第五部分铝的表示方法

Part 5: Representation Methods of Aluminum

铝材的标记：

产品标记按产品的名称，牌号，状态，规格及标准编号的顺序表示：

例如：1060合金，状态H24，厚度1.0毫米，宽度1000毫米，长度2000毫米的铝板

标记为：铝板：1060H24：1.0*1000*2000：GB/T3880-2012。

例如：3003合金，状态0态，厚度1.0毫米，宽度1000毫米的铝卷

标记：铝卷：3003-0：1.0*1000 或1.0*1000*L    GB/T3880-2012.

Marking of Aluminum Materials

Product markings are expressed in the order of the product’s name, alloy grade, temper, specifications, and standard number:

Example 1: Aluminum plate of Alloy 1060, Temper H24, thickness 1.0mm, width 1000mm, length 2000mmMarking: Aluminum Plate: 1060H24: 1.0×1000×2000: GB/T 3880-2012

Example 2: Aluminum coil of Alloy 3003, Temper O, thickness 1.0mm, width 1000mmMarking: Aluminum Coil: 3003-O: 1.0×1000 or 1.0×1000×L; GB/T 3880-2012

铝卷的内径国标有：

75、150、200、300、405、505、610、650、750.

我们一般常用是505，其次为300、610等。

The national standard (GB) specifies the following inner diameters for aluminum coils:75, 150, 200, 300, 405, 505, 610, 650, 750 (unit: mm, typically implied in aluminum processing contexts).

Among these, 505 is the most commonly used in our practice, followed by 300, 610, and others.

常用铝合金化学性能 Chemical Properties of Commonly Used Aluminum Alloys：

（1）抗拉强度：样本单位面积所能承受的最大拉力。拉力/面积  Pa=牛/平方毫米 兆Pa=Pa*106

Tensile Strength: The maximum tensile force that a sample can withstand per unit area.Calculation formula: Tensile force / AreaUnit conversion: Pa = N/mm² (Newton per square millimeter); MPa (Megapascal) = Pa × 10⁶

（2）硬度：样本单位面积上所能承受的最大压力。压力/表面积（所压圆面的）。通用布氐硬度（HB）

Hardness: The maximum pressure that a sample can withstand per unit area.Calculation basis: Pressure / Surface area (referring to the pressed circular area).Commonly used standard: Brinell Hardness (HB).

（3） 延伸率：试样单位拉断后，测量的最大延伸长度 

Elongation: After a test specimen is pulled to fracture, it refers to the maximum extended length measured.

基本状态分为5种

There are 5 types of basic tempers.

经常用到的状态表示方法：

退火：把金属加热到一定的温度自然冷却以达到需求的强度。（使金属变软的工艺）

淬火：把金属加热到一定的温度突然冷却以达到需求的硬度。（使金属增加硬度的工艺）

Commonly used temper designations:

Annealing: A process that softens the metal by heating it to a certain temperature and then allowing it to cool naturally to achieve the required strength.

Quenching: A process that increases the hardness of the metal by heating it to a certain temperature and then cooling it suddenly to achieve the required hardness.

基础代号 Basic Designations：

0：完全退火状态。达到最低强度。

H：加工硬化，提高强度。

H后面添加两位阿拉伯数字（称作HXX状态），或三位阿拉伯数字（称作HXXX状态）表示H
的细分状态。

H后面的第1位数字表示获得该状态的基本处理程序 

0: Fully annealed temper. Achieves the minimum strength.

H: Work-hardened temper. Enhances strength.When two Arabic numerals are added after H (referred to as HXX temper) or three Arabic numerals are added after H (referred to as HXXX temper), they represent the subdivided tempers of H.The first numeral after H indicates the basic processing procedure used to obtain this temper.

铝的表示方法-5

H1：加工硬化处理状态。

适用于未经附加热处理，只经加工硬化即获得所需强度的状态。

H1: Work-hardened temper. It is applicable to the temper where the required strength is achieved only through work hardening, without additional heat treatment.

H2：加工硬化及不完全退火的状态。

适用于加工硬化程度超过成品规定要求后，经不完全退火，使强度降低到规定指标的产品。对于室温下自然时效软化的合金， H2与对应的H3具有相同的最小极限抗拉强度值；对于其它合金，H2与对应的H1具有相同的最小极限抗拉强度值，但延伸率比H1稍高。 

H2: Temper of work hardening and incomplete annealing.It is applicable to products where the degree of work hardening exceeds the specified requirements for the finished product, and then the strength is reduced to the specified index through incomplete annealing. For alloys that soften due to natural aging at room temperature, H2 has the same minimum ultimate tensile strength value as the corresponding H3; for other alloys, H2 has the same minimum ultimate tensile strength value as the corresponding H1, but its elongation is slightly higher than that of H1.

H3：加工硬化及稳定化处理的状态。

适用于加工硬化后经热处理或由于加工过程中受热作用致使其力学性能达到稳定的产品。H3状态仅适用于在室温下逐渐时效软化（除非经稳定化处理）的合金。

H3: Temper of work hardening and stabilization treatment.It is applicable to products where the mechanical properties are stabilized through heat treatment after work hardening, or due to heat exposure during the processing. The H3 temper is only suitable for alloys that gradually soften by aging at room temperature (unless stabilized by treatment).

