Overview of Silicon aluminum alloy Si-Al powder

High silicon aluminum alloy powder is a binary alloy composed of silicon and aluminum, which is a metal-based thermal management material. High-silicon aluminum alloy materials can maintain the excellent properties of silicon and aluminum, and the content of silicon and aluminum is quite rich. The preparation technology of silicon powder is mature and the cost is low. At the same time, this material does not pollute the environment and is harmless to the human body.

Preparation method of new silicon aluminum metal powder

It arranges the silicon steel waste in the production of silicon steel in a reasonable position with the iron core, aluminum iron, high-purity ferrosilicon and industrial pure iron in the vacuum induction melting furnace, which can effectively Avoid the problem that silicon steel waste cannot be melted, thereby effectively improving the conversion rate of silicon steel waste, saving scrap steel resources and improving economic benefits. The silicon-alumina powder is prepared by the above-mentioned preparation method. Therefore, the effective use of silicon steel waste in silicon steel production can effectively increase the added value of scraps in silicon steel production and save production costs. The preparation method of silicon aluminum powder: put silicon steel waste into the outer periphery of the furnace body of the vacuum induction melting furnace to form a waste ring; put the iron core into the furnace body, and place it in the waste circle formed by the silicon steel waste; The high-purity ferrosilicon is arranged below; the aluminum-iron and industrial pure iron are arranged in sequence above the iron core;

Silicon aluminum alloy classification

Industrially important silicon-aluminum alloys can be divided into four categories:

(1) Hypoeutectic silicon aluminum alloy contains 9% to 12% silicon.

(2) Eutectic silicon-aluminum alloys contain 11% to 13% silicon.

(3) The silicon content of hypereutectic silicon aluminum alloy is above 12%, mainly in the range of 15% to 20%.

(4) Those with a silicon content of more than 22% are called high-silicon aluminum alloys, of which 25%-70% are the main ones, and the international silicon content can reach up to 80%.

Application of silicon aluminum alloy Si-Al powder

1) High-power integrated circuit packaging: high-silicon aluminum alloy provides effective heat dissipation;

2) Carrier: It can be used as a local heat sink to make the components more closely arranged;

3) Optical frame: high silicon aluminum alloy provides low thermal expansion coefficient, high rigidity and machinability;

4) Heat dissipation part: High silicon aluminum alloy provides effective heat dissipation and structural support.
