1, pure aluminum: pure aluminum (aluminum 3003) series have a common code 1050,1060,1100. In all aluminum series of pure aluminum series is the largest aluminum content of a series. You can reach more than 99.00% purity. Because they do not contain other technical elements, so the production process is relatively simple, relatively inexpensive specialized in producing aluminum extrusion manufacturer, is currently the most commonly used conventional industry a series. Currently on the market most of circulation for 1050 and 1060 series. 2, aluminum alloy: 2 ××× series aluminum alloys: representative 2A16 (LY16), 2A06 (LY6). 2 ××× series aluminum is characterized by high hardness, which was originally the highest concentrations of copper, probably in about 3-5%. 2 ××× series aluminum is aviation aluminum extrusion aluminum, not often present in conventional industrial. The quality of teaching you to identify the problem aluminum 1. The samples were boiled boiled observed 2 hours after cooling observed, there should be no open glue between the aluminum and plastic, according to the method described above aluminum extrusion factory in Shandong, the film should be no glue fall and brittle hair. Brittle fracture is observed under an aluminum veneer cutting force bent aluminum brittle fracture should be obvious. 2. compare prices because the price is the main raw material for aluminum extrusion aluminum Jinan several manufacturers, plus depreciation of equipment, labor and administrative expenses and profits of production, the price is a certain bottom line. Currently aluminum production has almost dropped to the lowest profit significantly low prices must be the most significant feature of fake and shoddy products.
