Tungsten karfe: Ƙarshen samfurin ya ƙunshi kusan 18% tungsten gami karfe. Tungsten karfe nasa ne da ƙarfi gami, wanda kuma aka sani da tungsten-titanium gami. Taurin shine 10K Vickers, na biyu kawai zuwa lu'u-lu'u. Saboda wannan, samfuran tungsten karfe (mafi yawan agogon tungsten na yau da kullun) suna da halayen rashin sauƙin sawa. Ana amfani da shi sau da yawa a cikin kayan aikin lathe, tasirin rawar jiki, raƙuman yankan gilashi, masu yankan tayal. Yana da ƙarfi kuma baya jin tsoron annealing, amma yana da karye.
Carbide da aka yi da siminti: na cikin filin ƙarfe na foda. Cemented carbide, wanda kuma aka sani da karfe yumbu, yumbu ne tare da wasu kaddarorin karfe, wanda aka yi da karfe carbides (WC, TaC, TiC, NbC, da dai sauransu) ko karfe oxides (kamar Al2O3, ZrO2, da dai sauransu) a matsayin manyan sassa, da kuma dace adadin karfe foda (Co, Cr, Mo, Ni, Fe.lu, da dai sauransu). Ana amfani da Cobalt (Co) don kunna tasirin haɗin gwiwa a cikin gami, wato, yayin aikin sintiri, yana iya kewaye foda na tungsten carbide (WC) kuma yana haɗawa tare. Bayan sanyaya, ya zama siminti carbide. (Tasirin yana daidai da siminti a cikin kankare). Yawanci abun ciki shine: 3% -30%. Tungsten carbide (WC) shine babban bangaren da ke ƙayyade wasu kaddarorin ƙarfe na wannan simintin carbide ko cermet, wanda ke lissafin 70% -97% na jimlar abubuwan (nauyin nauyi). Ana amfani dashi ko'ina a cikin jure lalacewa, matsanancin zafin jiki, sassa masu jurewa lalata ko wuƙaƙe da kawunan kayan aiki a cikin matsanancin yanayin aiki.
Tungsten karfe na siminti carbide ne, amma siminti carbide ba dole ba ne tungsten karfe. A zamanin yau, abokan ciniki a Taiwan da ƙasashen kudu maso gabashin Asiya suna son amfani da kalmar tungsten karfe. Idan ka yi magana da su dalla-dalla, za ka ga cewa mafi yawansu har yanzu suna magana ne akan simintin carbide.
Bambance-bambancen da ke tsakanin karfen tungsten da simintin carbide shi ne karfen tungsten, wanda aka fi sani da karfe mai sauri ko karfen kayan aiki, ana yin shi ne ta hanyar kara sinadarin tungsten a matsayin danyen tungsten zuwa narkakkar karfe ta amfani da fasahar sarrafa karfe, wanda kuma aka fi sani da karfe mai sauri ko karfen kayan aiki, kuma abubuwan da ke cikin tungsten yawanci 15-25%; yayin da siminti carbide aka yi ta sintering tungsten carbide a matsayin babban jiki tare da cobalt ko sauran bonding karafa ta amfani da foda metallurgy fasahar, kuma tungsten abun ciki yawanci sama da 80%. A taqaice dai, duk wani abu mai taurin da ya wuce HRC65 in dai har gawa ne za a iya kiransa da siminti carbide, kuma karfen tungsten wani nau’in siminti ne kawai wanda ke da tauri tsakanin HRC85 da 92, kuma ana yawan amfani da shi wajen yin wukake.
