REFLECTOR SHEET

A temperature, usually just higher than the transformation range, employed in the heat treatment of steel to refine the structure – in particular, the grain size. An alclad product containing on one side a surface layer of high-purity aluminum superimposed on a core or base alloy of commercial-purity aluminum or an aluminum – manganese alloy. The high-purity coating imparts good polishing characteristics and the core gives adequate strength and formability.
