    Comprendre les propri\u00e9t\u00e9s de la plaque d'aluminium 7075<\/h2>\n

    7075 plaque d'aluminium<\/a> stands out for its exceptional strength, good machinability, and moderate corrosion resistance. It is heat-treatable and available in several tempers, each offering a different balance of strength, toughness, and stress-corrosion resistance.<\/p>\n

    Chemical Composition of 7075 Aluminum Plate<\/h3>\n

    The strength of 7075 comes from its zinc, magnesium, and copper content. The alloy conforms to AMS specifications and ASTM B209 standards.<\/p>\n
