Light alloys
Fatigue and fracture mechanics of light-alloy parts

Light aluminum alloys are mainly used in the aerospace industry. They account for some 70% of the materials used in the manufacture of civil aircraft.

Their essential qualities are :

• low density ;

• high electrical and thermal conductivity;

• good corrosion resistance ;

• good aptitude for hot and cold forming;

• good behaviour at low temperatures without risk of embrittlement;

• great curing potential;

• very low toxicity;

• remarkable suitability for all kinds of surface...
