Silicon metal

Silicon metal, also known as industrial silicon or crystalline silicon. Dark gray luster. It has a high melting point and good heat resistance. It has high resistivity and high anti-oxidation effect. Usually, the metal silicon has a particle size of 10 to 100 mm or 2 to 25 mm.

The main raw material of metal silicon is silica, petroleum coke, wood chips and the like. It is then smelted in an electric furnace. There are metal silicon blocks and silicon metal powder. The country with the largest production of metal silicon in the world is China.

The main use of metal silicon is to add aluminum ingots. This aluminum ingot is not an electrolytic aluminum ingot. It is an alloy aluminum ingot. This aluminum ingot is mainly used for automobile wheels and aluminum products. Because a certain amount of metal silicon is added to the aluminum water, the hardness and strength of the aluminum can be increased.

Mainly according to the level of trace elements to distinguish the level. Different products are required by customers.

The main grades are the following, ranging from low grades:

Grade	Composition
1501	Si 99.69%,Fe0.15%,Al 0.15%,Ca 0.01%,P≤0.004%
1502	Si 99.68%,Fe0.15%,Al 0.15%,Ca 0.02%,P≤0.004%

For consumers, when buying metal silicon, they hope to buy quality. As a metal silicon manufacturer, quality is the life of an enterprise. If the quality is excellent, then you will get more attention from customers. The development of enterprises will get better and better.

Therefore, both consumers and manufacturers are very concerned about the quality of metal silicon. How to judge whether the metal silicon purchased by you is in compliance with the standard? Third party testing is possible. Such as SGS/BV. The content of each element can be seen in the report presented by the third-party testing agency. Thereby determining whether the purchased product meets its own needs.
