Does anybody know what ZCMS 66 is?

Does anybody know what ZCMS 66 is?

Does anybody know what ZCMS 66 is?

(OP)
In a valve data sheet I found ZCMS 66 specified as seat and spring material. I didn't any International standard referring to it. Does anybody know if this is a specific manufacturer standard or what it is? Thanks.

RE: Does anybody know what ZCMS 66 is?

     I found that "ZCM" may stand for Zinc Composite or Zinc Containing Material; nothing meaningful for "ZCMS"... Is there the possibility of a mispelling, parhaps?

Zinc Material Safety CAS number 7440-66-6. I would believe they are stating the material coating is Zinc or has Zinc in it, and the safety date sheet Cas Number is 66, Making it ZCMS-66. If I remember right, 66 stand for Molecular weight for ZINC.
