| Silver 銀基 | L302 | Wire & rod | 745-775 | Ag25 Cu40 | Brazing of copper, copper alloys, steel and stainless steel etc. | 1)碳(C)碳是鋼中的主要合金元素，當含碳量增加時，鋼的強度、硬度明顯提高，而塑性降低。在焊接過程中，碳起到一定的脫氧作用，在電弧高溫作用下與氧發生化合作用，生成一氧化碳和二氧化碳氣體，將電弧區和熔池周圍空氣排除，防止空氣中的氧、氮有害氣體對熔池產生的不良影響，減少焊縫金屬中氧和氮的含量。若含碳量過高，還原作用劇烈，會引起較大的飛濺和氣孔。考慮到碳對鋼的淬硬性及其對裂紋敏感性增加的影響，低碳鋼焊芯的含碳量一般為0. 1%。 |
| 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 | |

| L312 | Wire & rod | 595-605 |
| Brazing of copper, copper alloys, steel and stainless steel etc. | 六、藥皮在焊接過程中起著極為重要的作用。若采用無藥皮的光焊條焊接，則在焊接過程中，空氣中的氧和氮會大量侵入熔化金屬，將金屬鐵和有益元素碳、硅、錳等氧化和氮化形成各種氧化物和氮化物，并殘留在焊縫中，造成焊縫夾渣或裂紋。而熔入熔池中的氣體可能使焊縫產生大量氣孔，這些因素都能使焊縫的機械性能（強度、沖擊值等）大大降低，同時使焊縫變脆。此外采用光焊條焊接，電弧很不穩定，飛濺嚴重，焊縫成形很差。 | |
