英国WA CORBRONZE 301-G铜铝合金焊丝
CORBRONZE 301-G
DIN 8555: MSG31-GF-300-C
EN 14700: T Cu1
• Copper-aluminium hardfacing alloy with additions of Fe, Ni and Mn to improve the mechanical properties.
• Good resistance to abrasion and corrosion.
• Temperature resistance up to 300°C.
Used for pistons for injection of aluminium under pressure, valve seats, and cylinders for paper-making machinery. Suited to surfacing of iron and copper-base materials.

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.
