Wako AZ Galva Leo (photo), a highly corrosion-resistant hot-dip zinc-aluminum alloy coating produced by Wako Metal Industry Co. in Suminoe Ward, Osaka City, is expanding its lineup. Because it boasts 10 times higher corrosion resistance than hot-dip galvanizing, it has been used mostly for measures against salt damage, but it has begun to be used for ordinary infrastructure applications such as bridges and overhead wires. The process contains 5% aluminum and 1% magnesium, and the company uses it for plating small items such as bolts and washers. The company says it is receiving an increasing number of inquiries from customers who want to extend the service life of their products, since rust from these fastening materials can easily damage them.
