< WHY YOUR SCULPTURE CAST IS PROBABLY NOT A BRONZE
PRODUCTION METALS & ALLOYS
The alloys described in the following pages are grouped under the heading of their principal parent metal. Where stated, specific alloy grades are denoted by their common name(s) and/or standard BS/ISO/ASTM (UK/International/US) designations. Note: many of the familiar BS designations are subject to change as they become integrated with wider European standards.
Casting alloys are normally supplied to the founder in ingot or in billet form. Wrought grades are available as plates, sheets and a variety of cross sectional shapes, though the range and sizes of sections available can be widely variable for each alloy.
Sculptures cast and finished in the art foundry are nearly always supplied to the artist in an AS CAST metallurgical condition (not to be confused with the ‘as cast’ surface condition). This term indicates that the sculpture or other cast item is finished without undergoing annealing or any other structural treatment after casting. Some of the alloys listed in these pages, especially those in the aluminium group, may occasionally require some form of heat treatment after casting or welding. This can especially be the case if the structural strength of the finished cast is of particular issue, though it should be stressed that few such affected materials are ever specified for use in the art foundry.
