Galvanized
Galvanizing is a surface‑treatment process in which a layer of zinc is applied to the surface of metals, alloys, or other materials to enhance appearance and provide corrosion resistance.
Characteristics of galvanizing:
1. The surface is smooth, free of zinc nodules and burrs, and has a silvery-white appearance.
2. The thickness is fully controllable and can be selected arbitrarily within the range of 5–107 μm.
3. No hydrogen embrittlement and no thermal damage, ensuring that the material’s mechanical properties remain unchanged;
4. It can replace certain processes that require hot-dip galvanizing.
5. Excellent corrosion resistance, with a neutral salt spray test duration of 240 hours.
6. The zinc coating is relatively thick, with a fine, uniform grain structure and no porosity, exhibiting excellent corrosion resistance.
Scope of application:
Mechanical manufacturing, electronics, precision instruments, chemical engineering, transportation, aerospace, and more; it can also be used for the machining and processing of components such as steel nails, iron nails, fasteners, water pipe fittings, scaffolding couplers, wire rope thimbles, and other workpieces.
