英国CORBRONZE 100-G铝青铜合金焊丝
CORBRONZE 100-G
DIN 8555: MSG31-GF-150-C
EN 14700: T Cu1
• Aluminium bronze alloy, resistant to corrosion in air to 300°C and to marine corrosion.
• Good resistance to metal-metal abrasion under heavy compressive stresses.
• Retains its mechanical properties to 200°C.
• Deposit not susceptible to cracking.
• May be used both for assembly work and for surfacing.
• Suitable for joining copper base alloys to each other and to iron base.
• Used for constructing machines, chemical installations and in marine constructions.
• Surfacing of slides and slideways, roller guides, valves and pumps.
• Defect repairs in aluminium bronze castings.
• Underlayer for more highly alloyed CORBRONZES (300 and 400 series) where there is a risk of cracking.

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.
