When sourcing aluminum welding wire for MIG (GMAW) or TIG (GTAW) applications, consistent wire quality, reliable delivery, and responsive support are key to keeping production on schedule and weld integrity intact. Our Aluminum Welding Wire product line is manufactured in Hebei, China under documented process control, supplying ER4043, ER5356 and related aluminum alloy filler metals that conform to AWS A5.10 / ISO 18273 standards.
Overview of Our Aluminum Alloy Welding Wire
We produce solid, non‑flux‑cored aluminum welding wires and TIG filler rods in the most requested alloys:
ER4043 (Al‑Si 5%) – Aluminum‑silicon alloy wire with good fluidity and reduced hot‑cracking tendency; commonly used for 6xxx‑series (6061, 6063), 3xxx and cast aluminum.
ER5356 (Al‑Mg 5%) – Aluminum‑magnesium alloy wire offering higher tensile strength and very good corrosion resistance; widely chosen for 5xxx‑series (5052, 5083) and marine‑environment fabrications.
ER1100 / ER1070 – Commercially pure aluminum wires for welding 1xxx series and for electrical/thermal conduction applications.
ER5183 / ER5556 – Higher‑Mg variants for critical marine and structural aluminum weldments.
Both MIG aluminum welding wire on spools and TIG aluminum filler rods (cut lengths) are available.
Key Performance Customers Value
Stable Wire Geometry & Layer Winding: Precision drawing and controlled cast/helix help prevent bird‑nesting in MIG push‑pull feeders.
Clean Surface, Low Porosity: Degreased and, where specified, vacuum‑packaged to limit moisture pickup—an important factor in avoiding hydrogen‑related porosity.
Good Arc Stability: Formulated to run smoothly with pure argon shielding gas, with manageable spatter and consistent melt‑off rate.
Traceable Chemistry: Each batch is tested for Si, Mg, Fe, Cu, Mn, Cr, Zn and Ti content; Mill Test Certificates (MTC) can be provided per EN 10204 3.1upon request.
Typical all‑weld‑metal tensile strength ranges:
ER4043: ≈ 140–170 MPa
ER5356: ≈ 260–290 MPa
(Actual values depend on base alloy, joint design and welding procedure.)

Why Buyers Work With Us Long‑Term
Manufacturing Oversight in Hebei, China
Production lines in Hebei are equipped for diameter gauging, surface inspection and sample tensile testing. Process records are kept for batch traceability.
On‑Time Shipment from Hebei
Orders are scheduled realistically at confirmation. Finished goods are usually dispatched from Tianjin or Qingdao ports, with shipment notices and photos provided before container loading.
Commitment You Can Count On
We honor quoted specifications and delivery dates. If an issue arises, we communicate early and propose workable solutions rather than leaving you uninformed.
Attentive Pre‑ and After‑Sales Service
Our staff can assist with alloy selection (e.g. when to choose ER4043 vs ER5356), spool size matching to your feeder model, and basic parameter suggestions for your welding procedure. Emails and RFQs are normally answered within one working day.
Flexible Mixed Loading
Aluminum welding wire can be consolidated in the same container with stainless steel welding wire, cobalt base hardfacing wires, abrasion resistant flux cored wires, and silver brazing alloys to help optimise freight cost.
