2000 Series Aluminum Alloy

The 2000 series aluminum alloy has a strength similar to that of steel and excellent corrosion resistance. It typically contains 2%-10% copper and is often used to make lightweight, high-strength, high-temperature, low-temperature oxidation-resistant, and corrosion-resistant products.

The 2000 series aluminum alloy has excellent strength and toughness, as well as good machinability and corrosion resistance. It is considered a superhard aluminum alloy that can be strengthened by heat treatment. It is commonly referred to as aviation aluminum alloy along with the 7000 series aluminum alloy.

From precision screws and precision parts to aircraft body materials, common 2000 series aluminum alloys include 2024, 2014, 2219, and 2618.

Applications

2000 series aluminum is a typical hard aluminum alloy in the aluminum-copper-magnesium series and is one of the most widely used hard aluminum alloys. It has high strength, excellent mechanical properties, corrosion resistance and weldability. The formability in heating state, annealing state and quenching state is relatively good, and the heat treatment strengthening effect is significant, but the heat treatment process requires strict control. Cracks are easy to occur during welding, but special techniques can be used for welding and riveting.

2000 series aluminum widely used in aircraft structures, rivets, truck wheel hubs, automotive machinery parts manufacturing, propeller components and other structural components.

Aerospace

The 2000 series aluminum-copper alloy is popular used in aircraft structures, like skin, skeleton, ribs, partitions, due to its high strength and fatigue resistance, especially in tension areas of wings and fuselage structures.

Although its corrosion resistance is poor, it can be effectively protected by pure aluminum coating. but the Alclad Sheet of pure aluminum cladding can make the material get effective protection and enhance the corrosion resistance.
