AMS 4062 Aluminum Alloy – Composition, Properties, and Uses

AMS 4062

AMS 4062 is a material specification created by the Aerospace Material Specification (AMS) committee. This specification outlines the materials approved for use in the aerospace industry. This specification is important because it helps ensure consistency and reliability in the industry. This article will discuss what AMS 4062 is, its composition, physical and mechanical properties, and uses hardness and heat treatment process.

What is AMS 4062?

AMS 4062 is a specification standard that outlines the requirements for aluminium-alloy castings used in aircraft and other high-stress applications. Developed by the Society of Automotive Engineers (SAE), this standard serves as a vital reference for manufacturers and designers who need to ensure the safety and reliability of their products. Aluminum-casting alloys are widely used in the aerospace industry due to their exceptional strength-to-weight ratio, durability, and corrosion resistance. By complying with AMS4062, companies can ensure that their castings meet the necessary performance, quality, and safety standards. Whether you’re a manufacturer or an engineer, understanding AMS 4062 is crucial to ensuring the success of your projects.

AMS 4062 Composition

AMS 4062 is a low alloy steel that contains a small amount of carbon, manganese, silicon, and other elements. The primary alloying elements present in AMS 4062 are nickel and chromium. These elements provide corrosion resistance, high strength, and toughness to the material. AMS 4062 is also heat-treatable, meaning heat-treatment processes can modify its properties.

AMS 4062 Physical Properties

AMS 4062 has a density of 7.85 g/cm3, similar to other low alloy steels. Its melting point is around 1410°C, meaning it can withstand high temperatures without melting or deteriorating. Hot or cold working processes can easily form this flexible material.

AMS 4062 Mechanical Properties

The mechanical properties of AMS 4062 depend on the heat treatment process applied to it. In its annealed condition, it has a tensile strength of 880 MPa and a yield strength of 680 MPa. After heat treatment, its tensile strength can be increased to 1310 MPa, whereas its yield strength can increase to 1085 MPa. It also has good toughness properties, making it an ideal candidate for high-stress applications.

AMS 4062 Uses

AMS 4062 sheet is primarily used in the aerospace industry to manufacture structural components. It’s high strength and resistance to corrosion make it an ideal material for use in aircraft landing gears, engine components, and structural frames. Apart from the aerospace industry, AMS 4062 is also utilized in chemical and petrochemical industries, power generation, and heavy equipment manufacturing.

AMS 4062 Hardness

AMS 4062, when annealed, has a Brinell hardness of 205. After heat treatment, its hardness can be increased up to 350. It is also known to have good wear-resistant properties, making it a suitable candidate for high-stress applications.

AMS 4062 Heat Treatment

Heat treatment of AMS 4062 involves a two-stage process. The first stage is called austenitizing, where the material is heated to a high temperature to form austenite. The second stage is quenching, where the material is rapidly cooled to attain the desired mechanical properties. The quenching process involves immersing the material in a liquid, usually oil or water, to cool it rapidly. After quenching, the material is tempered to attain the desired balance of strength, flexibility, and toughness.


AMS 4062 is a crucial material specification in the aerospace industry. Its composition, physical and mechanical properties make it a suitable candidate for use in high-stress applications. Its high strength, corrosion resistance, and wear resistance make it an ideal material for structural components, aircraft landing gears, and engine components. Knowing the heat treatment process for AMS 4062 is important to attain the desired mechanical and thermal properties. This material is an excellent choice for high-quality and reliable applications.
