AWS A5.6 – ECUAL-B
Description and Application
AMPCO-TRODE® 160 aluminum bronze coated electrodes produce a deposit of high strength and good ductility with a nominal hardness of 160 Brinell as applied by the shielded metal-arc process.
AMPCO-TRODE® 160 is recommended for joining aluminum bronzes (AMPCO® 18), ferrous and dissimilar metals requiring higher strength than produced by AMPCO-TRODE® 10 filler metal.
The deposit has excellent bearing characteristics and is suitable for overlaying bearing surfaces subject to normal wear and shock. The deposit has properties which make it resistant to “squashing out” in bearing service.
