Product description

Silicon metal 97 (Off-grade Silicon or Metallurgical Grade Silicon) is a category of silicon metal with a nominal silicon content of 97% (typically ranging from 97% to 98%), alongside impurities such as iron (Fe), aluminum (Al), and calcium (Ca).
Physical Form: Dark gray crystalline lumps, crushable into powders for alloy manufacturing.

Product Application
1. Aluminum Alloys: Enhances strength and corrosion resistance in cast alloys (e.g., ADC12).
2. Steelmaking: Used in ferrosilicon production for deoxidation and alloy modification.
3. Chemical Raw Material: Feedstock for synthesizing silicones (e.g., silicone rubber, oils), though further purification is often required.
4. Refractory Materials: Powdered form reinforces refractory castables for high-temperature stability
Product packing
Packing: 1 ton big bag, 20-25ton in a containter.
