I-composite alloy rod yenziwe nge-granular alloy kanye ne-elastic matrix carbide, kukhona ukugeleza okukhethekile ebusweni futhi kunemibala ukuze kubonakale usayizi we-granular. Impahla eyinhloko yosayizi wezinhlayiyana i-tungsten carbide, ubulukhuni obumayelana ne-HRA89-91. Amandla okuqina acishe abe ngu-690MPa
