How to Choose the Right Zinc Wire for Thermal Spray Applications?
Selecting the correct zinc wire for thermal spray is mainly about matching purity, diameter, and process stability with your coating system. If the wire specification does not align with the spray equipment and coating requirement, you will face unstable arc, uneven coating, and higher material loss.
The right choice improves deposition efficiency, coating adhesion, and long-term corrosion protection performance.

What Factors Should You Consider When Choosing Zinc Wire?
Why Does Purity Matter in Thermal Spraying?
Higher purity zinc wire ensures:
-
stable arc behavior during spraying
-
reduced oxidation and slag formation
-
smoother coating surface
99.95%–99.995% is preferred for high-performance corrosion protection systems.
How Does Wire Diameter Affect Spray Performance?
Wire diameter directly impacts:
-
feed stability in spray gun
-
melting rate consistency
-
coating thickness control
1.6 mm is widely used for precision work, while 2.0 mm is preferred for industrial high-output spraying.
Why Is Compatibility With Equipment Important?
Different spray systems require different wire feeding characteristics. Incorrect size or hardness can cause:
-
wire jamming
-
unstable arc
-
uneven coating distribution
