UTP 32 copper alloys
Classifications basic-coated tin-bronze stick electrode
DIN 1733 AWS A5.6 Material-No.
EL-CuSn7 E CuSn-C (mod.) 2.1025
Characteristics and field of use
UTP 32 is a basic-coated tin-bronze stick electrode for joining and surfacing0n copper tin
alloys with 6 – 8 % Sn, copper-tin alloys and for weld claddings0n cast iron materials and
on steel.
UTP 320 is easy weldable and the slag removal is also easy. The corrosion resistance is
corresponding to identical or similar base bls. Seawater resistant. Very good gliding
properties.

Welding instruction
Clean welding area thoroughly. Ignite stick electrode inclined with scratch start. For wall
thickness of > 8 mm a preheating of 100 – 250 °C is necessary. Hold stick electrode vertically
and weave slightly. Use0nly dry stick electrodes. Re-drying 2 – 3 h at 150 °C.
