Physical
Aluminium is a relatively soft, durable, lightweight, ductile and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. It is nonmagnetic and does not easily ignite. A fresh film of aluminium serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far infrared radiation. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa.Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.
Aluminium atoms are arranged in a face-centered cubic
(fcc) structure. Aluminium has a stacking-fault energy
of approximately 200 mJ/m2.
Aluminium is a good thermal and electrical conductor,
having 59% the conductivity of copper, both thermal and
electrical, while having only 30% of copper's density.
Aluminium is capable of being a superconductor, with a
superconducting critical temperature of 1.2 Kelvin and
a critical magnetic field of about 100 gauss (10
milliteslas).
Chemical
Corrosion resistance can be excellent due to a thin
surface layer of aluminium oxide that forms when the
metal is exposed to air, effectively preventing further
oxidation.The strongest aluminium alloys are less
corrosion resistant due to galvanic reactions with
alloyed copper.This corrosion resistance is also often
greatly reduced by aqueous salts, particularly in the
presence of dissimilar metals.

In highly acidic solutions aluminium reacts with water to form hydrogen, and in highly alkaline ones to form aluminates— protective passivation under these conditions is negligible. Also, chlorides such as common sodium chloride are well-known sources of corrosion of aluminium and are among the chief reasons that household plumbing is never made from this metal.
