Brand Name : | CHENXIANG |
Model Number : | ER4043 |
Product Description
ER4043 is a commonly used aluminum-silicon alloy welding wire (Al-Si12) with good fluidity, crack resistance and welding adaptability, and is widely used in the connection of aluminum alloy materials.
Advantages:
High strength: tensile strength is about 140-160MPa, which is better than pure
aluminum of ER1100.
Good weldability: good fluidity, suitable for filling gaps; strong resistance to
thermal cracking under low heat input.
Moderate corrosion resistance: surface corrosion resistance can be improved by anodizing.
Strong versatility: compatible with a variety of aluminum alloy substrates (such as
1xxx, 3xxx, 5xxx series).
Disadvantages:
Poor conductivity: due to silicon, the conductivity is about 50% of pure aluminum
(about 30% IACS).
Surface treatment required: direct exposure may oxidize, and a protective layer needs to be sprayed or coated.
