The 2000 Series is often overlooked when it comes to aluminum alloys in favor of more common options like the 6000 or 7000 Series. However, Series 2000 aluminum alloys have unique properties and applications that warrant consideration in a variety of projects. In this article, we will explore what Series 2000 aluminum alloys are, their typical grades, physical and chemical properties, and their application areas.

What is 2000 series aluminum alloy?

2000 series aluminum alloys are hard aluminum alloys, including aluminum-copper alloys and aluminum-copper-magnesium alloys. They are aluminum-containing alloys with copper as the main element. At the same time, for machinability, a small amount of alloying elements such as manganese, magnesium, lead and bismuth are also added. Its disadvantage is the serious tendency of intergranular corrosion.


Typical grades include:

2011 alloy, a free-cutting alloy for aluminum plates, has good machinability and high strength, but has poor corrosion resistance.

2024, is a 4.5% copper alloy prized for its high strength and fatigue resistance.

2000 series aluminum alloy has good cutting performance and corrosion resistance, can be anodized and colored, and is very common in aircraft manufacturing.

Physical and chemical properties

Chemical properties:

  1. Corrosion resistance: 2000 series aluminum alloy has a certain degree of corrosion resistance to environments such as atmosphere, fresh water and sea water, which is mainly due to the protective effect of the oxide film formed on its surface.
  2. Oxidation resistance: In high temperature environments, this alloy has good oxidation resistance and is not prone to oxidation reactions.
  3. Processing performance: It has good cutting performance and can easily perform cutting, drilling, milling and other processing operations.

Physical properties:

  1. Density: Relatively low, about 2.7g/cm³, which makes 2 series aluminum alloys better used in situations with higher weight requirements.
  2. Tensile strength: The tensile strength of 2 series aluminum alloys is usually between 400-500MPa, and the specific value depends on its composition and processing.

This alloy offers high strength, excellent machinability and good corrosion resistance. Additionally, these alloys can be easily heat treated to improve their mechanical properties, making them ideal for structural applications.


2000 series aluminum alloys have a wide range of applications. They are commonly used in the aerospace industry for the construction of aircraft structures and components. In addition, these alloys are used in the automotive industry to produce high performance parts such as wheels and suspension components.

The 2014 alloy is used in the aerospace industry and has high strength. The 2017 alloy is a little lower in strength than the 2014 alloy but is easier to machine. 2618 Aluminium Sheet Alloy for Forging. Superior high temperature strength but poor corrosion resistance. Pistons, moulds for rubber forming, and components for general heat-resistant applications. 2219 Aluminium plate has high strength, good low and high temperature characteristics, and superior solubility, but poor corrosion resistance. Containers for low-temperature applications, aerospace equipment.
