ALUMINIUM ALLOY Meaning and
Definition
-
Aluminium alloy refers to a metal composite composed primarily of aluminium and one or more other elements. It is created by combining varying quantities of aluminium with additional metals such as copper, silicon, manganese, magnesium, zinc, or titanium. This fusion results in the formation of a material that exhibits improved properties compared to pure aluminium.
Aluminium alloys are widely utilized in numerous industries, ranging from automotive and aerospace to construction and consumer goods. These alloys offer several advantages, including enhanced strength, corrosion resistance, lightweightness, ductility, and conductivity. The specific combination of elements and their proportions in the alloy determine its unique properties and suitability for different applications.
Various types of aluminium alloys exist, each offering distinct characteristics and applications. For instance, 6000 series alloys are widely used in structural applications due to their high strength and excellent weldability. 5000 series alloys are known for their exceptional corrosion resistance and are commonly used in marine environments. Additionally, some aluminium alloys are heat treatable, allowing them to further improve their strength and hardness through controlled heat treatment processes.
Overall, the versatility and desirable properties of aluminium alloys make them a preferred material choice in numerous industries, providing a balance between strength, durability, and weight for a wide range of applications.
Etymology of ALUMINIUM ALLOY
The word "aluminium" originated from the Latin word "alumen", meaning "alum". It was first coined as "aluminum" by British chemist Sir Humphry Davy in 1807. However, it went through several changes in spelling, and the current spelling "aluminium" was officially adopted by the International Union of Pure and Applied Chemistry (IUPAC) in 1990.
The word "alloy" has its roots in the Old French word "aloi", which referred to the process of combining metals to create a new material. It eventually made its way into English, and the term "alloy" has been used to describe the mixture of metals since the 16th century.
Therefore, when combined, "aluminium alloy" refers to a mixture of aluminium with other metals or elements to create a new material with enhanced properties.
