Different kinds of aluminum understand the right combination of strength, durability, and weight efficiency. The cans are often made of 3004 and 3104 alloys, specifically selected for the part of the can it is to maximize properties. For example, 3004 aluminum is often used for the can body because of its ability to be formed and shaped into the cylinder form without losing strength. It is an alloy and consists of 1% manganese and 1% magnesium, which not only increases tensile strength but also prevents it from deformation (dents) during production and transport.
Finally, can ends and lids are made of 3104 aluminium which has even greater rigidity and strength. The alloy is especially important because the beverage can ends require their high-pressure tolerance supported, since carbonation in soda cans can push internal pressures up to 90 psi. This area is a stronger alloy, so the can holds up under more pressure and provides an effective seal to prevent leaks or bursts. These alloys are customized to ensure cans remain 30% lighter than previous generations — minimizing material use and transportation costs while maintaining quality, The Aluminum Association said.
This variety of aluminum has a major driver — cost efficiency and environmental benefits make it an economical choice in can production. Aluminum Cans:Not only are aluminum can completely recyclable, but also it takes just 5% of energy to make new aluminum from recycled material. This high level of energy efficiency means aluminum cans are one of the most sustainable packaging formats. Aluminum lasts forever, so when you recycle it, the metal keeps its quality and can be used again to make a new can that will be back on store shelves in as little as 60 days. This quick service helps manufacturers reach international sustainability targets, with companies like Zhenx Industry manufacturing quality aluminum alloy that meets industry grades.
So beverage makers can cost-effectively meet all the required safety, durability and sustainability standards that different kinds types of aluminum for cans have. Never has this equilibrium been more important as brands look to offer consumers safe, eye-catching and environmentally friendly packaging in an increasingly competitive market.
