About Aluminum Silicide AlSi2 Powder:
Aluminum silicon alloy (aluminum-silicon alloy) is forging and casting alloy with aluminum and silicon as the main components. Generally, the silicon content is 11%. At the same time, a small amount of copper, iron, and nickel are added to increase the strength. The density is about 2.6～2.7. g/cm3, thermal conductivity is about 101～126W/(m·℃), Young’s modulus is 71.0GPa, impact value is about 7～8.5J, fatigue limit is ±45MPa.
Due to its lightweight, good thermal conductivity, and certain strength, hardness, and corrosion resistance, AI-Si alloys are widely used in the automotive industry and machine manufacturing to make parts that are used under sliding friction conditions.
The aluminum-silicon alloy forms a binary eutectic in 11.7% of silicon with a melting point of 577°C. The two phases are silicon solid solutions in aluminum, with a maximum solid solution of 0.8% at room temperature, and aluminum solid solutions in silicon. There are no intermetallic compounds. Sodium can be added in small amounts to improve the eutectic and increase the strength by improving the hardening of the dispersion. Even small amounts of iron can severely reduce toughness, although manganese can be added to reduce this effect.
Al-Si alloy is a very important industrial alloy. Aluminum silicide is widely used in aviation, transportation, construction, automobile and other important industries. It is also used to manufacture low and medium-strength castings with complex shapes, such as cover plates, motor housings, and brackets. Racks, etc., are also used as brazing solder. The alloy is a typical eutectic alloy with a simple phase diagram and no intermediate compounds are produced. It has the advantages of good casting performance, high specific strength and low price. Aluminum is an element of the third main group, and silicon is a semiconductor element, and the solid solubility between the two is very small.

How is Aluminum Silicide AlSi2 Powder produced?
The alloy temperature of the electrothermal method for producing aluminum-silicon alloy is about 2000°C; during the metallurgical process, alumina and silicon oxide are in liquid form and are generally reduced with a carbonaceous reducing agent; the maximum temperature that the submerged arc furnace can generally reach is about 1350~ Around 2200°C.
Applications of Aluminum Silicide AlSi2 Powder:
When the silicon content is low (such as 0.7), the ductility of aluminum-silicon alloy is better, and it is often used as a deformed alloy; when the silicon content is higher (such as 7%), the filling of the aluminum-silicon alloy melt is better, and it is commonly used for making Cast alloy.
In aluminum-silicon alloys with silicon content exceeding the Al-Si eutectic point (silicon content of 12.6%), when the silicon particle content is as high as 14.5% to 25%, adding a certain amount of Ni, CU, Mg and other elements can improve Its comprehensive mechanical properties.
They can be used in automobile engines instead of cast iron cylinders to significantly reduce weight. The aluminum-silicon alloy used in the cylinder can be electrochemically treated to etch the surface aluminum and retain the primary silicon dots embedded in the substrate on the inner wall of the cylinder, and its scratch resistance and wear resistance can be significantly improved.
Among them, the alloy with a silicon content of 11% to 13% has become one of the best piston materials due to its lightweight, low expansion coefficient and high corrosion resistance.
