Description

AMPCO-CORE® 250 is an aluminum bronze flux core wire for use with the Gas Metal Arc Welding process.

AMPCO-CORE® 250 is primarily an overlay filler metal. The characteristics of this filler metal make the deposit adaptable for use in those extreme bearing applications where very high pressures are encountered operating against hardened steel surfaces.

AMPCO-CORE® 250 often use for overlaying in applications where it unusual wear-resistant qualities increase service life of wearing parts.

Other

AMPCO-CORE® 250 is available from stock in two diameters: 0.045” (1.2mm) and 0,062” (1.6mm). Both sizes are available in 12″ (300mm) spools weighing 33lb (15 kg) each. Other diameters are available upon request.

Processing methods

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
