A thin aluminum sheet metal is a wide and thin sheet extending from an aluminum plate with a thickness of 0.2-6.0 mm. The aluminum grade of aluminum sheet metal rang from 1000 series to 8000 series, and the common used alloys are 1060, 1100, 3003, 3105, 5052, 5083, 5086, 6061 and 7075. To buy thin aluminum sheet, we have suggest for you to consider about the performance.
Hardness: Many customers are very concerned when buying thin aluminum sheet metal, and the hardness is directly related to the chemical composition of the aluminium alloy. Secondly, different tempers also have a greater impact. From the perspective of the higher hardness that can be achieved, the 7000 series, the 2000 series, the 4000 series, the 6000 series, the 5000 series, the 3000 series, and the 1000 series decrease in order.
Strength: Strength is an important factor that must be considered during product design. When it is made of aluminum sheet alloy as components, the appropriate aluminium alloy should be selected according to the pressure it bears. The strength of pure aluminum is low, and the degree of heat-treated aluminium alloys of the 2000 series and 7000 series is higher, and the hardness and strength have a certain downward relationship.
Corrosion resistance: Corrosion resistance includes chemical corrosion and stress corrosion resistance. Generally speaking, the corrosion resistance of pure aluminum of the 1000 series is better, the 5000 series performs well, followed by the 3000 series and 6000 series, and the 2000 series and 7000 series are inferior. The selection principle of corrosion resistance should be determined according to its use occasion. For high-strength alloys to be used in a corrosive environment, various anti-corrosion composite materials must be used.
Decoration performance: When thin aluminum sheet metal is used for decoration or some specific occasions, its surface needs to be processed by anodic oxidation and painting to obtain the corresponding color and surface structure. At this time, its decoration should be considered. Generally speaking , The material with better corrosion resistance has excellent anodizing performance, surface treatment performance and coating performance.
