Frequently Asked Questions

What exactly is aluminum?
Aluminum, often spelled aluminium outside of North America, is a silver-colored, lightweight metal. It's abundant in the earth's crust, making up about 8% by weight. Known for its versatility, aluminum is used in various industries, including automotive, construction, and packaging.
How is aluminum made?
Making aluminum involves processing bauxite ore, which contains aluminum oxide. Through the Bayer process, aluminum oxide is extracted from the bauxite, then through the Hall-Héroult process, it's separated into pure aluminum metal using electrolysis. This method requires a lot of electricity, making aluminum production energy-intensive.
Can aluminum be recycled?
Yes, and it's one of the most recyclable materials out there! Recycling aluminum saves around 95% of the energy needed to make new aluminum from raw materials. Plus, aluminum can be recycled indefinitely without losing its quality, making it a poster child for sustainable materials.
Why is aluminum used in cans and foil?
Aluminum's lightweight and resistant to corrosion make it ideal for cans and foil. Its ability to form a protective oxide layer keeps it from rusting, unlike some other metals. Aluminum foil is also great at blocking light, oxygen, and moisture, which helps keep food fresh.
Is aluminum safe for cooking and storing food?
Generally, yes. Aluminum cookware and foil are considered safe for cooking and storing food. However, acidic foods can cause a small amount of aluminum to leach into the food. While this isn't considered harmful in small amounts, some people prefer to use coated aluminum cookware or other materials to avoid this.
How does aluminum impact the environment?
While aluminum itself is not toxic, mining and refining it can have environmental impacts, such as habitat destruction and water pollution. However, its recyclability is a big plus. Recycling aluminum drastically reduces the need for raw material extraction, lowering its environmental footprint.
What are some unexpected uses of aluminum?
Beyond the obvious uses in cans, foil, and construction, aluminum pops up in surprising places. It's in fireworks to create bright white sparks, in personal care products like antiperspirants (as an active ingredient), and even in some medicines as an antacid. Its versatility knows no bounds!
