In the process of processing, the aluminum sheet needs to be annealed to achieve different degrees of softness and hardness. With the length of the annealing time, the stretching and elongation of the aluminum sheet will also change continuously. That is to say, the longer the annealing time, the more suitable this aluminum alloy is for the drawing process. The O-state annealing process is a more suitable annealing state.

What kind of aluminum sheet can be stretched?

1.1 series 1060 stretched aluminum sheet: the representative product of 1 series aluminum sheet should be 1060 aluminum sheet, and the annealing state suitable for stretching of 1060 alloy aluminum sheet is H22, H24, and O state. If the stretching is relatively deep, it is suitable to use the O-state aluminum sheet. If it is a general depth, that is, the stretching is not high and the aluminum sheet needs to be maintained with the recommended hardness, then it is recommended to use the H22 and H24 states.

2.3 series 3003 stretched aluminum sheet: Conventionally, if 3003 aluminum sheet is used as the raw material for stretch stamping, it is more suitable for those that are not high in stamping and need to maintain the hardness to a large extent. We generally recommend the use of 3003 stretched aluminum sheet. Do processing. Because the 3-series products generally contain high manganese content, it is generally considered to choose O too annealed to make up for the hardness of the 3-series aluminum sheet.

3.5 series 5052 stretched aluminum sheet: 5052 aluminum sheet is a more commonly used base material for aluminum sheet. The corresponding oxidation process and stamping process are the raw materials for the stretched aluminum sheet process we are talking about now. Because 5052 aluminum sheet has excellent weldability and can be processed by oxidation treatment, 5052 stretched aluminum sheet is generally recommended for use with secondary processing and can be considered as the first material.

4.6 series 6063 stretched aluminum sheet: 6 series alloy aluminum sheet is known as the originator of door and window materials, because 6063 aluminum sheet has good toughness in the field of door and window extrusion, and can well ensure that doors and windows have a high degree of wind pressure resistance, Corrosion resistance and decoration, etc. Therefore, this model of 6063 stretched aluminum sheet is also used in this field, such as fan casings, equipment covers, freezer fan casings and other fields.
