What Is 7175 Aluminum?<\/h2>\n

7175 is a high-strength 7xxx alloy designed for superior toughness \u2014 often favored over 7075 where fracture resistance matters more than peak strength. Linsy supplies 7175 plate, bar and tube in T74, T7452 and T7454 tempers with full MTC documentation for aerospace and high-stress applications. Its improved toughness helps it perform under stress and impact, making it a common choice for forged and machined aircraft parts.<\/p>\n

T74 \/ T7452 \/ T7454<\/strong> \u2014 overaged tempers that maximize toughness and stress-corrosion resistance; T7452 is for die forgings, T7454 for hand forgings. Choose based on form and toughness needs.<\/p>\n

Caract\u00e9ristiques principales<\/h2>\n

High Toughness<\/h3>\n

Better fracture resistance than 7075 at slightly lower strength.<\/p>\n

Bonne usinabilit\u00e9<\/h3>\n

Machines well in overaged tempers.<\/p>\n

Soudabilit\u00e9 limit\u00e9e<\/h3>\n

Not recommended for fusion welding.<\/p>\n

Applications<\/h2>\n

Aircraft structural forgings, gears and shafts, high-stress machine parts, automotive and aerospace components.<\/p>\n

Remarques concernant le traitement et la finition de surface<\/h2>\n

CNC machining supported; anodizing available. Overaged tempers machine more predictably than T6.<\/p>\n
