to protect these alloys against corrosion, different surface pretreatments and various types of coatings can be applied e.g. conversion coating, anodizing or sol-gel. The surface pre-treatments induce various surface modifications such as the modifications of the composition and the oxide layer thickness, and lead to removal of the
The present invention relates to an aluminum alloy for casting, having enhanced corrosion resistance and fluidity as a result of adding silicon (Si), magnesium (Mg), a rare earth element and the like to an aluminum alloy for casting, and to a method for producing the alloy. Particularly, the present invention relates to an aluminum alloy which is an improvement upon casting aluminum
Al-Cu alloys are represented by 2020 and 2024, which are also known as duralumin and super duralumin. These Al-Cu alloys feature excellent strength and cutting properties. Since they contain a large amount of Cu, these alloys have lower corrosion resistance than pure aluminum, so treatment is used in corrosive
