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

About Silicon-Aluminum Alloy SiAl Powder High Silicon Aluminum Alloy Powder is a binary powder composed of aluminum, silicon and metal. The high-silicon aluminium alloy material is able to maintain the excellent performance and content of aluminum and silicon. Silicon powder can be prepared with a mature technology at a low price. The material is non-polluting and harmless to humans. 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, while 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. a global Silicon Al Alloy Powder supplier. Please feel free to contact us at any time for the latest Silicon Aluminum Alloy price.

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 powders. This will promote penetration, wetting and recombination. It is usual 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 specific proportion of silicon powder, aluminum powder and binder using dry pressing or injection methods and other methods in order to create powder mixing molding and sintering under a protective environment to obtain a dense product;
(5) rapid Solidification Method
Also known as rapid cooling, increasing the solidification cooling speed will increase the solidification rate. This is done to improve the microstructure of an alloy.

Application for Silicon Aluminum Alloy Powder Si-Al:
1) High-power packaging for integrated circuits: aluminum alloy with high-silicon provides efficient heat dissipation.
2) Carrier: This can be used for a local 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.
Heat sink parts - high silicon aluminium alloys provide effective heat dissipation as well as 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 in various transportation vehicles, as well as various types of machine 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, pistons of automobiles and other materials.

Storage condition of Silicon Aluminium Alloy Powder Si-Al:
Si-Al powder will not perform well if it is exposed to damp conditions. Therefore, the silicon aluminium alloy powder must be packed in vacuum bags and kept 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 or 25kg/barrel or as per your request.
Once payment has been received, the powder can be shipped by air, sea, or express.
