AMS 4096 Uses

Due to its high strength, toughness, and fatigue resistance, AMS 4096 is commonly used in the aviation industry to manufacture aircraft parts and components. It produces structural components like wings, engine mounts, and fuselage frames. AMS 4096 is also used to produce landing gears and other high-stress components that require excellent mechanical properties.

AMS 4096 Hardness

AMS 4096 is measured using the Rockwell hardness test, with a typical value of B87. The hardness of the alloy can be further increased through heat treatment processes, which we will discuss in the next section.

AMS 4096 Heat Treatment

Heat treatment is a process that modifies the mechanical and physical properties of metals and alloys. AMS 4096 can be heat-treated to improve strength, hardness, and other properties. The most common heat treatment method for AMS 4096 is T6 heat treatment, which involves heating the alloy to around 495-505°C and then quenching it in water or air—the quenching process results in rapid cooling of the alloy, which increases its strength and hardness. After quenching, the alloy is aged at a lower temperature of around 120-190°C for several hours to complete the T6 heat treatment process.

Conclusion:

In conclusion, AMS 4096 material is a high-strength aluminium alloy widely used in aviation due to its excellent mechanical properties and corrosion resistance. It has a specific composition designed to provide a balance of strength, toughness, and fatigue resistance. The alloy is commonly used to produce structural components and high-stress parts for aircraft.
