1. Ubunzima obuphezulu, akukho deformation ----- Ubunzima bensimbi engenasici bungaphezu kwamaxesha ama-2 aphezulu kunobhedu, ngaphezu kwamaxesha angama-10 aphezulu kune-aluminium, ukucubungula kunzima, kwaye inkqubo yokuvelisa inzima.
I-2.I-Durable kunye ne-rusty ---- eyenziwe ngensimbi engenasici, inhlanganisela ye-chrome kunye ne-nickel idala uluhlu lwe-anti-oxidation ebusweni bezinto eziphathekayo, ezidlala indima yokugqwala.
3.Inobuhlobo kwindalo, ayinayo ityhefu kwaye ayingcolisi ------- Izinto zentsimbi engatyiwayo ziye zaqatshelwa njengezicocekile, zikhuselekile, azinatyhefu kwaye zixhathisa kwiiasidi kunye nealkali. Ayikhutshelwa elwandle kwaye ayingcolisi amanzi etephu.
4. Ubuhle, umgangatho ophezulu, osebenzayo -------- Iimveliso zensimbi ezingenasici zithandwa kwihlabathi lonke. Umphezulu wesilivere nomhlophe. Emva kweminyaka elishumi yokusetyenziswa, ayinakuze ivuthe. Ngethuba nje usula ngamanzi acocekileyo, uya kucoceka kwaye ahle, akhanye njengentsha.
