High Purity Zinc Pellets

Zinc shot is a blasting material used for metal surface treatment, primarily made from high-purity zinc, and widely applied in industrial fields such as deburring, polishing, and surface strengthening. Below is a comprehensive overview of its product introduction:

Basic Parameters and Specifications  
Size Range: Diameter typically ranges from Φ0.4mm to Φ4.0mm, with some manufacturers offering more detailed specifications (e.g., 0.5mm, 0.8mm, 1.2mm, etc.), and support for custom special sizes.  
Shape: Initial form is mostly cylindrical cut wire, which may become spherical after use to improve surface treatment effectiveness.  
- Packaging: Commonly packaged in 25kg/bags, with some offering ton-level wooden box packaging (e.g., 40 bags/ton).  
Chemical Composition and Physical Properties 
Purity: Zinc content ≥99.99% (complying with national standard GB/T 470-2008), with extremely low impurity levels such as iron (Fe≤0.0018%) and aluminum (Al≤0.003%).  
Hardness: Various manufacturers provide multiple hardness ranges, such as HV35-80, HV40-50, HV30-45, etc., suitable for different surface treatment needs of workpieces.  
Specific Gravity: Approximately 7.1g/cm³, with high density, making it suitable for efficient deburring.  
Application Fields  
Surface Treatment: Used for descaling, deburring, and surface finishing and brightening of aluminum alloys, zinc alloys, copper parts, stainless steel castings, etc., to enhance fatigue and corrosion resistance.  
Electroplating Industry: Surface strengthening and finishing of electroplated steel plates and small components.  
Special Scenarios: Replaces iron-containing blasting materials to avoid contamination of non-ferrous metal surfaces by iron impurities.  
Product Features  
Eco-friendly and Efficient: Does not damage the workpiece surface during processing, earning it the title "beautician of metal surfaces."  
- Safety: Compared to aluminum shot, zinc shot poses no risk of explosion or combustion during blasting, ensuring safer operation.  
- Diverse Options: Customizable in different hardness levels, sizes, and shapes to meet various industrial needs.  

### 5. **Production Standards and Processes**  
- Utilizes advanced processes such as electronic spiral cutting and passivation forming to ensure uniform particles and defect-free surfaces.  
- Raw materials are strictly screened, with a bright and contamination-free appearance, complying with high-precision industrial standards.
