As a high-performance metal abrasive and functional material made of high-purity zinc, Zinc Shot is widely used in global anti-corrosion, metallurgy, chemical and new energy industries due to its excellent corrosion resistance, moderate hardness and good chemical reactivity. Driven by the global demand for industrial anti-corrosion upgrading, the rapid development of infrastructure construction and the expansion of new energy storage fields, the market demand for Zinc Shot has maintained a steady growth trend. Based on the latest global zinc industry research reports, technical documents and process standards, this document systematically elaborates on Zinc Shot from six core dimensions, including product overview, core characteristics & technical parameters, advanced manufacturing process, global quality standards & certifications, diversified application scenarios, and global market adaptation & service support, to fully present its core value in the industrial chain.

1. Product Overview: Zinc Shot

According to professional definitions from the global metal processing and abrasive industry, Zinc Shot refers to spherical or granular products made of high-purity zinc through precision forming, heat treatment and multi-stage screening processes. It is also known as zinc granules or spherical zinc powder, and its core component is zinc with different purity grades to meet diverse application needs—including 0# zinc (Zn content ≥99.995%), 1# zinc (Zn content ≥99.99%) and 2# zinc (Zn content ≥99.95%). The core specification range covers a particle size of 0.2mm-3.0mm, which can be divided into three categories according to application scenarios: micro-particle size (0.2-0.8mm) for chemical reaction and precision anti-corrosion, medium particle size (0.9-1.8mm) for general surface treatment, and large particle size (1.9-3.0mm) for heavy-duty shot peening. Different from traditional irregular zinc powder, Zinc Shot has the characteristics of uniform particle shape, high sphericity and stable physical properties, which can ensure consistent effect in batch application and reduce material waste.

2.Core Characteristics & Technical Parameter Advantages

The core competitiveness of Zinc Shot lies in its excellent comprehensive performance derived from high-purity zinc materials and refined processing. Based on industrial test data , its key characteristics and technical parameters are as follows: First, superior corrosion resistance—zinc can form a dense zinc oxide or basic zinc carbonate film on the surface in the natural environment, effectively isolating the internal material from the corrosive medium, and is the core material for anti-corrosion treatment. Second, moderate hardness & low damage—with a hardness of HBW 70-90, it can achieve surface cleaning and strengthening without damaging the substrate of soft metal workpieces, and the breaking rate is ≤3% after 500 cycles of use. Third, good chemical reactivity—high-purity Zinc Shot can undergo stable chemical reactions with acids, alkalis and other substances, making it suitable for chemical synthesis, hydrogen production and other fields. Fourth, precise physical parameters—adopting advanced forming technology, the sphericity rate can reach ≥95%, the particle size tolerance is ≤±0.05mm, and the bulk density is 4.2-4.5g/cm³, ensuring uniform force transmission and material distribution. Fifth, cost-effectiveness—compared with precious metal anti-corrosion materials, zinc has obvious cost advantages, which can reduce the comprehensive anti-corrosion cost of enterprises by 40%-60%.

3. Advanced Manufacturing Process & Raw Material Advantages

The stable performance of Zinc Shot is fundamentally guaranteed by its advanced manufacturing process and high-quality raw materials. As W. Edwards Deming, the American quality management guru, put it, “Quality comes not from inspection, but from improvement of the production process”. This philosophy is fully implemented in our production. We select high-purity electrolytic zinc ingots (Zn content ≥99.995% for 0# zinc) as raw materials, which are sourced from well-known zinc mills adopting world-leading closed blast furnace smelting or electrolysis technology, ensuring stable chemical composition and low impurity content (lead ≤5mg/kg, iron ≤10mg/kg for 0# zinc). The manufacturing process integrates five core links: first, precision forming—adopting gas atomization or centrifugal atomization technology, melting zinc ingots into liquid state and atomizing into spherical droplets, which are rapidly solidified into zinc shot; second, heat treatment—annealing at 200-300℃ to eliminate internal stress and adjust hardness; third, surface purification—removing oxide layers through pickling and drying treatment to enhance corrosion resistance and reactivity; fourth, multi-stage screening—using ultrasonic screening equipment to accurately control particle size distribution, ensuring that the qualified rate of particle size meets ≥98%; fifth, sealed packaging—adopting moisture-proof and anti-oxidation packaging to avoid surface oxidation during transportation and storage. This refined process system ensures consistent quality of each batch of products.

4. Compliance with Global Quality Standards & Certifications

To adapt to the high-end requirements of global markets, our Zinc Shot fully complies with major international and industry standards retrieved from Google professional standard databases. It strictly implements the Chinese national standard GB/T 470-97 (Zinc ingots) for raw material quality control, and meets the Japanese industrial standard JIS H2107 (Zinc ingots) and JIS H1111 (Chemical analysis methods for zinc) for component analysis and testing. For anti-corrosion and chemical application fields, it also complies with the relevant requirements of global anti-corrosion material safety standards. Kaoru Ishikawa, the Japanese quality management expert, emphasized, “Quality management is the work of all employees and all departments. If all employees and all departments work together, they will surely succeed”. In line with this concept, we have obtained ISO 9001 quality management system certification and CE certification for European market access. A full-process quality inspection mechanism is implemented, covering chemical composition analysis (atomic absorption method, spectrophotometry), particle size detection, hardness testing and sphericity verification, with traceable test reports provided to customers to ensure product reliability.

5. Diversified Application Scenarios Across Industries

Global industry data and application cases show that Zinc Shot has a wide range of applications in multiple industrial fields. First, in the anti-corrosion industry—it is used for thermal spraying anti-corrosion of steel structures (bridges, pipelines, marine equipment), and as a raw material for zinc-rich anti-corrosion coatings, forming a protective zinc layer on the surface of workpieces to extend service life ³. Second, in the chemical industry—it is used for chemical synthesis reactions (such as production of zinc salts) and laboratory hydrogen production, relying on good chemical reactivity to ensure reaction efficiency and product purity. Third, in the new energy storage industry—it is applied to the manufacturing of zinc-based flow battery electrodes and energy storage materials, with the advantages of low cost and high safety, and has broad application
