What exactly is Aluminium Silicon Alloy (Aluminium-Silicon Alloy)?
Silicon-aluminum alloy is a combination of silicon, aluminum and magnesium that has the ability to retain their outstanding properties.
Silicon is excellent in casting metal alloys. Because of its melting temperature and fluidity it can reduce shrinkage and solidification time and is also inexpensive as a raw material. Silicon also has a very low density (2.34g/cm3). This could be an advantage when it comes to reducing the total weight for casting parts. It has a very low solubility when it comes to aluminum. Silicon is precipitated in the hard form of nearly pure silica, which increases wear resistance. It is very high in aluminum and silicon, and has an advanced preparation technique.
The Si-Al alloy’s density ranges between 2.4g/cm3 and 2.7g/cm3 and the coefficient of thermal expansion (CTE) is between 7-20ppm/. As the silicon content increases Si-Al alloy’s density as well as thermal expansion coefficient drop dramatically. However Si-Al alloy is characterized by excellent properties, like excellent thermal conductivity, excellent specific strength and stiffness. It also has a good coatings with silver, gold, copper and nickel, weldable with substrate, easy precision machining and so on.
Silicon-aluminum alloy is an exciting electronic packaging material, particularly in high-tech fields such as aerospace, space technology, and electronics that can be carried around.
What are the Types of Silicon Aluminum Alloys?
The industrial alloy of silicon-aluminum is divided into four groups:
Hypoeutectic silicon aluminum alloy. The silicon content varies from 9 – 12 percent..
Eutectic silicon aluminum alloy. The silicon content ranges between 11% and 13%.
Hypereutectic silicon aluminum alloy. The silicon content varies between 15% and 20%.
High silicon aluminum alloy. The silicon content is higher than 22%, and the majority being between 25-70 percent. It could even be as high as 80 percent.
What is the function of the alloy Aluminium-Silicon Alloy?
The high silicon-aluminum-alloy material is highly tribological and can be utilized for advanced lightweight wear resistance materials like transport tools, power machines, and special fasteners.
High silicon-aluminum alloy is widely used for cylinder liner, piston and rotor of automobile engines. The alloy is low in specific gravity, a low weight, low thermal conductivity, and high volume stability. It also provides corrosion resistance, wear resistance and wear resistance.
It is also suitable for high power integrated-circuit packaging.

Parts to heat sinks
Al-Si alloy can be described as a powerful compound oxidizer. The replacement of pure aluminium in steelmaking can improve the efficiency of the process, as well as clean the iron molten and improve the quality of the product.

What is Silumin?
Silumin is a group of high-strength and lightweight aluminum alloys that are based on the aluminum-silicon systems. The majority of aluminum-silicon alloys comprise 3 to 25 percent silicon. Casting is the primary application of these alloys however, they are also used in rapid solidification process and powder metallurgy. Powder metallurgy alloys could have up to 50% more silicon than those that are used in casting. Silumin is resistant to corrosion which makes it ideal for wet environments.
