Corrosion: Reasons and solution - Alumeco

WebThe corrosion resistance of aluminum is due to its tendency to form a compact oxide layer over the surface. The oxide formed offers a high resistance to corrosion. The normal surface film present in air is about 1 nm thick. The film thickness increases at the elevated temperature. The film growth is more rapid in water than in oxygen. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. [26] Aluminium is ductile, with a percent elongation of 50-70%, [27] and malleable allowing it to be easily drawn and extruded. [28] It is also easily machined and cast.
