CORBRONZE 302 G

CLASSIFICATION

DIN 8555: MSG 31-GF-300-C
EN 14700: T Cu1

DESCRIPTION

? Special cored wire for GMAW
? The weld metal is a Cu - Mn - Ni - Al bronze
? Sound, pore free deposits on ferrous and non-ferrous base materials

APPLICATIONS

The building up of aluminium bronze, cladding components undergoing metal to metal wear under high pressure. Especially suited for marine environments. The addition of nickel improves corrosion resistance in heat and rough seawater. Excellent resistance to cavitation and stress corrosion cracking.

Examples
Ship propellers, shafts, guide grooves etc

Stringer or weaved beads
Can be welded gun leading or gun trailing
The use of pulsed current is recommended for improved wetting and bead appearance
Higher currents and voltages can be used, but cause increased element burn-off (particularly Al) and dilution, leading to lower hardness levels.
Use of preheat and working temperatures up to 300°C will help forestall cracking.
