5182 Aluminum Coil Sheet for Closure Caps
5182 aluminum alloy can lid material is mainly used to make ring pull tabs for pull tab cans. Aluminum cans have the advantages of being lightweight, heat-resistant, conductive, odorless, non-toxic, good in printing, and recyclable. 5182-h19 aluminum sheet/coil is the perfect material commonly used for can lids. H19 tempered 5182 aluminum alloy has the characteristics of light weight, heat resistance, odorless and non-toxic, good printing effect, and high recycling rate. It is widely used in beer and beverage packaging cans.
5182 aluminum alloy is the main alloy for ring pull materials, and 3004, 5052, etc. are mainly used for the bottom of the tank. These alloys are not only used to make all-aluminum cans, but are also widely used in packaging containers such as tinplate cans. With the development of the beverage industry and the replacement of old packaging materials, 5182 aluminum alloy will be more widely used in the packaging market.
Pull tab blanks are generally processed from 5052 and 5182 aluminum alloys, and tab can cover materials are generally processed from 5052 and 5182 aluminum alloys.
5182 aluminum coil is an aluminum alloy that is mainly used to make sealing caps, especially for beverage containers such as bottles and cans. Closure covers need to be lightweight, corrosion-resistant and easy to form, making aluminum an ideal material choice.
- Alloy Composition: 5182 Aluminum alloy typically contains elements such as magnesium, manganese, and chromium, which contribute to its strength and corrosion resistance.
- Strength: 5185 aluminum sheet coils have good strength, which is crucial to maintaining the integrity of the cover during loading, unloading and transportation.

5182 Aluminum Coil Sheet for Closure Caps Manufacturing process
- Casting: The manufacturing process typically begins with casting an ingot or billet of 5182 aluminum alloy. These ingots are then homogenized to ensure uniformity of composition and structure.
- Rolling: The homogenized ingot is then hot rolled into coils of the required thickness. Hot rolling helps achieve the required mechanical properties and surface finish.
- Cold Rolling: Hot rolled coils can undergo further cold rolling to achieve the final thickness and surface finish required for capping applications. Cold rolling also gives the material extra strength and dimensional accuracy.
- Annealing: Cold rolled coils can be annealed, a heat treatment process that helps eliminate internal stress and improve formability.
- Slitting and Cutting: The roll is then slit and cut into sheets or strips of the required size, ready for further processing into closure caps.
- Forming and Stamping: 5182 aluminum sheet or strip is fed into a forming and stamping machine to form closures to specific designs and dimensions.
- Surface Treatment: Upon customer request, closures may receive surface treatments such as coating or printing for branding, decorative or functional purposes.
- Quality Control: Throughout the manufacturing process, strict quality control measures are adopted to ensure that the final product meets the requirements for size, mechanical properties, surface finish and corrosion resistance.
5182 aluminum coil sheet for closures is a carefully engineered material with customized properties and complex manufacturing processes designed to produce high-quality closures that meet the stringent requirements of the packaging industry.
