High Purity Silicon Aluminum Alloy Si-Al Powder

Silicon Al Alloy Si Al Powder Highsilicon Aluminum Alloy Powder is a binary alloy of aluminum and silicon. It is also a metal-based thermomanagement material. This high-silicon alloy can preserve the exceptional performance of aluminum and silicon, while the aluminum and silicon 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 2.2.4 and 2.5 g/cm3. It also has a coefficient of thermal extension (CTE), which is approximately 7 to 20 ppm/. An increase in the amount of silicon can reduce both the alloy’s density or thermal expansion coefficient. High-silicon alloy aluminum has high thermal conductivity, excellent specific strength, stiffness and welding performance with gold and silver. The material is also weldable to the substrate and can be used for electronic packaging. Lempotee has been a reliable global silicon aluminum alloy Si-Al powder supplier.

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 means to make powder mixture molding. Also, the sintering is done under protective conditions to produce a dense material.
(5) quick solidification method
Rapid solidification also refers to the speed of solidification. The solidification rate and quality can be increased through increasing solidification cooling rates, which is useful for refining the microstructure.

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 advanced lightweight wear-resistant vehicles as well as various power and machine machinery.
A number of features make high-silicon aluminiu alloy a popular choice for cylinder sleeves, pistons and rotors in automobile engines and brake discs.

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 must 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:
