FCW 404
Hardfacing cupro-aluminium
Beschrijvingen & toepassingen
• Copper-aluminium hardfacing alloy
• Good resistance to metal to metal wear under heavy loads
APPLICATIONS
Suited to surfacing of iron and copper-base materials. Examples Deep drawing dies for stainless steel, aluminium, magnesium and titanium parts
OPERATING CONDITIONS
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.
