PREFACE

Visual Quality Characteristics of Aluminum Sheet and Plate has been compiled by the Technology Committee of the Sheet and Plate Division as a reference for those who have an interest in these rolled products and who may have a need to know the terminology commonly used in this largest segment of the aluminum industry.

The terms are arranged alphabetically in the index based on the term noun followed by the appropriate adjective. There is a second index which categorizes the terms by the characteristics of flatness, metallurgical, surface, other and coating. The preferred terms, obtained by consensus, are defined; other terms for the same condition are cross-referenced in the alphabetical index.

The reader should be mindful that terminology is the subject of this document. The visual quality characteristics defined, together with any visual representation, do not constitute quality standards. In many instances, the definitions are enhanced by providing visual extremes.

Wherever possible, typical causes are given for the visual characteristics. These causes may differ from the experience of the reader because of alternate equipment, processes or technology. This edition retains the use of inch as the unit of distance referenced on figures whenever it was available from original sources.

Though a number of Association member companies provided pictures and sketches, Kaiser Aluminum and Chemical Corporation and the Japan Light Metal Association also gave The Aluminum Association use of illustrations from their published documents as information sources.

The 2002 Fourth Edition has been updated based upon suggestions made by Arvid N. Anderson, consultant. Mr. Anderson is the former chairman of The Aluminum Association's Task Group on Visual Quality Attributes of Aluminum Sheet and Plate.
