ER 1070 refers primarily to a high-purity aluminum welding wire (Al99.7) known for excellent corrosion resistance, high electrical/thermal conductivity, and good ductility, used for welding 1000 series aluminum grades, busbars, and decorative items, though "ER 1070" can also describe specific steel grades or automotive hardeners, so context matters.
Type: Commercially pure aluminum (Al99.7) filler metal.
Properties: High electrical and thermal conductivity, excellent corrosion resistance (especially in alkaline environments), good ductility, and machinability.
Applications: MIG/TIG welding of 1000 series aluminum (grades 1050, 1060, 1070, etc.), busbars, conductors, tanks, boats, and general fabrication.
Characteristics: Produces welds with good color match after anodizing and requires clean base metal to avoid porosity.
Other Uses of "ER 1070"
Steel: AISI 1070 is a medium-carbon steel (around 0.70-0.80% carbon) used in applications needing hardness and edge retention, contrasting with softer steels.
