Abstract

See full text

An Al—Zn—Si—Mg alloy coated strip that has Mg2Si phase particles that are ≤2 μm and have a globular shape. A method of forming an Al—Zn—Si—Mg alloy coated strip comprises (a) heat treating a solidified coating to facilitate globularisation of Mg2Si phase particles in the coating and/or (b) changing the coating bath chemistry to form intermetallic compound phases that act as nucleation sites for Mg2Si phase particles with the result that small Mg2Si particles form on solidification of the coating.
