About This Item
ASTM B579 is the ASTM standard that defines the Standard Specification for Electrodeposited Coatings of Tin-Lead Alloy (Solder Plate). It provides a focused technical reference for a solderable metallic coating used on parts where a tin-lead finish is needed. For buyers, engineers, and quality teams, this specification helps support consistent coating expectations, supplier communication, and product evaluation when solder plate performance and finish control matter.
What is ASTM B579?
ASTM B579 is a specification centered on electrodeposited tin-lead alloy coatings, commonly referred to as solder plate. As an ASTM standard, it serves as a formal reference for the coating type, its intended use, and the requirements that may apply to finished parts. It is especially relevant when a controlled solderable surface is needed and when coating quality must be defined in a clear, repeatable way for procurement, inspection, or acceptance purposes.
Where is ASTM B579 used?
This standard is commonly used in manufacturing and supply chains that rely on tin-lead solderable finishes on metal parts. It may apply to components, assemblies, or hardware that require electrodeposited solder plate for subsequent joining, assembly, or electrical connection needs. ASTM B579 is also useful in technical purchasing and quality control workflows, where the coating specification must be identified clearly before parts are produced, tested, or accepted.
Why is ASTM B579 important?
ASTM B579 matters because it helps establish a shared technical basis for coating performance and product consistency. Using the standard can reduce ambiguity in contracts, inspections, and supplier requirements by tying expectations to a recognized ASTM specification. For organizations that evaluate plated parts, it supports more reliable comparison between sources, clearer compliance checks, and better control over finish-related risk during manufacturing and assembly.
