Ferrosilicon zirconium is an important alloy material, mainly used to make heat-resistant and corrosion-resistant alloys. According to its composition and uses, ferrosilicon zirconium can be divided into the following categories:
1. High-silicon ferrozirconium: High-silicon ferrozirconium is a type of silicon alloy with a higher zirconium content. Generally, the zirconium content is more than 15%. It has good heat resistance and corrosion resistance and is mainly used to make high-temperature alloy materials, such as aerospace engine parts, spacecraft materials, etc.
2. Low silicon ferrozirconium: Low silicon ferrozirconium is a silicon ferrozirconium alloy with a low zirconium content. Generally, the zirconium content is less than 10%. It has high heat resistance and corrosion resistance and is mainly used to manufacture high-temperature alloy materials, stainless steel and acid-resistant alloys.
