polishing cost is the highest, the price is also the most expensive)

Characteristics and properties of aluminum profiles after surface treatment:

Frosted material aluminum: aluminum frosted surface to avoid the light of aluminium alloy profiles in architectural decoration exists in certain environment, conditions will form the interference of light, it's like brocade and soft surface, is very popular with the market, but the existing grinding material must overcome sand uneven surface, and can see the shortage of the die lines.

Tonal and surface treatment of aluminum, the monotony of silvery white and tan already cannot satisfy architects and exterior wall decoration tile, exterior wall latex is very good, a new type of stainless steel color, champagne color, gold, titanium gold, red series (wine red, purplish red, black, purple) combined with such as colored glass can make adornment effect is the icing on the cake. These profiles must be chemically or mechanically polished and then oxidized to achieve the best results.

Electrophoretic painted aluminum profiles: Electrophoretic painted aluminum profiles have a soft surface gloss and can resist acid rain of cement and mortar. 90% of aluminum profiles in Japan are electrophoretic painted.

Powder electrostatic spraying aluminum profiles: powder electrostatic spraying aluminum profiles are characterized by excellent corrosion resistance, acid, alkali salt spray resistance is much better than oxidized colored profiles.

Plasma-reinforced electrochemical surface ceramic aluminum profiles: these profiles are the most advanced processing technology in the world. This profile product has good quality but high cost. It has 20 kinds of tonal, its biggest characteristic is to be able to cover color like calico cloth according to need, colour profusion of profile surface, adornment effect is excellent.
