Aluminum cans are made of two basic types Aluminum alloys which include 3004 and 3104. These alloys are used to achieve strength, light weight and corrosion resistance, which are required for long-living containers for beverages. We also know that the can body is typically formed from a 3004 aluminum alloy, which possess good formability enabling the aluminum to be shaped easily during manufacturing while retaining reasonable strength. The alloy consists of 1% manganese and magnesium hardening the aluminum’s tensile strength and dent resistance.
On the other hand, the 3104 alloy is often used in the can ends and lids as it provides a little bit higher strength than low-strength 3004 and stands up to carbonated beverage pressure. This alloy carries a near-identical blend of manganese and magnesium although the proportions are tweaked in order to enhance rigidity. These alloys allow most of the can body and ends to be lightweight without compromising strength required for both transport as well as storage. Packages in this category even have potential to require less materials. As reported by The Aluminum Association, the weight of aluminum cans has been reduced almost 30% since the 1970s as alloy optimization continues to minimize shipping weights and make a smaller overall impact on environment.
Some types of aluminum for cans cans also undergo anodization, a process which dramatically increases corrosion resistance by providing them with a thin layer of oxide on their surface. This helps prolong the can and make sure there are no reactions between the beverage and your can. Anodization can also impart a sheen to the aluminum, and many brands use this property of anodization as an aesthetic feature.
These aluminum types have a remarkable impact on the environment. Aluminum cans can be recycled an unlimited number of times, and recycling aluminum takes just 5 percent of the energy to make the metal from scratch. This has resulted in a 75% recycling rate for cans, with three-quarters of all aluminum ever produced still in use today. Getting a normal can back to a new can takes roughly 60 days and helps reduce the carbon footprint of beverage packaging.
For instance, suppliers such as Zhenx Industry focus on different varieties of aluminum for cans; each alloy is manufactured so that it meets food and beverage quality requirements. This types of Aluminum give those manufacturers a sustainable, durable, light-weight and eco-friendly alternative to beverage packaging to promote productivity within the supply chain for sustainable and strong flavored containers around the world.
