What materials are used to make drink cans?

A drink can (or beverage can) is a metal container designed to hold a fixed portion of liquid such as carbonated soft drinks, alcoholic drinks, fruit juices, teas, herbal teas, energy drinks, etc. Drink cans are made of aluminum (75% of worldwide production) or tin-plated steel (25% worldwide production).

What grade of aluminum is used for soda cans?

The soda pop cans are typically made from a AA 3004 or 3104, which is aluminum containing manganese and some magnesium. The 3XXX alloys are not heat treatable, and have excellent formability and corrosion resistance. The strip used to form the can probably be purchased from either Kaiser or Alcoa aluminium.

Are soda cans made of Aluminium?

Soda cans are made from aluminum — and trace amounts of other metals, including magnesium, iron, and manganese. Aluminum is made from Bauxite, an ore found mostly in Jamaica and Guinea. These are materials are refined into an aluminum oxide called Alumina.

Why are soft drink cans made from Aluminium?

Processing used aluminum requires about 90% less energy and generates 90% fewer carbon emissions than making new aluminum out of bauxite. Further, unlike PET plastic bottles, aluminum cans can be recycled again and again with no loss of quality. So not surprisingly, aluminum is recycled at much higher rates than PET.

Are cans made of tin or steel?

Cans are made of three different materials: aluminum, tin-coated steel (tinplate) and electrolytic chromium coated steel (ECCS).

Is it safe to drink from aluminum cans?

But, Tetro says, the amounts of chemicals leached from the cans can’t pose a health risk. It concluded that current exposure to BPA through packaging did not pose a health risk to the general population. “Unless you’re drinking dozens of cans of soda a day, the likelihood of aluminum exposure is very low.

What metal are cans made of?

In the U.S., most food cans are made of steel while beverage cans are usually made out of aluminum. Chromium and nickel can find their way out of steel, but the amounts would be miniscule to nil.

Which is the best material to hold carbonated beverages?

While almost all food cans are made of steel, aluminum’s unique properties make it ideal for holding carbonated beverages. The typical aluminum can weighs less than half an ounce, yet its thin walls withstand more than 90 pounds of pressure per square inch exerted by the carbon dioxide in beer and soft drinks.

Why are soda cans made out of aluminum?

Aluminum cans bring packaging benefits as well . They are easily formed, resist corrosion and will not rust. Cans made from aluminum easily support the carbonation pressure required to package soda and withstand pressures of up to 90 pounds per square inch. How are soda cans made?

What kind of metals are in beverage cans?

The bauxite is refined and then smelted, and the resulting molten aluminum is cast into ingots The aluminum base, for beverage cans consists mostly of aluminum, but it contains small amounts of other metals as well. These are typically 1% magnesium , 1% manganese , 0.4% iron, 0.2% silicon, and 0.15% copper.

What do you need to know about carbonated soft drinks?

Diet carbonated soft drinks containing phenylalanine must also include the statement, “PHENYLKETONURICS: CONTAINS PHENYLALANINE,” for individuals who suffer from phenylketonuria, a genetic disorder in which the body can’t process that amino acid. If the phenylalanine level gets too high in these individuals, it can damage the brain.
