Historical Standard: Standard Guide for Preparation of Zinc Alloy Die Castings for Electroplating and Conversion Coatings<\/h4>\n
\n

ASTM B252<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This guide is intended as an aid in establishing and maintaining a procedure for preparing zinc alloy die castings for electroplating and conversion coatings. It is primarily intended for the preparation of Alloys UNS Z33521 (AG-40A) and UNS Z35530 (AC-41A) (Specification B86) for electroplating with copper, nickel, and chromium (Specification B456).<\/p>\n

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n
