Description
Super Silicon No 9 FE – 4 mm x 5 Kg
This rod is square in section. The typical use is for joining castings, building up worn parts, surfacing new castings and for the repair of all cast iron items. Gives excellent colour match.
Some pre-heating may be required before welding (not quite red hot) and a slow cooling rate is preferred, which may be achieved by wrapping the finished component, or immersing it in sand.
Super Silicon No 9 can also be used in TIG welding if the surface has been ground away and angled to a fine point.
