ความแข็งของแผ่นอะลูมิเนียมเป็นกุญแจสำคัญในการหักงอหรือไม่. ความแข็งของแผ่นอลูมิเนียมสูงเกินไปและแตกง่าย. ความแข็งของแผ่นอลูมิเนียมนั้นสัมพันธ์กับเกรดและสถานะของแผ่นอลูมิเนียม.

1. แผ่นอะลูมิเนียมเกรดซีรีส์ที่งอได้: โดยปกติ 1 ชุด, 3 ชุด, และ 5 แผ่นอลูมิเนียมซีรีส์มักใช้สำหรับการดัด.
2. Series of aluminum plates that are not used for bending: เดอะ 6 ซีรีย์และ 7 series have high hardness. โดยทั่วไป, they are delivered in the state of medium-thick aluminum plates. They are not used for bending. If they are bent, they must be annealed to the 0 state before they can be bent.

The relationship between the state of the aluminum plate and the bending

1. The hardness of pure aluminum is not very high, and the commonly used ones are 1060, 1100, 1050, ฯลฯ, which can be bent;
2. 3 series aluminum manganese alloy aluminum plate: 3003, 3005, 3A21, ฯลฯ. can also be bent;
3. 5 series aluminum-magnesium alloy plate, 5052H32 is the most commonly used, it will not crack when bent at 90 องศา.

The relationship between the state of the aluminum plate and the bending

The state of aluminum plate is divided into full hard, กึ่งแข็ง, and soft state (usually the soft state is called O state)

1. Hard state: The bending effect of full hard is basically not very good, such as H18, H19, H38, ฯลฯ. are all hard, 6061, 2024, 7075 ที6, T651 are hardened plates and cannot be bent;
2. Semi-hard: Semi-hard aluminum plates can basically be bent, such as H24;
3. Soft state: 0 state, 5052-0 state, 5083-0 state, ฯลฯ, soft bending is definitely no problem, and the bending zero degree angle is 180 องศา. This state must be used, which is suitable for some special-purpose products. Because it is too soft and low in strength, it has relatively few applications.
