Basic Knowledge of Industrial Aluminum-Aluminum Profiles SUPPLIER

Basic Knowledge of Industrial Aluminum I. Classification: Stretching data is divided into non-thermal treatment alloys and heat treatment alloys 1. Non-thermal treatment alloy: pure aluminum-1000 series, aluminum manganese series-3000 series, aluminum silicon series-4000 series, aluminum and magnesium series- 5000 series.

2. Hot treatment alloy: aluminum, copper and magnesium alloy 2000 series, aluminum magnesium silicon alloy 6000 series, aluminum zinc and magnesium alloy 7000 series.

two. Alloy number: At present, the number of "Aluminum Association" is commonly used in China.

2. Second -digit number: represents a deterioration alloy with significantly increased alloy content or impurities in the original alloy. 0: Original alloy 1: The first modification of the primitive alloy 2: The original alloy has been modified for the second time 3. The third, third and fourth digits: Pure aluminum: refers to the original alloy alloy: the code of a single alloy "-" : The hn or Tn behind indicates the hardness symbol of the processing hardening or the heat treatment status-HN: indicates the hardness symbol of the non-thermal treatment alloy-TN: indicates the hardness symbol of the thermal treatment alloy

(2) Thermal treatment of aluminum and industrial aluminum materials 1. Hardness symbol: If the amount of alloy elements is not enough to fully meet the requirements, the timeliness processing and soft burning need to be performed to obtain the required strength and function. The process of these treatment is called quality adjustment, and the result of the quality adjustment is hardness. The hardness of the hardness symbol definition of the manufacturing conditions does not have the finished products made by specific hardness manufacturing, such as squeezing, hot rolling, casting, etc. H112 does not deliberately control the degree of processing hardening, but the mechanical performance must be guaranteed. o The soft combustion system completely focuses on crystals and the softest conditions.

If it is a thermal treatment alloy, it must be slowly cooled from the soft burning temperature to completely avoid water quenching. H processing hardened hardness H1N: Cold processing and processing hardening H2N: After processing hardening, apply moderate soft burning H3N: After processing hardening The level n = 2 means 1/4 hard n = 4 indicates 1/2 hard n = 6 indicates 3/4 hard n = 8 indicates hard n = 9 indicates super hard t -: high temperature processing is natural after cooling Ageing. The squeezing molding is quickly cooled after heat processing, and then the constant temperature is more than ten times. You can also correct it without affecting the strength. This type of quality is suitable for 6063 and other heat processing alloys after cooling after cooling. T3: The goal of cold processing after solid solution is to improve intensity, flatness and size accuracy. Industrial aluminum classification according to the application field. Industrial aluminum profiles refer to all aluminum profiles other than building doors and windows, curtain walls, indoor and outdoor decoration and building structures. T36: T3 cold processing 6%. Industrial aluminum classification according to the application field. Industrial aluminum profiles refer to all aluminum profiles other than building doors and windows, curtain walls, indoor and outdoor decoration and building structures. T361: Cold processing is greater than T3. T4: Natural aging treatment after solid solution treatment. T5: After heat processing, quickly cool down, and then perform labor time processing. The goal of artificial time processing is to improve the mechanical properties and size stability of data. It is suitable for 6063 and other alloys with water quenching after cooling processing. T6: Artificial time processing after dissolving. This is the representative thermal treatment of thermal treatment alloy. You can get excellent strength without cold processing. The hot -melt squeeze of industrial profiles can obtain aluminum with different section shapes.

However, due to the different proportion of alloys, the mechanical properties and application areas of industrial aluminum profiles are also different.

If the high intensity cannot be guaranteed, the correction after cold processing or solid solution treatment for improved size accuracy can also be regarded as T6 chain. T61: After solid solution treatment, warm water quenching and artificial timeliness are performed. The purpose of warm water quenching is to avoid deformation. T7: After dissolving treatment, stable treatment is performed (similar, the temperature or time of labor time processing is higher than or longer than T6 treatment). The purpose is to improve crack resistance and avoid deformation during water quenching. T7352: After dissolving treatment, remove the residual stress, and then perform timeliness (similarly, the temperature or time of labor time processing is higher than or longer than T6 treatment). The goal is to improve anti -hard cracking. After solid solution treatment, 1 5%permanent deformation is applied to eliminate residual stress. T8: Cold processing after solid solution, manual timeliness. The section contraction rates during cold processing are 3%and 6%, respectively, T83 and T86, respectively. T9: Artificial time processing after solid solution treatment, and finally cold processing, the purpose is to increase the intensity.

Second, soft burning processing: 2.1 target: stretching data includes rolling data, squeezing data and casting data.

Generally, its manufacturing process is as follows: During the heat processing or cold processing process of casting thermal processing heat processing, the data will generate processing hardening. Machining hardening will increase strength or cause processing hardening, increase strength or reduce processability. In order to eliminate these processing hardening, the heat treatment of before, during or after cold processing is called soft burning processing. The goal is to make the data exist at the necessary utilization level.

2.2 Category: Because the premise of soft burning is different: 2.2.1 Local soft burning: only eliminate part of the processing hardening, and the treatment temperature is lower than the crystallization temperature. The actual temperature depends on the strength. The higher the strength, the lower the treatment temperature.
