What is the difference between al7075t and Al6061? Guofa metal to help you to analyze.

My client is there, but he is confused. He doesn't know how to choose raw materials between A7075 and A6061. He asked me for help today.

How should I choose? To answer this question, let's first look at the chemical composition tables and compare their advantages and disadvantages.

Zinc is the main alloy element in A7075, and it is the first successful Al Zn mg Cu high strength alloy. It plays a good stress corrosion cracking resistance in sheet products by using the beneficial effect of chromium alloying addition

A7075 chemical composition: 0.40.5 1.2-2.0 0.30 2.1-2.9 0.18-0.35 - 5.1-6.10.20 (5) 0.05 0.15

The main alloying elements are magnesium and silicon in A6061. Its strength is so good, but it has good corrosion resistance, good welding performance, good processability (easy extrusion molding), good oxidation and coloring properties. Scope of application: cross energy tools such as: car luggage rack, doors and windows, car body, etc. zinc is the main alloy element of al7075, but sometimes a small amount of magnesium and copper are added. The superhard aluminum alloy contains zinc, lead, magnesium and copper alloys, which are close to the hardness of steel. Extrusion speed is slower than 6 series, welding performance is good, with good mechanical properties and anode reaction, it has more advantages, but the price is higher than other aluminum, it is more suitable for aerospace.
