Ngexesha lenkqubo yokubumba umbaleli oshushu, iqondo lobushushu leplastiki linyibilika lilawulwa ngokuchanekileyo kwinkqubo yokubaleka. Iplastiki inokuqukuqela kwimingxuma ikwimeko efanayo, nto leyo ekhokelela kumgangatho ofanayo. Iinxalenye zokubumba zembaleki ezishushu zinomgangatho olungileyo wesango, uxinzelelo olusezantsi olushiyekileyo emva kokudilizwa, kunye nokuguqulwa okuncinci kwamalungu. Iimveliso ezininzi ezikumgangatho ophezulu emarikeni ziveliswa ngundo wombaleki oshushu.

Kuba i-tungsten-molybdenum kunye nezixhobo zayo ze-alloy zine-conductivity ephezulu ye-thermal, amandla obushushu obuphezulu, ukuxhathisa, ukuxhathisa, kunye nokumelana nokunyuka kwe-corrosion, zizixhobo ezifanelekileyo zokwenza imilomo yembaleki eshushu kwisixhobo sokubumba isitofu esifana noomatshini bokubumba inaliti.
