What is aluminum sheet for car door

車のドア用アルミニウム板とは、車のドアの製造に特別に使用されるアルミニウム合金板を指します。. 自動車の軽量化トレンドの進展に伴い、, aluminum alloy is widely used in modern automobile manufacturing industry due to its characteristics of light weight, high strength and good corrosion resistance, so as to replace traditional steel, thereby reducing the weight of the car, 燃費の向上, reducing emissions, and maintaining or enhancing the safety performance of the vehicle.

Commonly used aluminum sheet alloy grades for car door include 5182 そして 6061 アルミシート. These materials not only have good formability and corrosion resistance, but also are suitable for stamping, welding and other processing processes to ensure the integrity and safety of the door structure. 例えば, 5182 アルミシート is often used for door panels that require high corrosion resistance and good formability, その間 6061 aluminum sheet is suitable for parts that require higher strength in the door structure due to its excellent mechanical properties and weldability.

Car doors made of aluminum sheet can effectively reduce the weight of the car body, thereby reducing energy consumption, improving the overall environmental performance and economy of the vehicle, and also meet the high standards of modern car design for safety, environmental protection and energy saving.

Parameters of aluminum sheet for car door

Why are 5182 そして 6061 common aluminum sheet for car doors?

その理由 5182 そして 6061 aluminum sheets are often used in car doors is mainly because of their unique performance characteristics, which perfectly meet the strict requirements of automobile manufacturing for materials, especially in terms of lightweight, 安全性, durability and processability.

の特徴 5182 アルミシート

• High strength and plasticity balance: 5182 に属します 5 シリーズ アルミニウム - マグネシウム合金, 優れた機械的強度と延性を備えています, 複雑なスタンピングや成形時に亀裂が入りにくくなります。, 車のドアの複雑な形状にも適しています.
• 優れた耐食性: The magnesium component makes it have better corrosion resistance under various environmental conditions, which is especially important for car doors exposed to the outside for a long time.
• Good weldability: Suitable for welding processing, which is very critical for structural connection during the assembly process of car doors.
• Coating adaptability: Good surface treatment performance makes the coating have strong adhesion, which can effectively protect the car door from external erosion and improve the appearance quality.

の特性 6061 アルミシート

• Medium strength and toughness: 6061 6系アルミニウム・マグネシウム・シリコン合金です。. 熱処理後, 良好な靱性を維持しながら高い機械的強度を得ることができます。. 重量や大きな力に耐える必要があるドア構造に適しています。.
• Comprehensive processing performance: 加工が簡単, cut, drill and weld, suitable for fine manufacturing processes, which is very beneficial for door structures that require precise assembly.
• 優れた耐食性: Although the corrosion resistance is slightly inferior to 5182, it can also achieve a good anti-corrosion effect after anodizing.
• Stability and durability: Stable performance under different temperatures and environments, ensuring the reliability and durability of the door for long-term use.

要約すれば, 5182 そして 6061 アルミシート have become ideal materials for automobile door manufacturing due to their comprehensive advantages in strength, processing, 耐食性, 等, meeting the multiple requirements of automobile lightweight, safety and aesthetics.

 

Typical cases of aluminum sheet for car doors

Early examples for aluminium sheet doors realized using the traditional steel design concept are the front doors of the Renault Espace and the Renault Vel Satis. The only adaptation to the new material is the window frame which is a properly bent extruded aluminium section.

Compared to a steel door, the aluminium door shows a substantial weight reduction (37 %).

For the outer panel, the AlMgSi alloy EN AW-6016 is used, the alloy for the inner panel is EN AW-5182.

An example of analuminium sheet shell concept without a separate window frame is the door of the Audi A2. The outer panel has been produced from the alloy EN AW-6016
(Anticorodal®-121), the inner panel and the reinforcements from Ecodal®-608 (EN AW-6181A).

A technical limitation in early aluminium sheet shell door designproved to be the limited formability of the standard aluminium car body sheet alloys compared to that of deep drawing steel grades. In particular for doors of upper class vehicles, a large drawing depth is required for the inner panels.Using standard stamping procedures, the consistent realization of such high drawingdepths presents someproblemswith the available standard car body aluminium alloys in large series production. Nevertheless, the fabrication of aluminium inner door panels with larger drawing depths is possible, but asks formore complex and closelycontrolled (and therefore more expensive) stamping procedures.

An alternative, but also expensive option is the application of special forming methods, 例えば. superplastic forming. The inner front door of the Maybach shown below has been made from superplastically formable EN AW-5083 (Formall®-545) using a forming temperature of 515 ℃. The initial sheet thickness was 1.6 mm in case of the inner door panel and 3.0 mm for the reinforcement panel. The forming time was about 20 分.

A modern example for an all-aluminium door is the door of the Mercedes-Benz CLS.The door of the CLS coupe is designed without a window frame. It includes an inner door sheet panel reinforced with aluminium extrusions.
