Aluminium's hardness is relatively low due to its low density. This means that it is easier to scratch than other metals like steel are.
DUCTILITY & MALLEABILITY : High
Aluminium is both very malleable, and very ductile. In fact aluminium is the 2ND most malleable metal, and the 6Th most ductile, both of these are very important for its uses.
ELECTRICAL RESISTIVITY : Low 2.65 x 10-8 Ohm metres
Aluminium has a very low electrical resistivity, and therefore a high electrical conductivity.
CORROSION RESISTANCE : High
Aluminium is remarkable for its ability to resist corrosion.sam.davyson.com/as/physics/aluminium/site/properties.html
