is the act of deterioration in metals.[1] A chemical reaction occurs between the metal and it’s environments Eg. Copper + Oxygen ( Copper Oxide Cu (I) + O ( CuO Rust is very similar to corrosion but only occurs in iron and steel (an iron alloy). Rust is formally known as oxidation‚ which occurs when Oxygen (O) comes into contact with iron (Fe). Overtime‚ the oxygen reacts and combines chemically with the iron‚ forming a substance named Iron Oxide (Fe2O3)‚ which weakens the physical bond

Research on Magnet materials • Alnico Magnets Alnico magnet alloy is largely comprised of Aluminum‚ Iron‚ Cobalt and Nickel. Alnico is a moderately expensive magnet material because of the Cobalt and Nickel content. Alnico magnet alloy has high maximum operating temperature and a very good corrosion resistance. Some grades of Alnico alloy can operate upwards of 1000C. Magnets made with this alloy are available in a variety of grades and dimensions and they are usually cast. Alnico magnet material
