advantages and limitations of aluminum alloys
|
good specific strength, low density, formed easily,high thermal and electrical conductivity, no ductile to brittle transition at low temperatures. nontoxic. easily recycled. non-ferromagnetic, resistance to oxidation and resistance to corrosion. no endurance limit. low melting temperature. poor at high temperatures. used in cans.

|
magnesium alloys
|
low melting point, corrosion resistant, good specific strength,used in aerospace, poor resistance to fatigue, creep, or wear. hazardous while casting or machining, not very ductle,
|
|
Beryllium alloys
|
lighter than aluminum, stiffer than steel. high specific strength, good at high temperatures, used in aerospace, expensive, brittle, toxic, reactive.
|
|
copper alloys
|
high density, good resistance to fatigue, creep, wear. good ductility, corrosion resistance, electrical and thermal conductivity, easily fabricated. used in electrical wiring and plumbing.
|
|
nickel and monel (and cobalt)
|
good corrosion resistant, easily formed, good at high temperatures. used in jet engines.
