This document specifies designations for filler materials for brazing on the basis of their chemical composition. The designation includes their solidus/liquidus temperatures. This document applies to the metallic part of filler materials used in brazing products, for example foils, wires, rods, pastes, flux-coated rods or wires and flux-cored rods or wires.
Abstract
Overview
EN ISO 3677:2024 - Filler metal for brazing: Designation (ISO 3677:2024) defines a standardized system for naming filler metals for brazing based on their chemical composition and solidus/liquidus temperatures. Published by CEN and identical to ISO 3677:2024, this fourth edition supersedes EN ISO 3677:2016 and applies to the metallic part of brazing products (foils, wires, rods, pastes, flux‑coated or flux‑cored rods/wires).
Keywords: EN ISO 3677:2024, filler metal for brazing, designation, solidus liquidus, brazing alloys, chemical composition, brazing filler materials.
Key topics and requirements
- Three-part designation: The standard prescribes a designation format of three parts separated by dashes.
- First part: the letter B (for brazing).
- Second part: symbols indicating constituent metals/metalloids and their nominal mass percentages:
- Major element first with its nominal percentage (whole number, ±1 accuracy).
- Other constituents follow in decreasing nominal percentage; if equal, order by decreasing atomic number.
- When a range is specified, use the mean (rounded to nearest whole number, or nearest even if halfway).
- Elements with nominal values
