FCW 201
Hardfacing cupro-aluminium
Description & applications
• Copper-aluminium hardfacing alloy that resists abrasion and corrosion up to 300°C.
• The crack sensitivity of the deposit is low.
• Iron, nickel and manganese are added to improve the mechanical properties which are maintained 200°C.
APPLICATIONS
The product is suitable for surfacing of most iron and copper-based materials. It is designed for repairs to bronze castings, slideways, valve covers and for cryogenic applications
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.
