Description

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.

This material data has been provided by AMPCO METAL.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.

Welding Recommendations

Preheating the part to be welded to 250°C is useful, but this may affect the laser welding process

After welding, cool the part slowly. A welding blanket may be used

Extraction of welding fumes is recommended
