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.
Designation system for the alloys and the heat treats
nxxx-wrought alloys
nxx.x-casting alloys
F-as fabricated
O-Annealed
H-Cold Worked
W-Solution treated
T-Age hardened
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.
Titanium alloys
good corrosion resistance, specific strength. good at high temperatures. used in prosthetics.
