钎焊 - 钎焊 - 分类和技术交付条件

[中文适用范围]： 本文件规定了用于钎焊金属的焊剂的分类，并根据其性能和用途描述了这些焊剂的特征，并给出了技术交付条件以及健康和安全预防措施。 本文档涵盖两类助焊剂：FH 和 FL。 FH级用于重金属（钢、不锈钢、铜及其合金、镍及其合金、贵金属、钼和钨）的钎焊。 FL 级用于铝及其合金的钎焊。 [外文原描述]： This document specifies the classification of fluxes used for brazing metals and characterizes these fluxes on the basis of their properties and use, and gives technical delivery conditions and health and safety precautions. This document covers two classes of flux, FH and FL. Class FH is used for the brazing of heavy metals (steels, stainless steels, copper and its alloys, nickel and its alloys, precious metals, molybdenum and tungsten). Class FL is used for the brazing of aluminium and its alloys.
