Ukulawulwa kwembudumbudu yenqubo yokukhiqiza i-hard alloy ngokungangabazeki kungenye yezihluthulelo zokulawula ikhwalithi ye-hardingxubevange, kodwa kunzima kakhulu kusayizi omaphakathi kanye nokunqunywa komthamo kanye nencazelo yokusatshalaliswa okusanhlamvu kosayizi wesigaba esiqinile sokusanhlamvu ku-alloy eqinile.Izinga lamazwe ngamazwe (ISO4499-1978) limemezele kuphela izithombe ezimbalwa ze-hard alloyi-tungsten carbidei-crystal granularity, futhi yisithombe sesigaba segolide esijwayelekile samakristalu aluhlaza, ama-alloys ekristalu amaphakathi namacolekileyo.
Izinga likazwelonke lihlinzeka ngezithombe eziyisishiyagalombili ezinosayizi wezinhlayiyana ezimaphakathi, kodwa ayikho kuzo engaxazulula inkinga yokulinganisa ubumbudumbudu nencazelo.Emashumini eminyaka amuva nje, ubuchwepheshe bezithombe nedijithali buthuthuke ngokushesha.
Zama ukusebenzisa ubuchwepheshe bezithombe zedijithali ukuxazulula izinkinga zayo zokulinganisa.Nokho, ngenxa ibhuloho carbides, ikakhulukazi ultra -fineingxubevange, i-fine crystal skeleton ayikwazi ukucacisa ngokunembile usayizi wokusanhlamvu we-WC.Ukuhlolwa kosayizi okusanhlamvu okungokwesiko kuwumphumela omubi uma kubhekiselwa kumdwebo ojwayelekile.
