Aluminium alloys are widely used in fabrication. These alloys are composed of aluminium combined with various elements to improve specific properties such as strength, corrosion resistance, and machinability.
There are numerous types of aluminium alloys available for fabrication purposes, each with its own unique properties and characteristics. In this article, we will discuss six common types of alloys that are commonly used by aluminium fabrication companies in UAE.
1000 series (Pure Aluminium):
The 1000 series of aluminium alloys is made of 99% or more pure aluminium. These alloys are known for their excellent corrosion resistance, high thermal and electrical conductivity, and ease of fabrication. Commonly used in chemical processing and food storage, these alloys are ideal when purity is a key factor.
2000 series (Aluminium-Copper Alloys):
The 2000 series includes alloys where copper is the primary alloying element. These alloys are known for their high strength, making them suitable for aerospace applications. They are more challenging to work with due to their reduced corrosion resistance but are essential in structures where strength is paramount, such as in aircraft.
3000 series (Aluminium-Manganese Alloys):
Aluminium alloys in the 3000 series are alloyed with manganese. They are highly resistant to corrosion and are typically used in roofing, siding, and other building materials. These alloys are also used in manufacturing pressure vessels and storage tanks due to their good formability and resistance to stress corrosion cracking.
4000 series (Aluminium-Silicon Alloys):
The 4000 series alloys are known for their low melting points and are often used in welding and brazing. Silicon is the primary alloying element in these alloys, providing excellent wear resistance and low expansion. These alloys are commonly used in the automotive industry for engine components and heat exchangers.
5000 series (Aluminium-Magnesium Alloys):
The 5000 series alloys are alloyed with magnesium, which improves their strength and resistance to corrosion, especially in marine environments. These alloys are commonly used in the production of boat hulls, ships, and offshore structures. Their excellent weldability and corrosion resistance make them ideal for harsh conditions.
6000 series (Aluminium-Magnesium-Silicon Alloys):
Alloys in the 6000 series are versatile and widely used in general structural applications. The combination of magnesium and silicon makes them highly resistant to corrosion and gives them moderate strength. They are used in everything from architectural structures to transportation systems, including bicycles and bridges.
