CC Inserts
Indexable cemented carbide cutting inserts.
Sludge
Tungsten-bearing grinding sludge from tool production.
Swarf
Machining swarf carrying recoverable tungsten.
Morgan Rolls
Carbide rolls and roll rings from rod and bar mills.
W Crucibles
Tungsten crucibles and furnace components from high-temperature process plant.
Swarf (bulk)
Loose swarf received in bulk for sorting and analysis.
Grade reference
10 grades, with nominal composition as published.
Reference values for identifying material, not a purchasing or supply specification — see the note under each table.
