Silicon Metal for Aluminum
Silicon metal is very widely used in aluminum products. Aluminum alloys, silicon aluminum alloys, and aluminum silicon welding rods all use silicon metal as an important raw material. The use of silicon metal significantly improves the strength, hardness, wear resistance, and corrosion resistance of aluminum products and, due to its low cost, reduces the consumption of other raw materials. Therefore, it is efficient in reducing costs and has been adopted by many aluminum product manufacturers.
Grades of Silicon Metal for Aluminum
The main grade of silicon metal for aluminum are 553#, 441#, 3303#, and 2202#. The silicon content varies with the grade of silicon metal, so the appropriate grade should be selected based on the performance requirements and application of the aluminum to be produced. For general aluminum products, 553# or 441# silicon metal is used, which is less expensive, economical, and provides sufficient strength and corrosion resistance. On the other hand, aerospace aluminum products require high-purity silicon metal, and high-purity silicon metals such as 3303#, 2202#, and 1101# are chosen.
Index of Silicon Metal for Aluminum
XLS Metals mainly supplies 441#, 553#, 3303#, 2201#, and 1101# silicon metal to aluminum mills. Grades are usually classified based on the component indicators of iron, aluminum, and calcium in silicon metal. For example, 441# silicon metal contains 0.4% iron, 0.4% aluminum, and 0.1% silicon. A detailed index table is provided so that users can easily identify the different silicon metal for aluminum indexes.
Requirements for Silicon Metal for Aluminum
Silicon metal for aluminum is usually required to be of high purity and to have a silicon content of at least 99%. This ensures the quality of the aluminum product. In addition to trace elements of iron, aluminum, and calcium, iron and phosphorus content is kept low. Typically, iron should be less than 0.5% and phosphorus less than 0.02%. In addition to chemical indices, there are also requirements for grain size and physical performance, with grain size typically controlled to within 5 cm. Silicon metal grains with smaller grain size are more evenly distributed in the aluminum alloy, which improves the mechanical performance of the aluminum. High purity silicon metal powders are widely used in the production of aluminum for aerospace applications. The physical performance requires high hardness and good thermal stability and can be adapted to different aluminum product manufacturing processes.
In which aluminum is silicon metal used?
Among aluminum products, silicon metal is widely used in the production of 4000 series aluminum alloys. These aluminum alloys are used in the manufacture of automotive parts, aerospace parts, and household appliances. Silicon aluminum alloys are also widely used in the manufacturing process of engine pistons, cylinders, and cylinder heads and have high temperature resistance and good wear resistance.
Welded aluminum alloys require excellent corrosion resistance and mechanical strength, and metallic sillicon helps to improve their performance. In the manufacturing process of die-cast aluminum alloys, metallic silicon improves the fluidity and wear resistance of the alloys and is widely used in the outer shells of automobiles, motorcycles, and electronic products.
