Weldynasty HS201 Purple Copper Welding Wire – High-Strength, Multi-Process Copper Welding
HS201 is a commonly used purple copper welding wire compliant with GB/T 9460-2008 (model SCu1898, equivalent to AWS ERCu). With a primary copper content of ≥98.0% plus small amounts of tin, silicon, manganese, and phosphorus, it delivers excellent welding process performance, smooth bead formation, high mechanical properties, and good crack resistance.
Key Features
High-Purity Copper – ≥98.0% copper content for reliable conductivity and weld quality.
Deoxidized Composition – Silicon, manganese, and phosphorus act as deoxidizers, while tin improves copper flowability.
Excellent Weldability – Smooth, aesthetically pleasing bead, high mechanical properties, and good crack resistance.
Multi-Process Compatibility – Suitable for oxy-acetylene welding, shielded metal arc welding, TIG, and MIG welding.

Operating Notes
Select spooled or straight-bar form based on your welding method and joint access.
For oxy-acetylene welding, use in conjunction with CJ301 flux.
Clean the workpiece before welding to remove oil, oxide, and contaminants.
Adjust current and technique to the material thickness and welding process used.
Wear appropriate PPE and ensure good ventilation.
Ideal For
Welding of copper components, including steel ingot continuous casting crystallizers, steel mill electrode clamps, conductive rolls, conductive plates, heating elements, copper containers, and copper sculptures.
