Features焊条• Castolin Ultimium 8888 is a composite rod consisting of cemented tungsten carbides embedded in a self-fluxing NiCrBSi-alloy. The coating provided by Ultimium 8888 is not only protective but also used as a functional drilling and cutting coating.• This rod is designed for the oxy-fuel process. No additional flux is necessary. The flux is formed trough the matrix metal itself while fusing the rod.• The cemented tungsten carbides are uniformly distributed in the matrix to get a consistent distribution of carbides in the overlay. |
