7050-T7651 Aluminum Alloy Information

Basic Features of 7050 Aluminum Alloy

• Alloy Composition: The primary alloying element in 7050 aluminum alloy is zinc (Zn), with small amounts of magnesium (Mg) and copper (Cu), giving it excellent strength, corrosion resistance, and workability. It belongs to the aluminum-zinc alloy series and is mainly used in aircraft structures, wings, and skin components.
• High Strength and Low Density: 7050 aluminum alloy has high strength and low density, making it suitable for applications where reducing the weight of the aircraft is important.

Heat Treatment Process of T7651 Temper

• Solution Heat Treatment: During the processing of 7050 aluminum, it first undergoes a solution heat treatment process, which involves heating the alloy to a high temperature to allow the dissolved solute to evenly distribute, laying the foundation for subsequent aging treatment.
• Stress Relief: After the solution heat treatment, 7050 aluminum alloy requires stress relief to reduce residual internal stresses from processing or cooling. This process is typically done by heating the alloy to an appropriate temperature, holding it for a certain period, and then slowly cooling it.
• Artificial Aging: After completing the solution heat treatment and stress relief, 7050 aluminum undergoes artificial aging. This process is performed at lower temperatures to stabilize the precipitate phase in the alloy, further enhancing its mechanical properties and corrosion resistance. T7651 temper of 7050 aluminum typically undergoes a longer aging process to ensure that its mechanical properties reach optimal levels.
