aluminum alloy types
What are the Types of Aluminum Alloys?

The homogeneous mixture formed by the combination of a metal element with at least another element (metal, nonmetal) is called an alloy. For aluminum to gain some properties, it is alloyed with copper, manganese, silicon, magnesium, and zinc, and similar elements, that is, it is not used in pure form.

As an example, while the tensile strength of aluminum in pure form is 49 MPa, it increases up to 700 MPa when it enters the alloy. While aluminum alloys are classified as chemical, 4-digit (XXXX) numbers are used as notation.

Alloys whose main metal is aluminum are called “Aluminum Alloys”. These are also called light alloys. Aluminum alloys are created by adding copper, zinc, silicon, magnesium, manganese, iron, nickel, titanium, and similar elements.

What are the Properties of Aluminum Alloys?

Properties;

  • being light,
  • thermal and electrical conductivities,
  • being suitable for heat treatments
  • they are resistant to some chemical effects

Aluminum alloys are suitable for casting. Aluminum alloys formed by forging, drawing, and rolling are also prepared. It is used as a preservative in the pharmaceutical industry and foodstuffs as it is corrosion resistant and does not create a poisoning hazard.

In aluminum-based materials, the main important alloying elements are Mg, Si, Zn, and Cu. These elements are added individually or in combination to achieve certain properties in the alloy. Alloys made with aluminum with these elements are important in terms of improving their mechanical properties. Aluminum, which can make alloys with many elements, is the basis of many alloys with this superiority.

The mechanical, physical, and chemical properties of aluminum alloys vary depending on the alloy elements and microstructure. The most important alloying elements involved in aluminum are copper, manganese, silicon, magnesium, and zinc.

As you can see from its aluminum structure, it is a very durable and strong element. For this reason, aluminum alloys also help to produce durable and long-lasting products.

Let’s examine aluminum alloys in detail with you.

How many aluminum alloys are there?

  1. Aluminum – Copper Alloys

These alloys containing 2% – 6% copper are the most common aluminum alloy. Its corrosion resistance is lower than other alloy groups. However, it shows high hardness and strength. The 2024 aluminum series is the most common type of aluminum and is used effectively in aircraft design.

  1. Aluminum – Silicon – Magnesium Alloys

In its internal structure, up to 1.3%, Si and Mg are equal. A small amount of copper, chromium, or lead is added to the aging process to increase corrosion resistance and strength. It is used in the production of screws, machine parts, furniture, and bridge-carrying elements.

  1. Aluminum – Magnesium – Zinc Alloys

Internal structures have 1% – 7.5% zinc and 3.3% magnesium. It can be added to increase the resistance of chrome and copper. These additions negatively affect welding ability. The highest-strength aluminum alloys are in this group. It is common in aircraft parts as a structural material.

  1. Aluminum – Magnesium Alloys

They are known as cast alloys and their high corrosion resistance allows them to be used in the automotive and aircraft industry. It can contain up to 10% magnesium in its composition.

  1. Aluminum – Silicon Alloys

It is used in the construction of vehicles used in sea transportation due to its high resistance against corrosion occurring in salty environments. It is a commonly used casting alloy.

  1. Aluminum – Tin Alloys

The amount of tin in this alloy is 20% -30%. It has high load carrying capabilities. This easy-to-shape alloy is used as a can in the automotive industry, fastener, and packaging industry.

As you can see, aluminum and aluminum alloys are found in materials used in all areas of our lives. That’s why you can safely use aluminum in all areas of your life.
