Non tungsten carbide continent Cobalt?

Tungsten carbide (WC), praecipue Tungsten Carbide Cobalt (WC-CO), est compositum materia celebratum suum eximia duritia, gerunt resistentia, et versatility per numerosis industriae applications. Saepe referred to as quod cemented carbide, hoc materia typice complectitur 70-97% Tungsten carbide, cum Cobalt faciens usque reliqua pars. Et propria Ratio inter Tungsten Carbide et Cobalt potest esse adaequatum ad consequi desideravit materiam proprietatibus. Superiore Tungsten carbide contentus plerumque enhances duritiam et gerunt resistentia, dum auctus Cobalt contentus improves lenta et inpulsa resistentia.
