Japan's largest galvanizing and processing capacity of zinc alloy plating


Zinc-iron alloy plating: Strontium zinc

Long-term corrosion protection performance

Strontium zinc Strontium zinc

Alloying 0.3 to 0.6 wt% of iron with the zinc suppresses excessive sacrificial corrosion losses of the zinc, and thus dramatically increases the time it is protected against corrosion. This enables 3 to 4 times higher corrosion resistance than is possible with ordinary zinc plating.

Glossy color tone

Alloying zinc with iron makes it easy to produce a black tone because the plating base becomes a brownish color.

By alloying different metals on a single metal, the crystal grains of the alloy plating become extremely fine and a color tone with a rich glossy finish is obtained.

Treatment is available in a white or black finish.
