Zinc Shot

As a specialized supplier of abrasives and surface preparation technologies, Alfa Chemistry offers high-quality zinc shot tailored for use in metal surface treatment and finishing. Manufactured through a refined process involving wire drawing, precise cutting, and mechanical rounding, zinc shot is particularly effective for deburring, cleaning, and whitening of aluminum and zinc alloy die castings. Its unique balance of physical and chemical properties enables efficient surface finishing without damaging sensitive substrates, making it a superior alternative to harder or more reactive abrasives.

Key Features

• High Purity Zinc: It provides excellent surface results and minimizes contamination during blasting.
• Optimal Specific Gravity: With a density close to steel, it ensures effective impact energy while maintaining control on softer materials.
• Soft Abrasive Action: It offers superior deburring and cleaning performance without causing erosion or deformation to delicate surfaces.
• Anti-Corrosion Effect: Zinc particles form a micro-coating on treated surfaces, enhancing corrosion resistance post-treatment.
• Safety Advantage: Compared to aluminum-based abrasives, zinc shot has a much higher ignition threshold, significantly reducing dust-related fire hazards.
• Surface Brightening: It leaves a clean, noticeably whiter finish on treated workpieces.

Available Grades and Applications

To cater to diverse application needs, we offer zinc shot in distinct grades:

General Hardness Zinc Shot (HG-AB145)

It is ideal for general deburring, cleaning, and surface finishing applications where a balance of effective abrasive action and gentle surface treatment is required. It is particularly well-suited for:

• Deburring and deflashing of aluminum and zinc die castings.
• Surface cleaning of various light metal castings.
• Achieving a bright and consistent surface finish on non-ferrous components.

High Hardness Zinc Shot (HG-AB146)

It provides a slightly more aggressive cleaning and deburring action while still retaining the core benefits of zinc shot. It is recommended for applications where a more robust abrasive effect is desired, such as:

• Removal of stubborn burrs or thicker flash on aluminum and zinc die castings.
• Preparation of surfaces for subsequent coatings or treatments.
