5-10KG ER1100 Aluminum Welding Wire Welding Wire Supplier AWS A5.10

Product Description

ER1100 is a pure aluminum (Al ≥ 99.5%) gas shielded welding wire, which is widely used in lightweight welding scenarios with high requirements for conductivity and corrosion resistance.

​1. Chemical composition
​Main components: aluminum (Al) ≥ 99.5%, the sum of other elements (Fe, Si, Cu, etc.) ≤ 0.5%.
​

Features: Nearly pure aluminum, no other alloying elements added, so it has excellent conductivity (about 63% IACS) and strong corrosion resistance (especially in oxidizing environments).
​

2. Core characteristics
​Advantages:
​High conductivity: suitable for conductive parts such as power equipment and cable busbars.
​

Excellent corrosion resistance: suitable for marine environments, chemical equipment or structures exposed to air for a long time.
​

Lightweight: low density (2.7g/cm³), reducing structural weight.
​

Non-magnetic: can be used for electromagnetic sensitive parts.

​Disadvantages:
​Low strength: The tensile strength is only about 90-100MPa, which is not suitable for load-bearing structures.
​

Difficult to weld: easy to oxidize (strict inert gas protection is required), high thermal conductivity (small current fast welding is required).
