FeSi Al50 lump

Ferrosilicon aluminum is an important kind of industrial alloy, which is widely used in aviation, transportation, construction, automobile and other important industries. It is also used to manufacture low-medium strength castings with complex shapes, such as cover plate, electric machine shell, bracket, etc., and also used as brazing solder.The alloy is a typical eutectic alloy with simple phase diagram and no intermediate compounds.It has the advantages of good casting performance, high strength and low price.Aluminum is the third major group of elements, while silicon is a semiconductor element.

When silicon content is low (such as 0.7), al - si alloys are more malleable and are often used as deformation alloys.When silicon content is high (e.g., 7%), aluminum - silicon alloy melt fills better, often used as casting alloy.When the silicon content exceeds that of al-si eutectic point (the silicon content is 12.6%) and the grain content of silicon is as high as 14.5% ~ 25%, a certain amount of Ni, CU, Mg and other elements can be added to improve its comprehensive mechanical properties.They can be used in automobile engines to replace cast iron cylinders for significant weight reduction.The aluminum silicon alloy used as cylinder can be electrochemically treated with etching the surface aluminum and retaining the primary silicon particle embedded in the cylinder inner wall.The alloy containing 11% ~ 13% silicon is one of the best piston materials for its light weight, low expansion coefficient and high corrosion
