High Performance Zinc-Magnesium Coating Available for Auto Panels Multinational steelmaker Tata Steel has expanded its range of its proprietary MagiZinc hot-dip galvanized zinc-magnesium coatings that promise higher corrosion protection and improved press shop performance.
The innovative products’ benefits--including allowing for the use of thinner coatings while maintaining the coatings’ corrosion and stone chipping performance--make them attractive for application in complex shaped automotive outer panels, including hoods, doors, body sides, bumpers and tailgates, especially where they will be used in corrosive environments.
Tata’s MagiZinc Auto with a Full Finish variant is said to have 25% lower zinc abrasion, and reduced zinc adhesion in the tooling process, a factor that may extend press-operating time by 30%. The product also offers enhanced corrosion protection twice that of conventional zinc coatings.
Tata Steel is also working on combining MagiZinc with Serica, its optimized steel surface technology, claiming it enables vehicle manufacturers to improve the paint appearance of their outer panels and lower their costs. Serica features a guaranteed low waviness of less than 0.40µm at 5% strain after forming and was developed to achieve an outstanding paint appearance for automobile outer panels.
