Overall, 5182 aluminum alloy plays a vital role in the production of various beverage container lids.

Aluminum alloy 5182 is a versatile material that is widely used in manufacturing, particularly in the production of beverage can lids or bottle caps. Aluminum alloy 5182 is a key material in the production of various beverage container lids.

Introduction to 5182 aluminum alloy

5182 aluminum alloy belongs to the 5xxx series of aluminum alloys and is known for its excellent corrosion resistance and weldability.

The "5" in the series name indicates that it contains magnesium as its primary alloying element.

And a "1" means it's strain hardened.

The "82" designation refers to a specific alloy in the 5xxx series.

5182 bottle cap aluminum is an aluminum alloy commonly used in the production of beverage can caps. Due to its excellent formability and corrosion resistance, this aluminum alloy is very suitable for the production of can lid materials. 5182 alloy aluminum is tempered to the H48 state through a heat treatment process, which improves the strength of the alloy.

5182 H48 is mostly used for beverage caps with internal pressure, while 5052 H48 is used for beverage and food caps without internal pressure. Usually 3104 bottle cap aluminum plate is the raw material for manufacturing aluminum can body.

The Specification of Aluminium For Caps Material 5182

Composition of Aluminum Caps Material 5182 Element

• Aluminum alloy 5182 consists primarily of aluminum (Al) as the base metal and contains varying proportions of other alloying elements. Key alloying elements in 5182 include:
• Magnesium (Mg): Magnesium is the primary alloying element in 5182 and is typically present in the range of 4.0% to 5.0%. It gives the alloy strength and corrosion resistance.
• Manganese (Mn): Manganese is added in a small amount, usually around 0.20% to 0.50%, to improve the grain structure and increase strength.
• Chromium (Cr): Chromium is sometimes present in trace amounts to further enhance corrosion resistance.
• Other Trace Elements: Trace elements such as silicon (Si) and iron (Fe) may also be present in small amounts.

Properties of Aluminum Caps Material 5182

Aluminum cap material 5182 has a unique set of properties, tailored to meet the specific requirements of cap manufacturing:

• Formability: 5182 has excellent formability, allowing it to be formed into the complex designs required for bottle caps without compromising its structural integrity. This property is essential to achieve a tight seal and ensure the functionality of the cap during the bottling and sealing process.
• Corrosion Resistance: 5182 contains magnesium, which provides excellent corrosion resistance, preventing closures from degradation due to exposure to moisture, acids and other corrosive substances commonly found in beverage packaging environments.
• Strength: The inherent strength of the alloy and its formability ensure that the cap maintains its shape and structural integrity under the mechanical stresses imposed during sealing, handling and shipping.
• Weldability: Aluminum cover material 5182 is easy to weld using a variety of welding techniques, facilitating the assembly of complex cover structures and ensuring secure closure.
• Surface Treatment: The surface of 5182 cap material can be further enhanced through processes such as coating, printing or embossing to provide branding opportunities, aesthetics and additional protection against corrosion and abrasion.

Processing technology of aluminum cover material 5182

• Deep Drawing: Deep drawing is a common forming process used to form flat sheets of 5182 aluminum alloy into seamless covers with precise dimensions and complex geometries.
• Trimming and Perforating: Trimming and perforating operations are used to remove excess material and create vents or tamper-evident features in the cap.
• Surface Treatment: Surface treatments such as coating, painting, printing or embossing are used to enhance the functionality, appearance and branding of the closure while providing additional protection against environmental factors.
• Assembly: Caps may undergo an assembly process in which liners, gaskets, or other sealing components are integrated to optimize their performance and functionality.
