BS-1400 (old) - Equivalents
This is a list of the British Standard's Cast Copper Alloys, and their equivalent or nearest equivalent in the EN, DIN and UNS standards
Filtering
If you cannot find what your are looking for, you can call and ask or use the search tool below.
Many of our Engish speaking customers still use the old BS 1400 designations on a day to day basis. This tool is there to make sure when others have the BS 1400 designation dropped on them, that they can look up their equivalents or nearest equivalents, if any, a little more easily.
The Old BS 1400 designation system has a perculiar grouping which was as follows:.
- Group A - Alloys in common use - PB4, LPB1, LB@, LB4, LG1, LG2, SCB1, SCB3, SCB6, DCB1, DCB3, PCB1
- Group B - Special purpose alloys - HCC1, CC1-TF, PB1, PB2, CT1, LG4, AB1, AB2, CMA1, HTB1, HTB3
- Group C - Alloys in limited production - LB1, G1, G3, G3-TF, LB5, SCB4, CT2, AB3, CN1, CN2
Instead we have grouped these by families, as the filters provided below will illustrate.

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
