Intsimbi yeTungsten: Imveliso egqityiweyo iqulethe malunga ne-18% yentsimbi ye-tungsten alloy. Intsimbi ye-tungsten yeye-alloy eqinile, ekwabizwa ngokuba yi-tungsten-titanium alloy. Ukuqina yi-10K Vickers, okwesibini kuphela kwidayimane. Ngenxa yoko, iimveliso zensimbi ze-tungsten (iiwotshi eziqhelekileyo ze-tungsten zensimbi) zinempawu zokunganxitywa lula. Ihlala isetyenziswa kwizixhobo ze-lathe, iinqununu ze-drill drill, i-glass cutter bits, i-tile cutters. Yomelele kwaye ayoyiki ukurhoxobisa, kodwa ibhityile.
I-carbide enesamente: yeyentsimi yomgubo wesinyithi. I-carbide ene-cemented, eyaziwa ngokuba yi-ceramic ye-metal, yi-ceramic eneepropati ezithile zetsimbi, ezenziwe ngee-carbides zetsimbi (WC, TaC, TiC, NbC, njl.) okanye i-oxides yesinyithi (njenge-Al2O3, i-ZrO2, njl.) njengezona nxalenye ziphambili, kunye nesixa esifanelekileyo somgubo wesinyithi (Co, Cr, Mo, Ni, Fe, njl.) yongezwa nge-powder metallurgy. I-Cobalt (Co) isetyenziselwa ukudlala i-bonding effect kwi-alloy, oko kukuthi, ngexesha lenkqubo ye-sintering, inokujikeleza i-tungsten carbide (WC) powder kwaye idibanise ngokuqinileyo. Emva kokupholisa, iba yi-carbide enesamente. (Isiphumo silingana nesamente kwikhonkrithi). Umxholo udla ngokuba: 3% -30%. I-Tungsten carbide (WC) iyona nxalenye ephambili emisela ezinye iimpawu zetsimbi ze-cemented carbide okanye i-cermet, i-akhawunti ye-70% -97% yamacandelo apheleleyo (umlinganiselo wesisindo). Isetyenziswa ngokubanzi kwiindawo ezinganyangekiyo zokunxiba, ukumelana nobushushu obuphezulu, ukugqwala okanye iimela kunye neentloko zesixhobo kwiindawo ezisebenza nzima.
Intsimbi ye-tungsten yeye-carbide enesamente, kodwa i-carbide enesamente ayiyonyani intsimbi ye-tungsten. Kule mihla, abathengi baseTaiwan nakuMzantsi-mpuma weAsia bathanda ukusebenzisa igama elithi tungsten steel. Ukuba uthetha nabo ngokweenkcukacha, uya kufumanisa ukuba uninzi lwabo lusabhekisa kwi-carbide enesamente.
Umahluko phakathi kwentsimbi ye-tungsten kunye ne-cemented carbide kukuba insimbi ye-tungsten, eyaziwa ngokuba yintsimbi ye-speed-speed okanye isixhobo sensimbi, yenziwe ngokudibanisa i-tungsten iron njenge-tungsten ekrwada i-tungsten ekrwada kwintsimbi etyhidiweyo usebenzisa iteknoloji yokwenza i-steelmaking, eyaziwa ngokuba yi-high-speed steel okanye isixhobo sensimbi, kunye nomxholo we-tungsten udla ngo-15-25%; ngelixa i-carbide ene-cemented yenziwe nge-sintering tungsten carbide njengomzimba oyintloko kunye ne-cobalt okanye ezinye iintsimbi ezidibeneyo zisebenzisa iteknoloji ye-metallurgy ye-powder, kwaye umxholo wayo we-tungsten uhlala ungaphezulu kwe-80%. Ngamafutshane, nayiphi na into enobulukhuni obudlula kwi-HRC65 ukuba nje iyingxubevange inokubizwa ngokuba yi-cemented carbide, kwaye intsimbi ye-tungsten luhlobo nje lwekhabhide enesamente enobulukhuni phakathi kwe-HRC85 nama-92, kwaye isoloko isetyenziselwa ukwenza iimela.
