Deep Drawing Aluminium Circle

Deep drawing aluminium circle with good deep-drawn properties usually have excellent machinability and formability, and can meet the manufacturing needs of various complex shapes of parts. The technical parameters of deep drawing aluminum circles usually include thickness and diameter. Generally speaking, the thickness ranges from 0.17mm to 4.0mm, and the diameter ranges from 80mm to 1600mm. The specific technical parameters will be adjusted according to the actual needs of the product and the manufacturing process. Aluminum circles with good deep-drawing performance are widely used in various fields, such as kitchenware, lamps, cookware, handicrafts and so on. These products usually require beautiful appearance, light weight and certain strength and corrosion resistance, and deep-drawn aluminum circles can meet these needs.

The following are some commonly used aluminum alloy series of deep drawing aluminium circle, which usually have good deep-drawn properties:

• 1000 series aluminum circles (pure aluminum):

– Examples: 1050, 1060, 1070, 1100, etc.

– Characteristics: Good ductility and electrical conductivity for deep-drawn applications.

• 3000 series aluminum circles (aluminum-manganese alloys):

– Examples: 3003, 3004, 3105, etc. Characteristics: Good formability and weldability.

– Characteristics: Good formability and weldability, suitable for deep drawing and corrosion resistant applications.

• 5000 series aluminum circles (aluminum-magnesium alloys):

– Examples: 5052, 5083, etc.

– Characteristics: High strength and good corrosion resistance, suitable for use in marine and automotive industries.

• 6000 series aluminum circles (aluminum-magnesium-silicon alloy):

– For example: 6061, 6063, etc.

– Characteristics: Moderate strength, good formability and weldability, suitable for many industrial applications.

Characteristics of deep drawing aluminium circle are:

• Good formability:

The formability of aluminum alloys is the key to deep-drawing performance, and suitable aluminum alloys should have good ductility and plasticity so that they are not easy to crack or deform during the stamping process.

• Appropriate hardness:

The hardness of the aluminum alloy needs to be moderate to ensure that it can maintain its shape in the deep-drawing process, but not too soft, resulting in a loss of strength in the finished product.

• Uniform thickness:

The thickness of the aluminum circles should be uniform to ensure uniform force during the stamping process and to avoid local weak points.

• Good surface quality:

A smooth surface without defects can reduce the wear and tear of the stamping mold and improve the appearance of the finished product.

• Good corrosion resistance:

In some applications, the corrosion resistance of aluminum alloys is very important, especially for products used in wet or harsh environments.

During the processing of deep drawn aluminum circles, the following points require special attention:

• Die design: Ensure that the die design is reasonable and capable of dispersing the punching force to avoid excessive localized force.
• Lubrication: Using proper lubricant can reduce friction, improve forming effect and prolong the service life of the die.
• process parameters: according to the characteristics of aluminum alloy, reasonably adjust the stamping speed, pressure and stamping sequence to get the best forming effect.
• Heat treatment: In some cases, appropriate heat treatment can improve the deep drawing performance of aluminum alloy.

Choosing the right aluminum alloy and optimizing the deep-drawing process can ensure that the quality and performance of deep drawing aluminium circles meet the needs of specific applications.
