Cu Sn W/R

EN ISO 24373 - S Cu 1898 (CuSn1)
AWS A5.7: ER Cu

Description

Oxygen-free copper alloy with alloyed elements such as silicon, tin and manganese suitable for GMAW and GTAW copper alloys welding. The alloyed elements improve the weldability without reducing the electrical conductivity. Phosphorus and silicon have a deoxidizer action.

Application

Suitable for joining OF-copper and copper materials subject to high strain. Easily workable. In case of high thickness, it is recommended to preheat to 300 °C.

Cu Si 3 W/R

EN ISO 24373 – S Cu 6560 (CuSi3Mn1)
AWS A5.7: ER CuSi-A

Description

Copper Si alloy, with a controlled Si content (2.80%-3.20) in order to avoid welding defects. For GMAW/GTAW welding on low-alloyed CuMn, CuSiMn and CuZn materials. High temperature and corrosion resistance. Thanks to its melting range and weldability this alloy reduce the finishing operation after welding.

Application

Suitable to weld oxygen-free copper and Cu materials. Used also for galvanized steel GMAW brazing and laser brazing. In case of high thickness, it is recommended to preheat to 300 °C.

Cu Sn 6 W/R

EN ISO 24373 – S Cu 5180A (CuSn6P)
AWS A5.7: ER CuSn-A

Description

High tin alloyed bronze to weld bronze of similar composition; very often used to join copper with steel. Used for cast iron hardfacing.

Application

Suitable to weld CuSn alloys, CuSnZnPb cast alloys and cast iron. For GMAW brazing on steel it is recommended to use a pulsed arc. Excellent for artistic foundries.

Cu Al 8 W/R

EN ISO 24373 – S Cu 6100 (CuAl7)
AWS A5.7: ER CuAl-A1

Description

Wire and rods for GMAW and GTAW copper alloys welding, especially for aluminium bronze alloys. Suitable also for welding of steel and cast iron, porosity free.

Pre-heating is recommended when working with large pieces. Suitable for metal-spraying in we-ar-resistance surface treatment and for welding galvanized steel sheet.

Application

Suitable in shipbuilding industry for pumps, propellers and valves when a high sea water corrosion resistance is required as well as in automotive industry in galvanized sheet welding and in construction industry where high mechanical properties are required.

Cu Al 9 Fe W/R

EN ISO 24373 – S Cu 6180 (CuAl10Fe)
AWS A5.7: ER CuAl-A2

Description

Wire and rods for GMAW and GTAW welding copper-aluminium, copper-silicon, copper-mangane-se and some copper-nickel alloys. Filler material used to weld cast irons, tool steel and galvanized sheets. Used in welding high-strenght brass to guarantee a deposit of material with similar proper-ties of the base material. Pre-heating is recommended when working with large pieces.

Application

Suitable in shipbuilding industry for pumps, propellers and valves when a high sea water corrosion resistence is required as well as in automotive industry in galvanized sheet welding and in construction industry where high mechanical properties are required.

Cu Ni 30 Fe W/R

EN ISO 24373 – S Cu 7158 (CuNi30Mn1FeTi)
AWS A5.7: ER CuNi

Description

Wire and rods for GMAW and GTAW welding copper-nichel alloys containing 10-30% Ni.

Application

Particularly suitable for high stressed corrosion resistant weld surfacing on cast iron and on unal-loyed and lowalloyed steel as well as seawater resistant CuZn alloys. Suitable for welding on CuNi materials. Particularly recommended for the plant engineering. Due to the resistance to sea water the alloy is suitable for off shore applications, ship building, chemical and food industry and oil refineries.
