摘要： A metal sheet including a substrate having at least one face coated by a metallic coating is provided. The metallic coating has an aluminum content by weight tAl of between 3.6 and 3.8% a magnesium content by weight tMg of between 2.7 and 3.3%. The coating has a microstructure comprising a lamellar matrix of eutectic ternary Zn/Al/MgZn2 and possibly: dendrites of Zn with an accumulated surface content exceeding 5.0%, flowers of binary eutectic of Zn/MgZn2 with an accumulated surface content less than or equal to 15.0%, dendrites of binary eutectic Zn/Al surface with an accumulated surface content of less than 1.0% islets of MgZn2 with an accumulated surface content below 1.0%.
