COMPOSITE ALUMINUM TREAD PLATE SHEET

摘要

The invention relates to a tread plate product having an aluminum composite structure. The structure includes a core layer and at least one clad layer, wherein the core layer is an alloy of the AA5XXX series alloys in which the Mg content is 2% by weight or more and the clad layer(s) is made of an alloy of the AA3XXX series or AA5XXX series alloys, in which the Mg content is 1% by weight or less. The structure may be made in thin gauge while retaining or enhancing desirable mechanical properties.
