AWS: E Cu Mn Ni Al

DIN 8555/1733:
E 31 -UM – 200 -CN

EN 14700: E Cu 1

Current: = (+)

Al: 7,0 – 9,0

Ni: 1,5 – 2,5

Fe: 2,0 – 3,0

Mn: 13,0 – 15,0

Cu: Rest

For joining and surfacing of nearly all Al-bronzes. especially those with high Mn-content as well as steel and grey cast iron. Because of the high seawater and corrison resistance it is also suited for shipbuilding (marine propellers, pumps and fitings) and in the chemical industry for valves and pumps and all parts where chemical attacks is accompanied by erosion.

The favourable coefficent of friction makes it ideal for surfacing on shafts, sliding surfaces, bearings and dies.

For joining and overlaying copper and copper alloys, phospor and tin – bronzes and copper blades in mechanical plant engineering and ship building. The electrode has very good welding properties and steady arc giving low spatter and porosity-free seams. The slag can easily be removed.

Suitable for following base materials:
ASTM B 103-60 alloy C, ASTM B 103-60 alloy A-B B1
