7075-T651 aircraft aluminum plate refers to the state of 7075 aluminum alloy after solution treatment and then artificial aging treatment.
In this state, 7075 aluminum alloy has good strength and corrosion resistance, and is suitable for aerospace and high-end machinery fields.
7075 T651 aluminum plate is a high-strength, heat-treatable aluminum alloy belonging to the Al-Zn-Mg-Cu series. "7075" represents the alloy number, while "T651" refers to the state of the alloy after a specific heat treatment and pre-stretching process (Temper 6, Stretch 1). This process not only improves the strength and toughness of the material, but also enhances its resistance to stress corrosion cracking.
7075 T651 Aircraft Aluminum Plate has the following notable characteristics:
High strength: As one of the strongest commercial alloys, 7075 T651 Aircraft Aluminum Plate is much stronger than mild steel and is one of the best performing aluminum alloys.
Its tensile strength can reach 572MPa and its yield strength can reach 503MPa, making it suitable for high-stress structural parts.
Good mechanical properties: In addition to high strength, the alloy also has good mechanical properties, including wear resistance, fatigue resistance and impact resistance.
Easy to process: Although it has high strength, 7075 T651 Aircraft Aluminum Plate has good processability and is suitable for various complex machining operations such as cutting, drilling, bending, etc.
Good corrosion resistance: Through proper heat treatment and surface treatment, 7075 T651 Aircraft Aluminum Plate can effectively resist general corrosion and extend its service life.
Top Metal provides sheets with a maximum width of up to 3800mm and a maximum thickness of 250mm, as well as sheet up to 2650mm wide and as thin as 0.2mm, meeting various orders' thickness and width requirements.
