ER1070 aluminum filler wire

Introduction of ER1070 aluminum filler wire
ER1070 aluminum filler wire is pure aluminum wire with aluminum content ≥99.7%. It has excellent corrosion resistance, high thermal and electrical conductivity and excellent processability, but its strength is low.
 
Wire chemical composition of ER1070 aluminum filler wire (%)
AiSiFe≥99.7≤0.20≤0.52
 
Application of ER1070 aluminum filler wire:
ER1070 aluminum filler wire is used as filler material for pure aluminum argon arc welding and gas welding.
 
Precautions for ER1070 aluminum filler wire:
1. Strictly remove the oxide film and oil stains on the welding edge of the workpiece before welding, otherwise it will cause poor welding of the weld and cause defects such as pores and slag inclusions.
2. When welding, a backing plate can be used to support the molten metal to ensure the formation of the weld and avoid hot cracks.
