Typical Physical Properties

Mechanické vlastnosti 7075 Hliníkový plech

Due to 7075 aluminum sheet excellent ratio for weight-to-strength, it can be used in applications involving structural parts that are highly stressed.

It’s a popular choice for use in applications in commercial aircraft components and aerospace and defense equipment. 7075 aluminum sheet always called hliníkový plech letecké třídy.

The weldability of this metal is low, but the formability is great. When forging is used, it’s required that the alloy be placed in temperatures between 700 a 900 degrees F. Afterwards, solution heat treatment should be used.

General welding with 7075 aluminum alloy is not recommended. nicméně, you may get good results when resistance welding alloys. The application of arc or gas welding may reduce the natural corrosion resistance of the alloy.

Typical characteristics of 7075 hliníkový plech

• 7075 aluminum sheet belongs to Al-Zn-Mg-Cu super duralumin, due to high zinc content, 7075 has similar strength to steel, so it has excellent fatigue resistance, 7075 aluminum sheet is a typical letecký hliník
• 7075 aluminum sheet plate is easy to machine, which makes it a popular choice for military aircraft.
• 7075 aluminum alloy can be strengthened by heat treatment and is the strongest heat treatable alloy.
• 7075-T6 is composed of 1.6% měď, 2.5% hořčík a 5.6% zinek. It is commonly used by aircraft manufacturers to strengthen the structure of aircraft. Due to the copper content, its weldability is poor, but it has good machinability.
• Po ošetření roztokem, the plasticity is good, and the strengthening effect of heat treatment is particularly good. It has high strength below 150°C, especially low temperature strength.
• Poor welding performance, prone to stress corrosion cracking. Two-stage aging can improve the stress corrosion cracking resistance of the alloy.
• General welding to 7075 aluminum sheet is not recommended. nicméně, good results may be obtained when resistance welding alloys.
• The application of arc or gas welding may reduce the alloy’s natural corrosion resistance.
• The plasticity in the annealed and just quenched states is slightly lower than that of 2A12 in the same state, and slightly better than that of 7A04. Its stress corrosion performance is better than 7A04.
• 7075 T651 is known as the best product in aluminum alloy. It has high strength and is far superior to mild steel. It also has good mechanical properties and anodic reaction, and is a typical aerospace and military aluminum alloy.

6061 aluminum sheet VS 7075 hliníkový plech

Two of the most popular aluminum sheets for structural applications are 6061 a 7075 hliníkových plechů, but they have many differences.

Chemické složení

6061 aluminum has a higher silicon content, zatímco 7075 alloy has a higher zinc content. 7075 has a slightly higher magnesium content and more copper.

Mechanické vlastnosti

Oba 6061 hliníkový plech a 7075 aluminum sheets can be heat treated. The tensile strength of 7075-T6 is almost twice that of 6061-T6. The shear strength of 7075-T6 is about 1.5 times that of 6061-T6.

Svařitelnost

6061 is solderable, zatímco 7075 is generally considered non-solderable. Pro 6061 hliník, heat treatment and aging treatment are required after welding to restore the welded area to its original T state. 7075 is easy to crack after welding.

Použití

They have many fields of application, but the parts of application are not the same. Například, in the aerospace industry, 7075 is more likely to be used for gears or rods, zatímco 6061 is more likely to be used in more malleable areas.
