Yuncheng Shuangma Metal Welding Materials Co., Ltd. supplies ER4043 aluminum welding wire, an Al-Si alloy containing 5% silicon for industrial MIG and TIG applications. The wire is engineered for low shrinkage and high fluidity, producing stable, crack-resistant welds on 6000-series and casting alloys. Its 5% Si content lowers the melting range, improving puddle control in out-of-position work.
The alloy meets AWS A5.10 standards for aluminum filler metals and is commonly used in automotive, marine, and structural fabrication. Typical tensile strength for ER4043 welds ranges from 180 to 220 MPa, with elongation around 8 to 12%. The wire is supplied in standard diameters from 0.8 mm to 2.4 mm, though exact sizes depend on the order. It is non-heat-treatable, so post-weld strengthening requires cold working.
Primary buyers include fabrication shops, shipbuilders, and automotive component manufacturers requiring corrosion-resistant joins in non-structural applications. The wire suits DCEN polarity for TIG and DCEP for MIG, with argon shielding gas recommended. Confirm spool size and weight with the supplier, as packaging varies by diameter and order volume.

Before ordering, verify the exact alloy designation and chemical composition to ensure compatibility with your base materials. ER4043 is ideal for 6000-series aluminum and castings, but confirm with the supplier if your project involves other alloys. Request a mill test certificate to validate the wire’s silicon and impurity levels.
For logistics, confirm packaging options, as spool sizes and weights vary by diameter. Standard shipping terms for China include FOB Tianjin or Shanghai, but clarify Incoterms with the supplier. Lead times typically range from 15 to 30 days for bulk orders, but this depends on production schedules and port congestion.
Inspect the wire for uniformity in diameter and surface finish upon arrival, as variations can affect feedability. Conduct a weld test on scrap material to check for porosity or cracking. Ensure the supplier provides a material safety data sheet (MSDS) and compliance certificates for AWS A5.10 or equivalent standards.
