Welding wires for aluminum - BÖHLER

Aluminum Welding Wires

Welding aluminum and its alloys is specific and requires a high-quality aluminum welding wire to ensure a strong and durable joint. Several types are available – most commonly wires based on AlMg (aluminum–magnesium) and AlSi (aluminum–silicon) alloys. The choice of wire depends on the welded material and the desired weld properties.

✅ Advantages of aluminum wires lie in their ability to create a lightweight yet strong weld with excellent corrosion resistance. At the same time, the joint maintains good mechanical properties even at lower weight, which is especially important in the automotive and aerospace industries.

❌ On the other hand, the disadvantages of welding aluminum include higher demands on material cleanliness – the surface must be free of oxides, oils, and impurities, otherwise weld quality may decrease. Aluminum is also highly conductive, which means it requires precise machine parameter settings and often the use of special feeding systems to prevent the wire from breaking or jamming.

Applications of aluminum wires are very broad. They are used in the production and repair of frame structures, ships, automotive parts, tanks, and pipelines. They are also popular in the energy and engineering sectors, where a combination of low weight and high strength is required.

👉 If you need to reliably join aluminum or its alloys, aluminum MIG/MAG welding wires are the right solution.
