Eleal® 4047 Aluminum electrode
General description
Aluminum electrode. Especially for welding forged and cast aluminium alloys containing more than 7% Si as main alloying element. Also applicable as surfacing electrode. Good weldability, no porosity. Applicable when Al-properties are unknown.
Current type
DC electr. +
Application advice
If the thickness is more than 10 mm,it is advisable to preheat at 150-250оС
