AMPCO-TRODE® 940 Laser

Description and Application

AMPCO-TRODE® 940 is an alloy developed to provide an effective alternative to beryllium copper. Because of its excellent thermal conductivity, thermal diffusivity, wear resistance and corrosion resistance, AMPCO-TRODE® 940 laser welding filler metal is specified for the repair of complex AMPCOLOY® 940 molds used for the production of plastic parts.

AMPCO-TRODE® 940 laser filler metal is applied with the laser welding process. The nature of this process permits very non-invasive, almost surgical welds, as compared to conventional arc welding.

Due to the very localized temperatures involved, mold distortion generally experienced with conventional arc welding processes are drastically reduced, often near to zero.

Typical applications:

Repair of blow molds and injections molds and their components, such as cores and pins, made in AMPCOLOY® 940.
