AMS 4092 Aluminium Alloy – Composition, Properties and Uses.

AMS 4092 Aluminium Alloy

In the aerospace and aviation industries, materials used in manufacturing must meet strict standards and specific requirements. AMS 4092 is a widely used material in the aerospace and aviation industries. The material has to undergo several tests and evaluations before being approved for use in the industry. This blog post will discuss AMS4092 in detail, including its composition, physical and mechanical properties, uses, hardness, and heat treatment.

What is AMS 4092?

AMS 4092 ( also known as Aluminium 6061) may sound complex, but it is pretty simple to understand. It is a specification developed by the Society of Automotive Engineers (SAE) to define the requirements for high-performance engine oil. Specifically, AMS4092 outlines the minimum standards a turbine engine oil must meet to be considered suitable for aircraft engines. This specification considers viscosity, volatility, and other performance-related characteristics to ensure that only the highest quality oils are used in aircraft engines. By adhering to the standards outlined in AMS4092, aircraft operators can rest assured that their machines will perform reliably and efficiently, even in the most demanding conditions.
