Alloys whose main metal is aluminum are called “Aluminum Alloys”. It is also called light alloys. Aluminum alloys can be iron, zinc, silicon, manganese, magnesium, nickel, copper, titan, etc. It is created by adding elements.

Properties;

Conducting heat and electricity well,

Being prone to heat treatments,

It is suitable for casting,

It is light,

It is resistant to chemical effects,

It can be used as a protector in foodstuffs and pharmaceutical industry due to its corrosion resistance and no poisoning hazard.

Partitioning of Aluminum Alloys

Various aluminum alloys are prepared according to the requirements in the areas of use.

Casting Alloys,

Aluminum Alloys that can not be Heat Treated,

Aluminum - Zinc - Copper - Silicon Alloys,

Aluminum - Copper Alloys,

Aluminum - Silicon Alloys,

Aluminum – Magnesium Alloys.

Modification

In aluminum silicon alloys, modification is made by adding 0.01% sodium, in other words, thinning. Strontium is also used for the same purpose.

Grain Refining

Grain refining is performed by adding aluminum titanium boron pre-alloys (Al-Ti-B) to liquid aluminum. It provides improvement of mechanical properties.

Casting Properties of Aluminum Alloys

Fluidity and tensile are an important casting features.

Fluidity

It is fluidity to fully fill the liquid metal mold cavity.

Fluency is influenced by the following factors;

The shape of the spilled part,

The composition and temperature of the metal,

Contact state of the mold and liquid metal,

Features of the mold,

Casting conditions,

Fluency is measured by a spiral experiment. Fluency is low in pure aluminum.

Tensile

Tensile means volume shrinkage. This feature is more in aluminum. The tensile is reduced by making alloys, but aluminum alloys have a higher tensile strength than other metals.

Melting Aluminum Alloys

Management of Melting

In melting aluminum and its alloys, the danger of oxidation and gas absorption should be avoided.

For this, it is necessary to pay attention to the following points in melting:

Liquid metal should not be mixed,

Overheating should be especially avoided,

The materials used must be very clean,

Metal temperature should be measured with pyrometer,

Liquid metal should be poured immediately.

Aluminum Alloys and Classification

The mechanical, physical and chemical properties of aluminum alloys vary depending on the alloying 1 elements and microstructure. Copper, manganese, silicon, magnesium and zinc are the most important alloying elements added to aluminum. Forging alloys have good plastic deformation ability and can be easily shaped. Heat treatment can be applied to a large part of aluminum alloys. According to the American Aluminum Association, aluminum alloys are classified in four digits. This classification is as follows:

1XXX: Pure aluminum. It is generally used in the electrical, chemical, construction and isolation industries.

2XXX: Al-Cu alloys. The main alloy element is copper. Other alloying elements, especially magnesium, can be found and are widely used in the aerospace industry where high strength is desired.

3XXX: Al-Mn alloys. The main alloy element is manganese. Pipes, liquid tanks and architectural applications are used.

4XXX: Al-Si alloys. This group includes silicon (Si) as the major alloying element. Silicon is added to these alloys in amount up to 13.5% in order to decrease their liquidus temperature and to increase their fluidity, since the alloys are used mostly as welding wires or brazing rods. Some of the alloys are used in architectural applications due to their specific dark grey color which they obtain when anodized.

5XXX: Al-Mg alloys. The main alloy element is magnesium. As the magnesium ratio increases, the hardness and strength increase but the ductility decreases. In the construction of machine parts, there are fields of use in shipbuilding industry due to defense industry and especially high corrosion resistance.

6XXX: Al-Mg-Si alloys. The main alloying elements are magnesium and silicon. These alloys, which are highly formable, are often used in the manufacture of extruded parts.

7XXX: Al-Zn alloys. Zinc is the main alloy element, magnesium, chromium and zirconium are additional alloy elements. The 7XXX series is the one with the highest strength of aluminum alloys. It is used in places where aircraft parts are made and other high strength is required such as defense industry. It is used in inflation molds, calibrators of plastic profile machines. It also has an important place in the production of machinery and parts. Prototype can be used instead of steel due to easy workability and high hardness in part production.

8XXX: Lithium/Other alloys. Ni-Fr alloys are used for nuclear energy installations, Fe-Si alloys are used for bottle caps, and Li alloys are used for aerospace applications.
