Data Display
People process visual data differently, so we have tried to accommodate this. Choose the style in which you want the data displayed using either of the two options in the expansion list below.
Please take note that in the data presented below:
- the footnotes. at the bottom of the page, listed alphabetically, contain important information.
- '*' indicates - this alloy has been registered with the U.S. EPA as Antimicrobial.
- '~' indicates - this is a nearest equivalent alloy match and there are differences in the composition of which to be aware.
- '#' indicates - Lead Free - designed to maintain the mechanical properties of the Lead (Pb) containing original, but now safe and free of Lead (Pb).
- 'GC' is short for Continuous Casting
- 'GZ' is short for Centrifugal Casting
- 'Rem' stands for Remainder, a synonym for Balance
- Values are given as maximum percentages, unless shown as a range or explicitly stated as minimum
- '%' refers to % by mass
