Zinc alloy is a highly machinable engineering material valued for its dimensional stability, excellent surface finish, and cost efficiency. In CNC machining, it allows higher cutting speeds, reduced tool wear, and consistent repeatability—making it an ideal choice for precision components with complex geometry.
At Dewintech, zinc alloy is commonly used for functional housings, connectors, brackets, and appearance-critical parts, where accuracy and surface quality matter more than extreme strength.
Outstanding Machinability
Low cutting resistance enables fast cycle times and stable machining, ideal for medium- to high-volume CNC production.
High Dimensional Stability
Minimal internal stress and deformation ensure reliable tolerances, even for thin-wall or detailed features.
Excellent Surface Finish
Naturally smooth machined surfaces, well-suited for plating, painting, and powder coating.
Cost-Effective Precision
Compared with aluminum or steel, zinc alloy delivers precise results at lower overall manufacturing cost.
