Aluminum Silicon Carbide Al/SiC

Description of Aluminum Silicon Carbide Powder：

Silicon carbide aluminum is a compound composed of silicon carbide (SiC) and aluminum (Al), also known as silicon carbide aluminum alloy. This material has some unique properties that make it of great value in many applications.

High hardness: The hardness of silicon carbide aluminum alloy is higher than that of traditional aluminum alloy, with excellent wear resistance and corrosion resistance. This makes it excellent in applications that require high strength and durability, such as the aerospace, automotive, and electronics industries.

Low density: The density of silicon carbide aluminum is relatively low, about 2.7 grams/cubic centimeter. This makes it a lightweight, high-strength material suitable for applications that require weight reduction, such as aerospace and electric vehicles.

High-temperature resistance: Aluminum silicon carbide has excellent high-temperature resistance and can maintain stable physical and mechanical properties at high temperatures. This makes it ideal for applications that operate in high-temperature environments, such as aero-engine components and high-temperature stoves.

Good electrical conductivity: aluminum silicon carbide can be used to manufacture electronic components and conductor materials because of its good electrical conductivity.

Good processing performance: aluminum silicon carbide can be cut, drilling, milling, and other processing operations, and processing performance is good. In addition, it can also be processed by casting, forging, rolling, and other processes.

Environmental protection: Aluminum silicon carbide in the manufacturing and processing process will not produce harmful substances and is an environmentally friendly material.

Production Method of Aluminum Silicon Carbide Powder：

Fusion method

The melting method is a method to prepare silicon carbide aluminum, and the method is to mix aluminum and silicon carbide according to a certain proportion, melt at high temperature, and then cool and solidify to obtain silicon carbide aluminum ingot. The specific steps are as follows:

The silicon carbide powder and aluminum powder are mixed according to a certain proportion.

The mixed powder is put into a crucible and sent to a high-temperature furnace for melting.

It is kept at a high temperature for some time so that aluminum and silicon carbide are fully melted.

Slowly cooled and solidified to obtain aluminum silicon carbide ingots.

The advantages of the melting method are a simple process and convenient operation, which can prepare large-size silicon carbide aluminum ingots. However, the melting method also has some shortcomings. Defects such as oxidation inclusion are easy to occur in the high-temperature melting process.

Second, chemical vapor deposition method

Chemical vapor deposition (CVD) is a method to prepare silicon carbide aluminum, which is a chemical reaction of compounds containing silicon carbide and aluminum to produce silicon carbide aluminum thin film under certain conditions. The specific steps are as follows:

The appropriate compound is selected as the raw material.

At a certain temperature and pressure, the compound vapor is deposited on the surface of the substrate.

A chemical reaction occurs to form a thin film of aluminum silicon carbide.

The advantage of chemical vapor deposition is that high-purity and high-performance silicon carbide aluminum film can be prepared. However, the chemical vapor deposition method also has some disadvantages, such as the need to use high temperature and high vacuum equipment, the preparation process is more complicated, and the cost is higher.
