Product Description
1）High Purity Aluminum: ER1070 contains a very high percentage of aluminum, typically 99.7% or greater. This high purity distinguishes it from alloyed aluminum wires and contributes significantly to its unique properties.
2）Excellent Electrical and Thermal Conductivity: A direct result of its high purity, ER1070 offers superior electrical and thermal
conductivity. This makes it an ideal choice for welding electrical conductors like busbars, as well as heat exchangers and other applications where efficient energy transfer is critical.
3）Superior Corrosion Resistance: It boasts excellent resistance to corrosion, especially against chemical attack and atmospheric conditions. This feature is highly valued in industries like chemical processing, food handling, and marine environments where exposure to corrosive elements is common.
4）Good Ductility and Formability: Welds created with ER1070 exhibit good ductility and formability. The weld metal is relatively soft, allowing it to be shaped, bent, or drawn after welding without cracking. This is beneficial for components that require post-weld fabrication.
5）Excellent Anodizing Match: One of its notable aesthetic features is its ability to provide a good color match after anodizing. The weld bead typically presents a bright, clean, and consistent appearance post-anodization, which is crucial for applications where visual appeal and uniform finish are important.
6）Good Weldability and Arc Characteristics: ER1070 generally offers good weldability when proper cleaning procedures are followed. It produces a stable arc and results in a beautiful, bright weld bead with minimal spatter, contributing to high-quality weld appearances.
