Cemented Carbide Composite Rod
- The composite welding rod is made of superior cemented carbide grits in Nickel Silver or Silicon Bronze. Nickel Silver and Silicon Bronze have excellent wettability with the carbide grits. We also use carbide inserts to produce the composite rod.
- Both shape edges and blunt edges are available for different applications. The composite rod with sharp edges is suitable for cutting steel, rock, and other more aggressive application. The composite rod with blunt edges is ideal for grinding and cutting steel and rocks. Typical usage includes fishing tools, centralizers, hole openers), milling tools, and agricultural machinery.
