어떤 종류의 알루미늄 판을 구부릴 수 있나요?

기계 구조 설계 실무자는 종종 알루미늄 합금 재료를 사용합니다., 알루미늄 합금 소재는 세분화되어 있으며 다양한 등급이 있습니다.. 알루미늄 합금 소재를 선택하는 주된 이유는 강도와 밀도의 조합입니다..

저는 주로 두 가지 등급의 알루미늄 합금 소재를 사용해 왔습니다., 두 가지 자료를 분석하겠습니다., the choice of aluminum alloy materials.

The first one is the 5000 시리즈 알루미늄 합금, which is mainly used for sheet metal structural parts. 그만큼 5000 series aluminum plate belongs to the more common alloy aluminum plate series. The main other elements are magnesium, 마그네슘 함량은 3-5%. 알루미늄-마그네슘 합금이라고도 함.

The main features are: 낮은 밀도, 높은 인장 강도 및 높은 연신율. The density is lower than other series of aluminum alloys. 가공 기술은 연속 주조 및 압연입니다., which belongs to the series of hot rolled aluminum sheets. Mainly in China's 5000 series aluminum plate is one of the more mature aluminum plate series.

Often used is the 5052, which has good molding processability, 내식성, 용접성, 피로 강도, medium static strength, used in the manufacture of aircraft tubing, 연료 탱크, 냉간 가공 경화시 가소성이 낮습니다., 낮은 자동차 경량화의 개발을 달성하는 것은 큰 의미가 있습니다.

The second type is the 6000 길이 x 너비 x 두께 x 밀도, which are mainly machined parts. Unlike the 5000 시리즈, 그만큼 6000 series alloys are added with silicon, so that the hardness of the 6000 series aluminum alloy is greatly improved, and the machining performance is very good. It is also suitable for applications where corrosion resistance and oxidizing requirements are high. Easy to layer, 고강도 및 강한 내식성. I often use 6061 aluminum alloy for machined parts, and the cutting performance is good (5000 series is not good).

Let me talk about the aluminum alloy status code:

에프: free processing state (uncommon)

영형: Annealing state (the mechanical professional should know, I also sigh here, annealing refers to slowly heating the metal to a certain temperature, for a period of time, and then cooling at a certain speed. This can reduce the material. 경도, improve the cutting process performance, eliminate residual stress, stabilize the size, it is not easy to crack when the sheet metal is bent. Simply speaking, the aluminum alloy O state is soft and soft.

시간: 가공 경화 상태 (가공 강화, also knowledge in heat treatment courses, 경도, 힘, wear resistance increased, not easy to process)

티: heat treatment state (T code must be followed by one or more digits, is a stable state product)
