What is the main alloying element of 7000 aluminium?

7000 series commercial aluminium alloys utilise zinc as the principal alloying element; when combined with a smaller amount of magnesium, the result is a heat-treatable alloy which offers very high strength.

Is 7075 stronger than steel?

Alloy selection is important for extrusion projects, and in the aerospace industry, the 7075 aluminum alloy is commonly used. With zinc as it’s primary alloying element, it is exceptionally strong. A member of the 7000 series, it is one of the strongest alloys available and is comparable to many types of steel.

What is the difference between T6 and T7 aluminum?

The T6 tempers and variants like T651 are rated C for stress corrosion but are the highest strength. The T73 tempers are a bit lower in strength but earn a B rating for stress corrosion resistance. Perhaps the most widely used high strength alloy in aerospace applications.

What is the 7000 series aluminum?

In fact, these 7000 series alloys belong to the super hard aluminum. And they are the perfect material for the aerospace field. In addition, the 7000 series aluminum is better material of vehicles, sheet metal parts, molds, precision instruments and other high-performance requirements of the conditions.

What are the advantages of 7000 series alloys in the industry?

Its strength even reaches about 2/3 of the strength of industrial A3 steel, but only need 1/3 of the weight of A3 steel, which is one of the important reasons that it is popular in the customers. 2.For the electronics industry, 7000 series alloys are very good metal materials.

Is 7075 aluminium suitable for anodising?

Grade 7075 aluminium is suitable for protective anodising & hard anodising. If colour anodising is required, only dark colours should be considered. 7075 aluminium alloy is unsuitable for bright anodising, however it is perfectly suited to powder coating.

What are the different grades of aluminium?

Known as the zinc grades – zinc being the largest alloying element, the 7000 series grades are the hardest and strongest commercial grades of aluminium. Grade 7075 is the most common of the 7000 series grades.
