AMPCO-CORE® 200
Cored Wire
Description and Application
AMPCO-CORE® 200 is an aluminum bronze flux core wire for use with the Gas Metal Arc Welding process.
AMPCO-CORE® 200 is primarily an overlay filler metal. The high strength values of the deposit combined with excellent wear-resisting characteristics make this alloy unsurpassed for bearing overlays where extreme wear and high pressures are encountered in service.
$900.90 – $905.85
Typical Applications
| Gear teeth | Friction plates | Pump shafts |
| Bearings | Stripper columns | Sliders |
| Wear plates | High speed bearings |
Welding position and deposits
The flat welding position is recommended. Backhand (trailing) welding is preferred rather than forehand (pushing) to make either stringer or weaved beads.
Shielding gas
100% Argon
