\u00a0 \u00a0 \u00a0 L'alliage d'aluminium 2A14 est un alliage d'aluminium dur, dont l'ancienne qualit\u00e9 est LD10. L'alliage 2A14 a une teneur \u00e9lev\u00e9e en cuivre, une r\u00e9sistance \u00e9lev\u00e9e, une bonne r\u00e9sistance thermique, une bonne usinabilit\u00e9, une bonne r\u00e9sistivit\u00e9, des performances de soudage par points et de soudage \u00e0 la molette, peut \u00eatre trait\u00e9 thermiquement et renforc\u00e9, et a un effet d'extrusion, mais il y a des diff\u00e9rences dans les propri\u00e9t\u00e9s longitudinales et transversales. La r\u00e9sistance \u00e0 la corrosion n'est pas tr\u00e8s bonne, et la tendance \u00e0 la corrosion intergranulaire, \u00e0 la corrosion sous contrainte et \u00e0 la fracture appara\u00eetra dans l'\u00e9tat de vieillissement artificiel.<\/span><\/p>\n
