The main kinds of aircraft aluminum sheets are 7 series and 2 series aluminum. The typical ones are 7075 and 2014 aluminum sheet. Learn more.

Aircraft aluminum sheet is an an ultra-high-strength deformed aluminum alloy, which is currently widely used in the aviation industry. Compared with ordinary aluminum alloys, aircraft aluminum sheets have higher requirements for strength, hardness, toughness, fatigue resistance, and plasticity.

The aircraft aluminum sheet has good mechanical and processing properties, good plasticity after solution treatment, and good heat treatment strengthening effect. Generally, it has high strength and good toughness below 150°C (or even higher). It is an ideal aviation structural material.

The performance of aluminum cannot meet the requirements of use in most occasions. For this reason, people add various alloying elements to pure aluminum to produce aluminum alloys that meet various properties and uses.

There are many kinds of aluminum alloys used in airplanes. There are mainly two kinds: 2 series(2024, 2017, 2A12,etc.) and 7 series(7075, 7475, 7050, 7A04,etc.). Some 5 series(5a06, 5052,5086,etc.) and 6 series(6061 and6082) are also used in airplanes.

The typical 7 series aluminum alloy is 7075 aluminum sheet which mainly contains zinc and belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy and is a heat-treatable alloy. It is a super-hard aluminum alloy with good wear resistance and good weldability, but poor corrosion resistance.

2014 aluminum sheet is used in applications requiring high strength and hardness (including high temperature), such as heavy aircraft, forgings, thick plates and extruded materials, wheels and structural components.

In China, the manufacturing demand for large aircraft is strongly driving the demand for aluminum alloy materials, especially aircraft aluminum sheet. The C919 large passenger aircraft has received more than 500 orders from more than 20 domestic and foreign airlines, and there are more than 200 orders for the ARJ21-700.

More than 30% of the aluminum alloy materials used in them are its own aircraft aluminum sheets. Welcome to leave message below to get the best price.
