It is used for gas tungsten arc welding (GTAW/TIG) and gas metal arc welding (GMAW/MIG) of copper,copper-silicon and copper-zinc based alloy metals to themselves, and to plain and galvanized steel also. This alloy is extensivelyapplied in automobile industry. |
Aluminum Bronze | AWS 5.7/5.8:ERCuAl-A1 DIN1733：SG-CuAl8 BS2901：CC28 | An iron-free copper-aluminum based bronze that provides good resistance to seawater corrosion and the most commonly-used acids in various concentration and temperatures. It is normally used as a surfacing metal for wear-resistant metal surface where high corrosion resistance is required, for example in shipbuilding, chemical industry and automobile industry. |
Aluminum Bronze | AWS 5.7/5.8:ERCuAl-A2 DIN1733：SG-CuAl10Fe BS2901：C28 | An iron-bearing copper-aluminum bronze used for joining aluminum bronzes of similar composition ,manganese, silicon bronzes ,some copper-nickel alloys ,ferrous metals and dissimilar metals, for example aluminum bronze to steel and copper to steel. It is also used for welding parts such as ship propeller where wear-and corrosion-resistances are required. |
Aluminum Bronze | AWS 5.7/5.8:ERCuAl-A3
| An copper-aluminum containing higher content of iron(Fe) than Aluminum Bronze A2 for higher strength. This alloy is used joining and repair welding of aluminum bronze castings of similar composition, and for depositing bearing surfaces and wear-and corrosion –resistant surfaces. |
Phosphor Bronze | AWS 5.7/5.8:ERCuSn-A DIN1733：SG-CuSn6 BS2901：C11 | A copper-tin based welding filler metal containing approx.5% of tin and about 0.35 % of phosphor as a kind of deoxidizer. This alloy has high strength and excellent wear and corrosion resistances due to the presence of tin in the alloy. It is suitable for both TIG and MIG welding processes and used for argon arc welding of copper based alloys and brazing of steel. |
Phosphor Bronze | AWS 5.7/5.8:ERCuSn-C DIN1733：SG-CuSn8 BS2901：C11 | A copper-tin based welding filler metal containing approx.8% tin for higher hardness and strength .It can be used to join phosphor bronzes of similar composition .It is also useful for joining brasses and ,in some cases, for welding them to cast iron and carbon steel. The higher tin content results in weld metals for higher hardness, tensile and yield strength. |
Nickel Aluminum Bronze | DIN1733：SG-CuAl8Ni2 BS2901：C29 | A nickel-aluminum bronze containing about 2%of nickel. Having good wear and corrosion resistances, this alloy is used for joining and repairing bronze metals with similar compositions. It can be used for argon arc welding of copper based alloys and brazing of steel. |
Nickel Aluminum Bronze | AWS 5.7/5.8:ERCuNiAl DIN1733：SG-CuAl8Ni6 BS2901：C29 | A very popular filler metal used in offshore technology such as seawater desalting, shipbuilding and repair .Having increased resistance to wear and corrosion, it is always used in shipbuilding and pump building ,joining and repairing of cast or wrought nickel-aluminum bronze base metals. |
Manganese Nickel Aluminum Bronze | AWS 5.7/5.8:ERCuMnNiAl DIN1733：SG-CuAl13Al7 BS2901：C22 | A manganese- nickel- aluminum bronze filler metal used for joining and repairing of cast or wrought base metals of similar compositions. This filler metal may also be used for surfacing applications where high resistance to corrosion, erosion, or cavitation is required. |
Cupronickel | AWS 5.7/5.8:ERCuNi DIN1733：SG-CuNi30Fe BS2901：C18 | A copper-nickel filler metal used for joining and overlay welding of cooper nickel alloys. The addition of 30% of nickel strengths the weld metal and improves the corrosion resistance, particularly against the salt water. The inclusion of controller quantity of iron also gives the alloy an extraordinary resistance to general corrosion and stress cracking, as well as to erosion. It is suitable for MIG,TIG, oxyacetylene and submerged arc welding of wrought copper nickel70/30, 80/20 and 90/10 alloys to themselves or to each other. |
Naval Bronze (Flux-coated & Bare) | AWS 5.7/5.8:RBCuZn-A DIN1733：SG-CuZn40Si BS2901：CZ6 | A filler metal used for brazing or oxyacetylene welding of steel ,cast iron, malleable iron,copper alloys and nickel alloys.The addition of tin improves strength and corrosion resistsnce on the weld deposit.A borax-boric acid flux is generally required.Flux coating is different coloors can be supplied as requested. |
Low Fuming Bronze（FC&Bare） | AWS 5.7/5.8:RBCuZn-C DIN1733：SG-CuZn40Si BS2901：CZ6 | A low-cost gener-purpose, versatile oxyacetylene brazing alloy used for steels,copper alloys,cast iron,nickel alloys and stainless steel.It is used with the torch,fuenace, and induction brazing processes. Flux is requires and a borax-boric acid flux is commonly used.Flux is required,and a borax-boric acid flux commonly used.Flux coating in different colors can be supplied as requested. |
Nickel Sliver(Flux-coated&Bare) | AWS 5.7/5.8:RBCuZn-D DIN1733：L-CuZn42Ni BS2901：CZ8 | A brazing alloy containing about 10% of nickel. It is primarily used for brazing tungsten carbides, copper alloys, nickel alloys, stainless steels, carbon steels, and cast iron. It is commonly used for building-up or overlaying worn parts such as gear teeth, bearings and valve seats. A boric acid or borax flux is required. Flux coating in different colors can be supplied as requested. |
