| L303 | Wire & rod | 660-725 | Ag45 Cu30 | Brazing of copper, copper alloys, steel and stainless steel etc. | BAg-5 | |
| L303F | Flux coated rod | 660-725 | Ag45 Cu30 | L303 coated with flux, the same application as L303. | BAg-5 | |
| L304 | Foil | 690-775 | Ag50 Cu34 | Brazing of copper, copper alloys and steel etc. | BAg-6 | |
| L308 | Wire & rod | 779-780 | Ag72 Cu Rem. | Brazing of copper and nickel under vacuum or reducing protective atmosphere. | BAg-8 | |
| L312 | Wire & rod | 595-605 |
| Brazing of copper, copper alloys, steel and stainless steel etc. | 焊接碳鋼及低合金鋼的焊芯， 一般都選用低碳鋼作為焊芯，并添加錳、硅、鉻、鎳等成分(詳見焊絲國家標準GB1300一77)。采用低碳的原因一方面是含碳量低時鋼絲塑性好，焊絲拉拔比較容易，另一方面可降低還原性氣體CO含量，減少飛濺或氣孔，并可增高焊縫金屬凝固時的溫度，對仰焊有利。加入其他合金元素主要為保證焊縫的綜合機械性能，同時對焊接工藝性能及去除雜質，也有一定作用。 | |
