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.

ER1070 is an **aluminum filler metal** characterized by its high purity, typically containing a minimum of 99.7% aluminum. This makes it part of the 1xxx series of aluminum alloys, known for their excellent electrical and thermal conductivity. It is designed for welding commercially pure aluminum and certain aluminum alloys where maintaining high conductivity in the weld joint is crucial.
The key differentiator for **ER1070** is its high purity and minimal alloying elements, unlike ER4043 (which contains silicon) or ER5356 (which contains magnesium). This composition gives ER1070 superior electrical and thermal conductivity, making it unsuitable for welding heat-treatable alloys like 6061 but ideal for applications demanding high conductivity. Its mechanical strength is lower compared to alloyed **aluminum welding wires**.
The primary applications for **ER1070 aluminum welding wire** revolve around situations requiring high electrical and thermal conductivity. This includes welding electrical conductors, busbars, heat exchangers, and other components in electrical and electronic industries. It's also used in the fabrication of chemical processing equipment where high purity aluminum is required, making it a niche but vital **aluminum welding solution**.
Generally, **ER1070** is not recommended for structural aluminum applications. Its low alloying content results in a weld deposit with relatively low tensile strength and hardness compared to those made with more alloyed filler metals like ER4043 or ER5356. For structural integrity, especially with **6000 series aluminum** or **5000 series aluminum**, other filler metals that offer higher strength are typically preferred.
ER1070 **aluminum welding wire** is primarily compatible with Gas Tungsten Arc Welding (GTAW or TIG) and Gas Metal Arc Welding (GMAW or MIG). For optimal results with this **pure aluminum filler**, it is crucial to use a high-purity shielding gas, typically Argon, to prevent oxidation and ensure a clean, stable arc. Proper **welding parameters** are also vital to minimize porosity and maintain the desired properties of the weld.
Yes, welding with **ER1070** presents specific challenges. Due to its high purity, it has a narrow freezing range, which can increase its susceptibility to hot cracking if proper techniques aren't employed. Additionally, because it has minimal deoxidizers, thorough cleaning of the base metal is even more critical to prevent porosity. Controlling heat input and maintaining a consistent arc are essential for achieving sound **aluminum welds** with ER1070.
The post-weld characteristics of **ER1070** are directly related to its high purity. The weld deposit will exhibit excellent electrical and thermal conductivity, closely matching that of the base material. It will also maintain good ductility. Unlike silicon-containing filler metals, ER1070 welds will not typically turn dark when subsequently anodized, making it suitable for applications where a consistent aesthetic finish is desired on pure aluminum components.
ER1070 offers excellent corrosion resistance, particularly against atmospheric corrosion, due to its high aluminum purity. This makes it a suitable choice for environments where general corrosion is a concern. However, like all aluminum alloys, its resistance to specific aggressive chemicals or saline solutions should be evaluated based on the application, though its inherent purity provides a strong foundation for good **corrosion resistance** in many scenarios.
