Aluminum cans have the advantages of light weight, corrosion resistance, good thermal conductivity, tasteless, non-toxic, good printing effect, and beautiful decoration, bringing an elegant visual experience to consumers.
Compared with other can lids, aluminum cans not only have superior performance, but can also be made mechanized and large-scale, are low-cost, pollution-free, and can be recycled.
Rolled aluminum strip made of 5182 type aluminum alloy that has undergone a specific heat treatment state and is specially used to make can lids. 5182-H48 Aluminum Coil Strip has a certain hardness and strength and is suitable for applications such as can lids that require high material performance.
5182 H48 Aluminum Coil Strip is stronger than 5052 H48 Aluminum Coil Strip.
- 5182 H48 Aluminum Coil Strip is mostly used for beverage caps with internal pressure.
- 5052 H48 Aluminum Coil Strip is used for beverage and food covers without internal pressure.

Can lid 5182-H48 Aluminum Coil Strip Applications
In the field of beverage can metal packaging, specifically, 5052 and 5182 aluminum coil strips are mainly used to produce can pull rings, beer caps, beverage caps, beverage caps, beer caps, aluminum can caps, aluminum caps, and pop can caps.
In life, you can find examples of using 5182-H48 aluminum coil tape in various packaging can lids. Here are some common examples:
- 5182 H48 Aluminum Coil Strip for beverage cans: The lids of beverage cans are usually made of 5182-H48 aluminum coil strip. This aluminum alloy has sufficient strength and hardness to ensure that the can lid can effectively seal and protect the beverage.
- 5182-H48 Aluminum Coil Strip for food cans: The lids of some food cans may also be made of 5182-H48 aluminum coil strip to ensure that the lids can resist the impact of the external environment on the food.
- 5182-H48 Aluminum Coil Strip for cosmetic containers: This aluminum coil strip may also be used in the packaging of some cosmetic or personal care products, such as spray head caps for perfume bottles, as it provides sufficient performance to protect the product from the outside pollute.
- 5182-H48 Aluminum Coil Strip for paint bucket lids: In the construction and industrial fields, some paint or chemical bucket lids may use 5182-H48 aluminum coil strip to ensure that they remain sealed and protected during storage and transportation.
These are some examples of can lids that may be made from 5182-H48 aluminum coil strip. Specific applications will vary depending on the nature and requirements of the product, but this aluminum alloy is often chosen for can lid manufacturing as it offers good mechanical properties and corrosion resistance.
Can lid 5182-H48 Aluminum Coil Strip production method
- ingot
- Casting and milling
- Ingot heating
- Ingot hot rolling
- Cold rolling blanking
- The finished product is cold rolled, stretched, bent and straightened, cleaned, coated, cut and packaged.
During the cold rolling process of the ingot, two draw-bending, straightening, cleaning and intermediate annealing treatments were performed.
Can lid 5182-H48 Aluminum Coil Strip processing precautions:
- Ingot heating: Heat the milled 5182 aluminum alloy cast to 540~560℃, keep it for 8~10 hours, and then keep it at 500~520℃.
- Hot rolling of ingots: The 5182 aluminum alloy cast after being released is rolled for 15 to 25 times to a rough material with a thickness of 4 to 6 mm. During the hot rolling process, the uniform heating temperature is always maintained at 465 to 485 ℃, the final rolling temperature of hot rolling is not less than 340 ℃.
- Cold rolling blanking: rolling from 4~6mm to 0.30~0.35mm. During the rolling process, two pull-bending, straightening, cleaning and intermediate annealing are performed. The intermediate annealing temperature is maintained at 390°C.
- The finished product is cold rolled: from 0.30~0.35mm to 0.22mm after 2~4 times of rolling, then bending and straightening, cleaning, coating, slitting, and packaging.
