美鋁國際上已經注冊的鋁合金牌號有1000多個,每個牌號又有多種狀態,在硬度,強度,耐蝕性,加工性,焊接性,裝飾性等方面都存在著明顯的差異。選擇鋁合金的牌號與狀態時,以上各方面很難同時滿足,也沒有必要,應根據產品的性能要求,使用環境,加工過程等因素,設定各種性能的優先次序,方可做到合理選材,在保證性能的前是下合理控制成本。
硬度:很多客戶在購買鋁時非常關心,硬度首選跟合金化學成份有直接的關系。其次,不同的狀態也影響較大,從所能達到的最高硬度來看,7系,2系,4系,6系,5系,3系,1系,依次降低。
強度:強度是產品設計時必須考慮的重要因素,成其是鋁合金組件作為組件時,應根據所承受的壓力,選擇適當的鋁合金。純鋁強度最低,而2系及7系熱處理型合金度最高,硬度和強度有一定的下相關系。
耐蝕性:耐蝕性包括化學腐蝕,耐應力腐蝕等性能。一般而言,1系純鋁的耐蝕性最佳,5系表現良好,其次是3系和6系,2系及7系較差。耐蝕性選用原則應根據其使用場合而定。高強度合金腐蝕環境下使用,必須使用各種防蝕用復合材料。
加工性:加工性能包插成形性能與切削性能。因為成形性與狀態有關,在選擇鋁合金牌號后,還需考慮各種狀態的強度范圍,通常強度高的材不易成形。臺果要對鋁材進行折彎,拉伸,深沖等成形加工,完退火狀態材料的成形性最佳,反之,熱處理狀態材料的成形性最差。鋁合金的切削性較差,對于模具,機械零件等需要切削性較佳,反之,低強度者切削性較差,對模具,機械零件等需要切削加工的產品,鋁合金的切削性是重要的考慮因素。
焊接性:多數鋁合金的焊接性均無問題,尤其是部分5系列的鋁合金,是專為焊接考慮而設計的,相對面言,部分2系和7系的鋁合金較難焊接。
裝飾性能:鋁合金應用于裝飾或某些特定的場合時,需要對其表面進行陽極氧化,涂裝等加工,以獲得相應的顏色和表面組織,這時其裝飾性應該重點考慮的,一般而言,耐蝕性較好的材料,其陽極處理性能,表面處理性能,涂裝性能都非常出色。
其他特性:除上述特性以外,還有導電性,耐磨性,耐熱性等。在選材時也可以加以考慮。

Aluminum alloy grade Alcoa international registered more than 1000, each grade alsohas a variety of state, the hardness, strength, corrosion resistance, workability,weldability, decoration and other aspects of the existence of significant differences.Select the grade and status of aluminum alloy, the above aspects are very difficult to satisfy, it is not necessary, according to the requirements of the performance of the products, the use of the environment, process and other factors, set all kinds ofperformance priorities, party can do a reasonable selection, to guarantee the performance of the former is lower at reasonable cost control.
Hardness: many customers are very concerned about in the purchase of aluminum,chemical composition of alloy with hardness of choice has a direct relationship.Secondly, different state is also a greater impact, from the highest hardness can reach, 7 series, 2 series, 4 series, 6 series, 5 series, 3 series, 1 series, in order to reduce the.
Intensity: intensity is an important factor to be considered in design of products, its arealuminum alloy components as component, should be based on the pressure, the appropriate choice of aluminum alloy. Minimum strength aluminum, while the 2 line and 7 line heat treatment of alloy phase relationship with highest degree, under certain degree of hardness and strength.
Corrosion resistance: corrosion resistance including chemical corrosion, stress corrosion resistant properties. In general, 1 lines of pure aluminum the best corrosion resistance performance is good, 5 series, followed by the 3 series and 6 series, 2 series and 7 series of poor. The corrosion resistance of the selection principle should be based on the use of occasions and. The use of the environment corrosion alloyhigh strength, must use a variety of composite material for corrosion protection.
Processing: performance and cutting performance of inserting and forming processingperformance package. Because the formability and state, in the choice of aluminium alloys, also need to consider the strength range of various state, usually of high strength material not easily forming. If must carry on the aluminum tensile, bending,deep drawing forming process after annealing state material formability is best, on the other hand, heat treatment state of materials forming the worst. The cutting of the poor, aluminum alloy for die, machinery parts and other need cutting better, on the contrary, the low strength of the cutting of the poor, to die, machinery parts and otherneeds of machining products, cutting of aluminum alloy are important factors to consider.
Welding: most of the weldability of aluminum alloys are no problem, especially foraluminum alloy 5 series parts, is designed for welding to consider and design, the relative surface words, aluminum alloy parts of the 2 and 7 series is difficult to weld.
Decorative performance: aluminum alloy used in decorative or some special occasions, in need of anodic oxidation on the surface coating processing, in order to obtain the corresponding color and surface tissue, then the decoration should be a key consideration, in general, good corrosion resistance material, its anodeprocessing properties, surface treatment coating performance. Performance are very good.
Other features: in addition to the above characteristics outside, and electrical conductivity, wear resistance, heat resistance, etc.. In the material can also be taken into account.
