For Copper & Copper Alloys

LoTherme-533 is distinguished by good welding properties. With steady arc and low spatter losses it gives dense, pore-less seams. The slag is easily removed.

LoTherme-533 for joining copper and copper alloys, phosphorus and tin-bronzes as well as copper-clad plates in mechanical and plant engineering and ship building. For surfacing on copper and copper alloys, phosphor and tin-bronzes.

Ultimate Tensile Strength : 314 MPa

Elongation (L=4d) : 30 %

Seam preparation with large V angle (80-90°). Electrode guided vertical, arc 3-4 mm. Only work-pieces more than 5 mm need preheating up to 100 - 250°C. Bronze castings must be cooled slowly. Electrodes that have got damp must be dried 2 to 3 hours at 150°C.
