In fact, aluminum is known for its ability to resist corrosion well, but it can corrode under certain circumstances. If you guessed that rust was one of the effects of salt water on aluminum, you’d be wrong. Aluminum doesn’t contain iron, however, so it’s naturally protected from rust. Steel, for example, is susceptible to rust because it contains iron. Rust only occurs in iron and other metals that contain iron. Can aluminium be used to prevent rust?Īluminum is rust-resistant, meaning it doesn’t degrade due to oxidation caused by iron and oxygen. You can deposit aluminum on practically any surface (including plastics). Is Aluminium used to protect iron from rusting?Īluminum, just like zinc, is already widely used to coat iron surfaces to prevent corrosion (in the elemental form, or in combination with other metals, like zinc). The following are the two ways to prevent the rusting of iron are: (i) Oiling, painting, or greasing: When we apply oil, grease, or paint, then the surface becomes waterproof and the moisture and oxygen present in the air cannot come into direct contact with iron. What are the two ways to prevent rusting of iron? Water is enemy number one when it comes to rust, because it’s the oxygen in water molecules that combines with iron to form iron oxide. Many outdoor structures, like this bridge, are made from COR-TEN steel to reduce the effects of rust. 6 What can I spray on metal to keep it from rusting?.5 Which is the metal that prevents the rusting of iron?.3 Can aluminium be used to prevent rust?.2 What are 5 ways to prevent iron rusting?.1 How can we protect iron from rusting?.
