Machinability of Al 7050 is good as it is mostly present in the form of bars, sheets, and plates for commercial applications.

Al 7050 Cost

Cost of Al 7050 is high as it has main use in aerospace industries because of extraordinary, corrosion resistance and strength.

Aluminum 7075

Material 7075 is another common aluminum alloy. It has Zn main alloying agent. Other elements that are present are Mg, Cu, Fe, Si, Ti, Mn, Cr and other elements in minute amount. It is normally present in heat treatment which is tempered state. Al 7075 t7351 and t7451 aluminum are its common tempered grades. Fatigue strength of material 7075 is remarkable. However, machinability is low as compared to 7050. Low corrosion resistance is also a drawback in material 7075. The cost of material 7075 is relatively high. This limits its applications in many fields as compared to other aluminum alloys.

7075 aluminum properties

Strength and deformation resistance are high in material 7075. These features are good for heavy duty applications. Fatigue failure can occur in this material which can result in breaking of material. This occurs due to micro fractures. Other mechanical properties are reasonable of material 7075. The aerospace industry mostly uses this material 7075 for making different components and parts.

Aluminum 7050 t7451 properties

T7451 aluminum is a heat-treated material 7075 which has undergone tempering. Properties of T7451 aluminum are reasonable. The table below shows the properties of T7451 aluminum.

What is 7050 Aluminum used for?

Al 7050 has the most applications in aerospace industries due to its light weight and high strength. Military vehicles are also made of Al 7050. Corrosion resistance is also good for harsh environments applications. Al 7050 is the best option for heavy plate applications. Fuselage frames and wing skins of aircraft are mostly made by using this material. Al 7075 T7351 & T7451 aluminum are common heat-treated grades used for aircrafts applications. 7050 t6 Aluminum is also a common heat-treated aluminum alloy used for making aircraft and military parts.

7050 Aluminum Bar

Al 7050 bar is utilized for aircrafts. It has high stress corrosion resistance and strength. High toughness makes it suitable for heavy plate applications. It is less quench sensitive and can retain its strength in thicker components of bars. Electrical conductivity is high in Al 7050.

7050 Aluminum tubing

Al 7050 tubing has higher strength. It possesses high corrosion resistance and higher fracture toughness. 7050 aluminum tubing utilizes in aerospace applications. 7050 aluminum tubing is mostly present in 2 categories: Al 7050 extruded and Al 7050 drawn tubing. Extruded ones are extruded by dies and present as seamless product. Drawn products are also extruded but final product is drawn by die.

Al 7075 t7351 plate

Al 7075 t7351 plates are same as the material 7075. It is less sensitive to quenching and can maintain strength for long time. High corrosion, scratch resistance and greater toughness make it useful for aircrafts applications. Wing skins are mostly made by Al 7075 t7351 plates.
