Casting Alloys

Alcoa produces standards for many of the casting alloys registered by the Aluminum Association. Standards identified with the ‘SS’ prefix followed by the alloy designation denote the standard that most closely matches the nominal registered composition.  Standards identified with the ‘KA’ through ‘KH’ prefixes are range standards. These are typically used to bracket the composition range in the alloy of interest.
Alcoa produces ‘ST’ standards to provide a high end reference point for many of the typical minor elements. The ‘ST’ standards are used to demonstrate accurate analysis at or near the typical concentration limits for the minor elements.
With the broad range of casting alloys in use, suitable standards may not exist. To address this need, Alcoa can produce a specialty standard to meet your exact composition targets.  All of these standards are suitable for use in the preparation and periodic adjustment of analytical curves.
