In the arena of high-performance metals, 7050 aluminum stands out as a material of exceptional versatility and strength. Whether for aerospace applications or other precision machining requirements, this alloy has become an indispensable feature in various industrial applications. Below, we look into the intricacies of 7050 aluminum alloy, identifying its primary characteristics and examining its various applications.
Composition of 7050 Aluminum
7050 aluminum belongs to the 7xxx series of aluminum alloys and is well-known for its advantageous strength-to-weight ratio. The composition of 7050 aluminum includes zinc as its main alloying element in addition to other elements of smaller percentages. The development of 7050 aluminum was instigated by the need for a high-strength material having excellent resistance to corrosion, making it a key component in various critical applications.
Notable as a vital alloy for aerospace applications, 7050 aluminum alloy stands out as a heat-treatable product. Known for its outstanding stress corrosion cracking resistance, high mechanical strength, and toughness even at temperatures below zero, this alloy is proven to be essential in the aerospace industry. It is specifically tailored for heavy plate applications, including bulkheads, fuselage frames, wing skins, and various structures that comprise aircraft.
Often available in two tempers, T7451 and T7651, 7050 aluminum alloy possesses and electrical conductivity at 40% of copper, reinforcing its adaptability or applications in which conductivity is a key factor. When working with Aluminum 7050, it is important to approach the welding of this metal with appropriate caution, as the welding process may potentially reduce the inherent strength of the alloy.
For an alloy to qualify as 7050 aluminum, it must possess a particular chemical composition as follows: Aluminum at 89%, Zinc at 6.2%, Copper at 2.3%, Magnesium at 2.3%, and Zirconium at 0.12%. These precise proportions ensure that Aluminum 7050 provides the exceptional combination of durability, resistance, and strength required for aerospace industry applications.
Alloy 7050: The Preferred Choice Over 7075 in Aerospace Applications
When it comes to aerospace applications, Alloy 7050 aluminum plates are often the preferred choice, particularly in the 3 to 6 inch thickness range, outdoing the usage of 7075. This preference is attributable to the excellent strength retention offered by 7050 in thicker sections. At Howard Precision Metals, we stock 7050 T7451 aluminum plate (AMS 4050), which provides superior resistance to stress corrosion cracking (SCC) and exceptional exfoliation corrosion resistance, although at somewhat lower levels compared to 7050 T7651 (AMS 4342).
Notably, 7050 T7451 exceeds alloy 7075 in terms of stress corrosion cracking resistance, corrosion resistance, and toughness. A lower sensitivity to quenching, a characteristic not common in many aerospace alloys, gives 7050 the ability to maintain its strength properties exceptionally well in thicker sections. This alloy also exhibits reliable machinability throughout the thickness of heavier gauges, making it distinct from other high-strength aluminum metal counterparts.
