| 详细介绍：
美铝国际上已经注册的铝合金牌号有1000多个，每个牌号又有多种状态，在硬度，强度，耐蚀性，加工性，焊接性，装饰性等方面都存在着明显的差异。选择铝合金的牌号与状态时，以上各方面很难同时满足，也没有必要，应根据产品的性能要求，使用环境，加工过程等因素，设定各种性能的优先次序，方可做到合理选材，在保证性能的前是下合理控制成本。
硬度：很多客户在购买铝时非常关心，硬度首选跟合金化学成份有直接的关系。其次，不同的状态也影响较大，从所能达到的最高硬度来看，7系，2系，4系，6系，5系，3系，1系，依次降低。
强度：强度是产品设计时必须考虑的重要因素，成其是铝合金组件作为组件时，应根据所承受的压力，选择适当的铝合金。纯铝强度最低，而2系及7系热处理型合金度最高，硬度和强度有一定的下相关系。
耐蚀性：耐蚀性包括化学腐蚀，耐应力腐蚀等性能。一般而言，1系纯铝的耐蚀性最佳，5系表现良好，其次是3系和6系，2系及7系较差。耐蚀性选用原则应根据其使用场合而定。高强度合金腐蚀环境下使用，必须使用各种防蚀用复合材料。
加工性：加工性能包插成形性能与切削性能。因为成形性与状态有关，在选择铝合金牌号后，还需考虑各种状态的强度范围，通常强度高的材不易成形。台果要对铝材进行折弯，拉伸，深冲等成形加工，完退火状态材料的成形性最佳，反之，热处理状态材料的成形性最差。铝合金的切削性较差，对于模具，机械零件等需要切削性较佳，反之，低强度者切削性较差，对模具，机械零件等需要切削加工的产品，铝合金的切削性是重要的考虑因素。
焊接性：多数铝合金的焊接性均无问题，尤其是部分5系列的铝合金，是专为焊接考虑而设计的，相对面言，部分2系和7系的铝合金较难焊接。
装饰性能：铝合金应用于装饰或某些特定的场合时，需要对其表面进行阳极氧化，涂装等加工，以获得相应的颜色和表面组织，这时其装饰性应该重点考虑的，一般而言，耐蚀性较好的材料，其阳极处理性能，表面处理性能，涂装性能都非常出色。
其他特性：除上述特性以外，还有导电性，耐磨性，耐热性等。在选材时也可以加以考虑。

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.
