Product Description:

Aluminium is a relatively soft, durable, lightweight, ductileand malleablemetalwith appearance ranging from silvery to dull gray, depending on the surfaceroughness. It is nonmagnetic and does not easily ignite. A fresh film ofaluminium serves as a good reflector (approximately 92%) of visible lightand an excellent reflector (as much as 98%) of medium and far infraredradiation. The yield strength of pure aluminium is 7–11 MPa,while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the densityand stiffness of steel. It is easily machined,cast, drawn and extruded.

Q:What are the specific features of industrial aluminum profiles?
Industrial aluminum profile features, we use four words to sum up: a wide range of applications, construction convenience, handsome in appearance, practical, scalable. Remember to adopt yo! Thanks
Q:Aluminum profiles and plastic doors and windows which good, what market?
Aluminum profiles and plastic doors and windows are not absolute, which is good or bad, each has its own advantages.1, Aluminum Alloy regular manufacturers are standard models of materials, thickness of 1.2 mm or more, and surface spraying or electrophoresis are very bright, the thickness of the coating is thick, make the effect and its performance are good. The insulation and heat insulation effect of the doors and windows made of plastic steel profiles and plastics are very good. Advantages: heat insulation, heat preservation, sound insulation, aging resistance, tightness2, plastic doors and windows using multi-layer sealing design, and type only smooth surface, not easy to adhesion dust, dirt, dustproof effect is excellent. Elegant and beautiful, plastic steel can be matched into a variety of colors.
Q:How to deal with the mechanical surface of aluminum profile?
Mechanical texture removal also has mechanical methods, chemical methods can not remove deeper texture, if sand blasting effect is acceptable, you try sand blasting or shot peening
Q:Does aluminum alloy profile conduct electricity?
Aluminum conducts well, and aluminium alloys must also be electrically conductive. But aluminum alloys contain impurities such as silicon and magnesium
Q:How to design the extrusion die for aluminum extrusion? Ten
With the stamping die almost the same, hard to learn ah!
Q:Are there any differences between aluminum alloy and aluminum alloy?
Aluminum alloy refers to the material, aluminum alloy refers to the productIt's like the difference between gold and gold
Q:Can Linqu aluminum profile factory have 100 home?
Some of the largest Huajian aluminum industry in Linqu there is no doubt that there are a lot of good after scale manufacturers, such as Albert Wei Sheng Jian Zhonghao new east to east of Yangtze River following so little that it is not representative of the product but a superb collection of beautiful things, not in Linqu, most of the manufacturers is YISHION aluminum ingots as raw material, processing technology is advanced basically, can ensure the quality of products. Louzhu should mention the one hundred, because there is only a scale can reach 53 (news reports), the number of small scale is much larger than this number, so the one hundred aluminum manufacturers should be more than enough, thank you for adopting!
Q:What are the major factors determining the quality of aluminum profiles?
Then, how to distinguish the aluminum profile is good or bad? Let's get to know those aluminum profiles that are not qualified.First, extrusion defects.Aluminum extrusion process for machine equipment is perfect, process technology is mature and whether the operation staff misconduct and other reasons, will lead to aluminum flakes, such as inclusion, delamination, chromatic aberration, distortion and other defects, affecting the quality of aluminum profiles.Second, the film thickness is thin.Industrial aluminum oxide film thickness standard should be not less than 10um (m). If the thickness is not enough, the surface of the aluminum profile is easy to rust and corrode and shorten the service life. In order to save the cost, the thickness of the oxide film is only 2 to 4um, and some even have no oxide film. It is estimated that each reduction of 1um film thickness can reduce power consumption by more than 150 yuan per ton. Thus, they can earn a lot of profits, that is why some customers say that certain companies quoted lower prices than us.Third, the chemical composition is not qualified.Some manufacturers in order to retain customers, at the incorporation of a large number of miscellaneous scrap aluminum, aluminum can greatly reduce the cost, but will lead to industrial aluminum unqualified chemical compositions, seriously endanger the life of aluminum.Fourth, reduce the wall thickness of profiles.Some manufacturers will make aluminum profile wall thickness is insufficient, originally 1.5MM thick aluminum, they in order to save costs, only 1.2MM, in this way, an aluminum prices must be cheaper. But customers do not know, but also that a good supplier found, in fact, cheated, but also to help him count the money.
Q:What are the factors involved in the selection of industrial aluminum profiles?
Hardness: many customers are very concerned about the purchase of aluminum, and the preferred hardness is directly related to the chemical composition of the alloy. Secondly, the different states also have great influence. From the highest hardness, 7 lines, 2 lines, 4 lines, 6 lines, 5 lines, 3 lines, 1 lines are reduced in turn.Strength: strength is an important factor that must be taken into consideration when designing a product. As an aluminum alloy component, the appropriate alloy shall be selected according to the pressure to be taken. The strength of pure aluminum is the lowest, while the 2 and 7 series heat treatment alloys have the highest degree, and the hardness and strength have a certain lower phase relationship.
Q:Aluminum profiles and aluminum profiles (material)
Aluminum material refers to the blank material, which is used directly without artificial aging
