ALLOY WIRE
PRODUCTS
ZnAl alloy wire (ZnAl2, ZnAl4, ZnAl15, ZnAl22) is used for applying zinc-aluminum coatings by spray metallization to protect various steel elements and structures against corrosion. The wire is also utilized in the electrotechnical industry. The wire is produced from SHG zinc of the highest purity, 99.995% Zn.
Applying zinc-aluminum coatings by spray metallization is a modern corrosion protection method. Compared to hot-dip galvanizing and electroplating of zinc-aluminum coatings, it offers the following advantages:
no dimensional limitations of the coated elements,
the possibility of metallizing structures directly on the construction site,
the ability to perform coating repairs on joints or areas with mechanical damage,
dużą odpornością na uszkodzenia mechaniczne,
high resistance to mechanical damage,
Spray metallization eliminates the risk of thermal deformation of the protected elements.
Zinc-aluminum coatings are applied using electric or flame spray guns. Depending on the type of spray gun used, ZnAl alloy wire with appropriately selected physical properties is recommended.
