Elecu® BCu

General description

It is applied for deposit of high resistant layers on surfaces of hot stamps and extruders which, even under considerable loading, shouldn't leave wear tracks on surfaces of deformable details. Mainly, it is applied in automotive industry (car body stamps, stamps of deep stamping, etc.). Layers are deposit on details made of bronze, as well as of cast and usual steel.

Current type

DC electr. +

Application advice

Redry for 2h at 250°C. Before welding joints have to be cleaned from oil and cracks.

Recommendations:

-electrode with small declination (10-20о) along-track direction;

- welding with short arc.

For improvement of deposit degasifying the low speed of welding is applicable. Heavy parts (sections are higher than 6 mm) have to be previously heated to 150-250оС.
