Features of Aluminum Extrusion
With the development of Aluminum Extrusion technology, we have the quality of Aluminum Extrusion requirements are getting higher and higher. Aluminum Extrusion manufacturers of natural Aluminum Extrusion deep processing equipment and technical requirements of the staff are higher, which flatness of the profile is one of the required quality indicators. So what are the characteristics of Aluminum Extrusion?
1, corrosion resistance
The density of Aluminum Extrusion is only 2.7 g / cm3, which is about 1/3 of the density of steel, copper or brass (7.83 g / cm3, 8.93 g / cm3, respectively). In most environmental conditions, including in the air, water (or salt water), petrochemical and many chemical systems, aluminum can show excellent corrosion resistance.
2, conductivity
Aluminum Extrusion is often used because of its excellent conductivity. On the basis of equal weight, the electrical conductivity of aluminum is nearly twice that of copper.
3, thermal conductivity rate
The thermal conductivity of the aluminum alloy is about 50-60% of the copper, which is beneficial for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils and car cylinder heads and radiators.
4, non-ferromagnetic
Aluminum Extrusion is non-ferromagnetic, which is an important feature for the electrical industry and the electronics industry. Aluminum Extrusion is not self-igniting, which is important for applications involving handling or contact with flammable and explosive materials.
5, Machinability
The machinability of Aluminum Extrusion is excellent. Among the various deformable aluminum alloys and cast aluminum alloys, and in the various states that have been produced in these alloys, the machinability of the composites varies considerably, requiring special machine tools or techniques.
6, formability
Specific tensile strength, yield strength, ductility and the corresponding work hardening rate dominate the change in allowable deformation.
7, Aluminum Extrusion with recycling
Aluminum has a very high recovery, the characteristics of recycled aluminum and native aluminum is almost no difference.
General Aluminum Extrusion surface treatment methods are: anodizing, electrophoresis coating and powder coating three, each treatment has its own advantages, occupy a considerable market share. Jiahua aluminum here and we talk about the advantages of Aluminum Extrusion powder coating:
1, the process is relatively simple, mainly due to the production process of the main equipment of the automatic accuracy of the improvement of some of the major technical parameters can be achieved microcomputer control, effectively reduce the difficulty of process operation, while greatly reduce the auxiliary equipment;
2, Aluminum Extrusion yield is high, under normal circumstances, if the measures properly, can maximize the control of nonconforming product production;
3, the energy consumption is significantly reduced, in the ordinary anodizing, electrophoretic coating production process, water, electricity consumption is quite large, especially in the oxidation process. Rectifier output current can reach between 8000 ~ 11000A, the voltage between 15 ~ 17.5V, coupled with the machine's own heat, need to keep using circulating water for cooling, tons of power consumption is often around 1000 degrees, While the reduction of ancillary facilities can also reduce some of the power consumption;
4, the degree of pollution of water, the atmosphere to reduce the alkali, sulfuric acid and other liquid organic solvents are no longer used to reduce water and air pollution, but also effectively improve the Aluminum Extrusion and environmental protection products as a competitive strength of steel profiles, the corresponding To reduce the number of production costs;
5, Aluminum Extrusion workers labor intensity was significantly reduced, due to the use of automated assembly line operations, feeding methods and the use of fixtures has been significantly simplified, improve production efficiency, but also reduce labor intensity;
6, the quality requirements of the surface of the wool material significantly reduced, the powder coating and can completely cover the profile of the extrusion pattern, cover a part of the Aluminum Extrusion surface defects, improve the surface quality of Aluminum Extrusion products;
7, Aluminum Extrusion coating of some physical indicators than other surface treatment film has improved significantly, such as hardness, wear resistance, can effectively extend the service life of Aluminum Extrusion.
