ER1070 aluminum MIG welding wire

Author: Time:2023-05-17

ER1070 is pure aluminum wire with aluminum content ≥99.7% and has good corrosion resistance,
high thermal conductivity and conductive performance and excellent processing properties. However,
the strength of the low.

Uses: used as pure aluminum of argon arc welding and gas welding filler material, widely used in
electrolytic aluminium bus bar and a guide wire connection and electric power, chemical, food etc. industries.

1.welding should be strict and clear the edge of the welding of the oxide film and oil, otherwise it will cause
welding seam welding and cause the hole, slag and other defects.
2 welding can be used for holding molten metal plate, in order to ensure the weld forming, and avoid hot crack.
