High Purity Silicon Aluminum Alloy Si-Al Powder

High-silicon Aluminum Alloy is a binary alloy composed of silicon, aluminum, and other elements. This is an alloy that is used primarily in portable electronic devices, aerospace technology, and space technology.

About Silicon-Aluminum Alloy SiAl Powder The high-silicon-aluminum alloy powder is an alloy binary composed of silicon-based and aluminum-based metals and is used as a thermal management material. High-silicon aluminum material is able to maintain excellent performance and has a high content of aluminum and silicon. Silicon powder can be prepared with a mature technology at a low price. The material is non-toxic to humans and the environment. What is the purpose of adding silicon to aluminum?
Addition of silicon to aluminum results in a more fluid metal alloy, without the metal breaking down at high temperature. The silicon lowers the melting point of aluminum. As there is no brittleness, the aluminum will not suffer from hot tearing.
The density of aluminum alloys with high silicon content is between 2.42.7g/cm3 and the coefficient thermal expansion (CTE), is between 7-20ppm/. Increasing the amount of silicon in the alloy can reduce its density and thermal coefficient. High-silicon Aluminum Alloy has good thermal conductivity as well. It also has high specific strength and stiffness. Silicon Al Alloy Powder is a global supplier of Silicon Al Alloy.

What is Silicon Aluminum Alloy Si Al powder ?
Preparation of silicon and aluminium alloy
(1) no pressure infiltration method
To prepare composite materials, melt the aluminum alloy into the silicon prefabricated part to help with the permeability of carbon steel in the air.
(2) Pressure infiltration method
Applying an external force causes liquid aluminum to penetrate into the preforms of silicon powder. This will promote penetration, wetting and recombination. The normal procedure is to first prepare the prefabricated reinforcements of silicon particles and then cast the composites permeable.
(3) vacuum hot pressing method
Pressure forming and pressure silting are carried out simultaneously in vacuum conditions.
(4) Method of powder metallurgy
The method for making a mixture of silicon powder, aluminum powder, and binder using injection, dry pressing and other methods, then sintering it in a protected atmosphere to get a dense product;
(5) rapid Solidification Method
Also known as rapid cooling, increasing the cooling rate can increase the solidification temperature and speed, thereby improving the microstructure.

Application for Silicon Aluminum Alloy Powder Si-Al:
1) High-power integrated chip packaging: aluminum alloy with high silicon content provides efficient heat dissipation.
2) Carrier : It can act as a localized heat sink, allowing the components to be arranged more closely.
3) Optical Frame: Aluminum alloy high-silicon provides low thermal coefficient, high rigidity, and machinability.
4) Heat sinks: the high-silicon aluminum alloy is effective at dissipating heat and providing structural support.
Silicon Aluminum Alloy Si Al powder in automotive parts
This high-silicon aluminum alloy (with a silica content of 20-35%) has excellent tribological characteristics and can be widely used as a lightweight, wear-resistant advanced material for various transportation vehicles, machines, tools, fasteners, and tools.
High-silicon aluminium alloys have a number of advantages including small specific weights, lightness, good thermal conductivity with low thermal expansion coefficients, volume stability, wear resistance and corrosion resistance. They are widely used for cylinder sleeves, brake discs, rotors in automobile engines and other materials.

Storage condition of Silicon Aluminium Alloy Powder Si-Al:
Si-Al powder will not perform well if it is exposed to dampness. Therefore, you should store the silicon aluminum powder in a dry and cool room. It is also important to avoid putting the silicon alloy powder under pressure.

Packing & Shipping Silicon Aluminium Alloy Powder Si-Al Powder :
The packing we use depends on the amount of Si-Al alloy powder.
Silicon Aluminum Alloy Si-Al Powder Packing: Vacuum packing, 100g/bag, 500g/bag, or 1kg/bag. 25kg/barrel.
Once payment has been received, the powder can be shipped by air, sea, or express.
