The high-silicon aluminiu alloy, which is made up of both silicon and aluminum, can be described as a binary alloy. It’s an alloy material that is used mostly in aerospace, space technology, and portable electronic gadgets.
Silicon Aluminum Alloy si-Al powder:
High-silicon alloy powder (also known as high-silicon aluminum alloy) is a binary alloy made of silicon and aluminiu and used for thermal management. This high-silicon alloy can preserve the exceptional performance of aluminum and silicon, while the silicon and magnesium content are very rich. It is cost-effective and has a mature preparation process. The material doesn’t pollute the environment or cause any harm to the human body. Why Silicone is added to Aluminium?
Silicon makes aluminum alloy fluidier by being added to it. It doesn’t break down the metal at high temperatures. It actually reduces aluminum’s melting point. As there is no brittleness in the aluminum, it will not be subject to hot tearing.
The high-silicon aluminium alloy’s density is between 2.2.42.7g/cm3, while the coefficient of thermo expansion (CTE), is between 7.20 and 20ppm/. An increase in the amount of silicon can reduce both the density and the thermal expansion coefficient. However, increasing the amount of silicon can significantly reduce the alloy’s density or thermal expansion coefficient.

How Silicon Aluminum Alloy Si–Al Powder Is it Produced?
The preparation of the silicon and aluminum alloys:
(1) no pressure infiltration method
To prepare a composite materials method, the carbon steel permeability assist in the atmosphere, heat the aluminum alloy and melt it into the prefabricated silicon particles.
(2) method of pressure infiltration
To promote penetration, wetting and recovery of liquid aluminum, liquid aluminum can be applied to the surface of the silicon particles. It is common to first prepare the reinforcements for silicon particles and then cast permeable components.
(3) vacuum hot pressing method
In this process, pressure forming and pressure-sintering are done simultaneously in vacuum.
4 powder metallurgy technique
Method of producing a specific amount of silicon powder, aluminum powder and binder through dry pressing, injection and other methods to make powder mixture molding. Also, the sintering is done under protective conditions to produce a dense material.
(5) quick solidification method
Also called rapid solidification, you can increase the solidification rate and the degree of solidification. This is done to refine the microstructure of an alloy.
Silicon Aluminum Powder for Silicon Aluminum Alloy:
1) High-power integrated Circuit Packaging: High-silicon Aluminum Alloy provides heat dissipation.
2) Carrier – It is a heat sink that can be used locally to ensure components are more precisely arranged.
3) An optical frame is a high-silicon alloy that provides low thermal expansion, rigidity and machinability.
4) Heatsink parts: The high-silicon aluminum alloy is effective in heat dissipation as well as structural support.
Silicon Aluminum Alloy Si Al powder in Auto Parts:
The high-silicon aluminium alloy (with a silicon percentage of 20-35%) is highly tribological and can be used in various vehicles as well as various power equipment, machines tools and other fasteners.
A number of features make high-silicon aluminiu alloy a popular choice for cylinder sleeves, pistons, brake discs, rotors in automobile engines and other materials.
Silicon Aluminum Alloy Silicon Al Powder Storage:
Si-Al powder performance and usage effects can be adversely affected by moisture reunion. Silicon aluminum alloy powder should therefore be kept dry and sealed in vacuum packaging. Additionally, silicon aluminum alloy powder shouldn’t be exposed to stress.
Packing & Shipping Silicon Aluminum Alloy Sil Powder:
Many types of packing are available depending on the amount Si-Al in your silicon aluminum alloy powder.
Si-Al Powder Packaging: Silicon aluminum alloy Si powder packaging, vacuum packing 100g, 500g or one kg/bag, 25kg/barrel and as per your request
Si-Al alloy silicon powder shipping: can be shipped by sea, air or express once payment receipt has been received.
