Castolin 21 F
CEWELD® E AlSi 12 is for joining aluminum alloyed with copper, silicon, and magnesium.
Also excellent for joining dissimilar grades of aluminum.
For welding broken gear parts and or other casting parts, also ideal for cladding or rebuilding wornout parts, Engine blocks, cylinder heads, tanks, containers, frames, lorry tipper.
