Why choose ABRAFIL AlSi12?
AlSi12 solid wire (ABRAFIL AlSi12) is a high-silicon (≈12%) aluminum welding wire, specially designed for the assembly and repair of cast aluminum alloys. It offers excellent castability, good resistance to cracking, and a perfect bead finish, making it the benchmark choice in many industries.
The advantages of AlSi12 welding wire :
-Ideal for cast aluminum alloys: perfectly suited to welding Al-Si parts, such as crankcases, engine blocks, castings, etc.
-Low shrinkage and good resistance to cracking: thanks to its high silicon content, it reduces the risk of hot cracks.
-Excellent melt flow, for clean welds with excellent wetting at the edges.
Clean, aesthetic bead appearance: ideal for visible applications or those requiring few touch-ups.
-Good material compatibility: used with Al-Si, Al-Mg-Si or Al-Cu foundry alloys, in MIG or TIG welding.
Ease of use: easy start-up and good arc stability in the MIG process