H4：加工硬化及涂漆处理的状态。适用于加工硬化后，经涂漆处理导致了不完全退火的产品。

H4: Temper of work hardening and painting treatment.It is applicable to products that undergo painting treatment after work hardening, which results in incomplete annealing.
铝的表示方法-6

例如 e.g.：

  H18：第一位1是加工硬化

  H24：第一位2加工不完全退火

 H32：第一位3是加工后低温退火。加工硬化及稳定化处理的状态。

后面数量1-8是指强度的变化，1低-2-3-8高

 H后面的第2位数字表示产品的加工硬化程度。数字8表示硬状态。对于O（退火）和HX8状态之间的状态，应在HX代号后分别添加从1到7的数字来表示，在HX后添加数字9表示比HX8加工硬化程度更大的超硬状态，各种HXX细分状态代号及对应的加工硬化程度

H18: The first digit "1" indicates work hardening.

H24: The first digit "2" indicates work hardening followed by incomplete annealing.

H32: The first digit "3" indicates work hardening followed by low-temperature annealing; this refers to the temper of work hardening and stabilization treatment.

The subsequent digit (ranging from 1 to 8) represents the degree of strength: 1 for low strength, and the strength increases progressively from 2, 3 up to 8 (the highest strength).

The second digit after "H" denotes the degree of work hardening of the product. The digit "8" indicates the full-hard temper. For tempers between O (annealed) and HX8, digits from 1 to 7 shall be added respectively after the HX designation to represent them. Adding the digit "9" after HX indicates the extra-full-hard temper, which has a higher degree of work hardening than HX8. Below are the designations of various HXX subdivided tempers and their corresponding degrees of work hardening.

H112: Suitable for the free-machining temper of hot-rolled plates and products formed by hot working.

H116: Applicable to products made of 5XXX series alloys with a magnesium content of ≥ 4.0%. These products have specified requirements for mechanical properties and exfoliation corrosion resistance.

T：热处理：经过加工硬化达到稳定状态。

T4：淬火后自然时效

T6：淬火后人工时效

T: Heat Treatment: A temper where a stable state is achieved through work hardening.

T4: Naturally aged after quenching

T6: Artificially aged after quenching
　 　 在字母T后面添加一位或多位阿拉伯数字表示T的细分状态。 　 
　 　 在T后面添加0~10的阿拉伯数字，表示细分状态（称作TX状态）。T后面的数字表示对产品的处理程序。

One or more Arabic numerals are added after the letter "T" to represent the subdivided tempers of "T".

Arabic numerals from 0 to 10 are added after "T" to denote subdivided tempers (referred to as TX tempers). The numeral(s) after "T" indicate the processing procedure(s) applied to the product.

TX51：消除内应力TX51: Stress Relieved (to eliminate internal stress)

T状态及TXXX状态（消除应力状态外）
在TX状态代号后面再添加一位阿拉伯数字（称作TXX状态），或添加两位阿拉伯数字（称作TXXX状态），表示经过了明显改变产品特性（如力学性能、抗腐蚀性能等）的特定工艺处理的状态。 

消除应力状态：在上述TX或TXX或TXXX状态代号后面添加“51”、或“510”、或“511”或“52”或“54”表示经历了消除应力处理的产品状态代号。

T Temper and TXXX Temper (Excluding Stress-Relieved Tempers)After the TX temper designation, an additional Arabic numeral is added (referred to as the TXX temper) or two additional Arabic numerals are added (referred to as the TXXX temper). These designations represent tempers that have undergone specific processing treatments which significantly alter the product’s characteristics (such as mechanical properties, corrosion resistance, etc.).

Stress-Relieved Tempers: After the aforementioned TX, TXX, or TXXX temper designations, adding "51", "510", "511", "52", or "54" indicates the product temper designation that has undergone stress-relief treatment.

W（固熔热处理状态）的消除应力状态 ：如T的消除应力状态代号表示方法，可在W状态代号后面添加相同的数字（51、52、54），以表示不稳定的固溶热处理及消除应力状态。

Stress-relieved temper of W (solution heat-treated temper): Similar to the designation method for stress-relieved tempers of T, the same numerals (51, 52, 54) can be added after the W temper designation to indicate the unstable solution heat-treated and stress-relieved temper.

铝板牌号各字符表示的意思Meaning of Each Character in Aluminum Plate Grade Designations：

例如：1060：表示：第一位：1表示：合金系列

                  第二位：0表示：改形情况：一次改动A。二次改动：B。无改动：0                    第三位：60表示铝含量是99.6%

For example: 1060: It indicates:

The first digit "1" represents the alloy series.

The second digit "0" indicates the modification status: "A" for the first modification, "B" for the second modification, and "0" for no modification.

The third and fourth digits "60" indicate that the aluminum content is 99.6%.

1000系列铝板根据最后两位阿拉伯数字来确定这个系列的最低含铝量，比如1050系列最后两位阿拉伯数字为50，根据国际牌号命名原则，含铝量必须达到99.5%以上方为合格产品。我国的铝合金技术标准(gB/T3880-2006)中也明确规定1050含铝量达到99.5%.同样的道理1060系列铝板的含铝量必须达到99.6%以上。

 5052：表示：第一位：5表示5系合金

             第二位：0表示改形情况

             第三位：52是同系中的编号

For aluminum plates of the 1000 series, the minimum aluminum content of the series is determined by the last two Arabic numerals. For example, the last two Arabic numerals of the 1050 series are "50". In accordance with the international grade naming principles, only products with an aluminum content of 99.5% or higher are considered qualified. China's aluminum alloy technical standard (GB/T 3880-2006) also clearly specifies that the aluminum content of 1050 series shall reach 99.5%. By the same logic, the aluminum content of aluminum plates in the 1060 series must be 99.6% or higher.

5052 (designation explanation):

The first digit "5" indicates it belongs to the 5XXX alloy series.

The second digit "0" indicates the modification status.

The third and fourth digits "52" represent the serial number within the same alloy series.
