Product mechanism:
Flake zinc-aluminum alloy powder combines the characteristics of flake zinc powder and flake aluminum powder, achieving a balance in material preparation, corrosion resistance and coating appearance. Zinc-aluminum alloy has good ductility
The scale specifications are easy to control and a high specific surface area of scales can be easily obtained: Flake zinc-aluminum alloy powder has the effective anodic protection of pure Zn layer on the steel substrate, and because it contains enough Al, it can form a complete Al2O3 protective film to improve its corrosion resistance. Due to the infiltration of aluminum, the flake zinc-aluminum alloy coating also has excellent metallic luster that pure zinc powder does not have. At the same time, zinc-aluminum alloy powder also avoids the problem of uneven coating liquid caused by different densities of zinc powder and aluminum powder in the coating, and is an ideal anti-corrosion pigment for chromium-free Dacromet coating.
Product use:
Mainly used in GMT and Dacromet coating technology. Widely used in surface treatment of organic and water-based coatings, ships, cars, high-speed railways, power facilities, steel buildings, etc.

Application areas
Zincizing Material
Mainly used for steel structure
Brazing
ZnAl5 (melting point 382℃) is a zinc-based eutectic filler metal suitable for brazing pure zinc and zinc alloys. ZnAl15 (425-460℃ solid-liquid phase) is used as a universal brazing filler metal for aluminum-aluminum brazing and aluminum-copper brazing with excellent spreading and mechanical properties
Zinc-Aluminium Coating
Anti-corrosion property on the surface of steel, such as railway systems, steel structure bridges, automobile manufacturing, ships, ports, docks, etc.
