What can metal silicon be used for?
Metal silicon is also called industrial silicon. It is mainly used as an additive for non-ferrous alloys. Silicon is a non-metallic element that is gray and non-ferrous. Metal silicon can be divided into many types according to its content. The more common ones are 553 metal silicon, 441 metal silicon, etc., which are mainly supplied by Shengkai Metallurgy. In addition, there are some other types, such as 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades. Of course, metal silicon not only has many types, but is also used in different fields. Next, we have to understand the different fields of metal silicon.
The use of metal silicon can be said to be There are many kinds of materials, which can be used to produce rubber and silicone resin. Silicone has very good elasticity and is also resistant to high temperatures. Silicone resin can also be used to produce insulating paint and high-temperature coatings.
In the process of steel smelting, adding metal silicon can improve the performance of steel. Silicon can also be used to configure alloys. For example, silicon-copper alloy has good welding performance and is not easy to produce sparks when impacted. It can be seen that the application of metal silicon is still very wide.
