6 mambo ya kuzingatia kwa uteuzi wa aloi ya sahani ya alumini

1, Ugumu: many customers are very concerned when buying aluminum sheet plate alloy, ugumu unapendekezwa kuwa na uhusiano wa moja kwa moja na muundo wa kemikali wa aloi. Pili, majimbo tofauti pia yana athari kubwa, kutoka kwa ugumu wa hali ya juu unaoweza kupatikana, 7 mfululizo, 2 mfululizo, 4 mfululizo, 6 mfululizo, 5 mfululizo, 3 mfululizo, 1 mfululizo, in descending order.

2, Nguvu: strength is an important factor that must be considered when designing products, by its aluminum plate as a component, should be based on the pressure to be borne, choose the appropriate alloy. Pure aluminum strength is the lowest, na 2 mfululizo na 7 series heat treatment type aluminum plate hardness is the highest, hardness and strength have a certain under phase relationship.

3, Upinzani wa kutu: corrosion resistance including chemical corrosion, stress corrosion resistance and other properties. Kwa ujumla, 1 series of pure aluminum corrosion resistance is the best, 5 series of good performance, followed by 3 mfululizo na 6 mfululizo, 2 mfululizo na 7 series is poor. Corrosion resistance selection principle should be based on its use of the occasion. High-strength alloys used in corrosive environments, must use a variety of corrosion-resistant composite materials.

4, Inachakata: processing performance package insert forming performance and cutting performance. Because the formability and state, in the choice of aluminum plate grade, but also need to consider the strength range of various states, usually high strength material is not easy to form. If you want to bend, stretch and deep punch the aluminum, the forming property of the material in the annealed state is the best, and vice versa, the forming property of the material in the heat treatment state is the worst. The machinability of aluminum plate is poor, for the mold, mechanical parts and other products that need to be machined better, and vice versa, the machinability of low strength is poor, for the mold, mechanical parts and other products that need to be machined, the machinability of aluminum plate is an important consideration.

5, Weldability: most of the aluminum plate weldability are no problem, especially part of the 5 series of aluminum plate, is designed for welding considerations, relative to the face, part of the 2 mfululizo na 7 series of aluminum plate more difficult to weld.

6, Utendaji wa mapambo: aluminum used in decoration or some specific occasions, the need for its surface anodizing, painting and other processing, in order to obtain the corresponding color and surface organization, when its decorative should focus on consideration, kwa ujumla, corrosion resistance of better materials, its anodizing performance, surface treatment performance, painting performance are very good.
