Pa opaleshoni, ubwino ndi kudalirika kwa sutures opaleshoni ndi zigawo zikuluzikulu ndizofunikira. Chimodzi mwa zigawo zikuluzikulu za sutures opangira opaleshoni ndi singano ya opaleshoni, yomwe nthawi zambiri imapangidwa ndi ma alloys azachipatala monga Alloy 455 ndi Alloy 470. Ma alloy awa amapangidwa makamaka kuti apereke mphamvu zofunikira, zolimba komanso zolimba zomwe zimafunikira pa singano za opaleshoni.

Alloy 455 ndi chitsulo chosapanga dzimbiri cholimba cha martensitic chomwe chitha kupangidwa m'malo ofewa kwambiri. Kulimba kwamphamvu kwambiri, kulimba kwabwino ndi kuuma kumatha kupezeka kudzera mu chithandizo chosavuta cha kutentha. Izi zimapangitsa kukhala chisankho chabwino kwambiri cha singano ya opaleshoni chifukwa imatha kupirira kupsinjika kwakukulu ndi mphamvu zomwe zimachitika panthawi ya opaleshoni. Kuphatikiza apo, Aloyi 455 imatha kupangidwa ngati chitsulo chosapanga dzimbiri komanso kuwotcherera ngati chitsulo chosapanga dzimbiri cholimba chamvula, ndikupangitsa kuti ikhale yosunthika komanso yosavuta kuyipanga.

Aloyi 470, kumbali ina, ndichitsulo chosapanga dzimbiri cha martensitic chomwe chimapereka singano yolimba. Izi ndizofunikira kwambiri pakupangira singano chifukwa zimalola kulowa bwino komanso kuyendetsa bwino pa suturing. Ntchito yowumitsa ntchito ya 470 alloy ndi yaying'ono, ndipo njira zingapo zopangira zozizira zitha kugwiritsidwa ntchito kupanga singano molingana ndi zosowa za maopaleshoni osiyanasiyana.

Kugwiritsa ntchito mankhwalawa kumapangitsa kuti singano ya opaleshoni ikhale yolimba, yokhazikika komanso yodalirika, kuchepetsa chiopsezo cha kusweka panthawi ya opaleshoni. Kuphatikiza apo, kulimba kwamphamvu kwa ma aloyiwa kumapereka singano zopangira opaleshoni ndikuthwa koyenera kuti zitheke kuwongolera bwino komanso kothandiza.

Mwachidule, kugwiritsa ntchito ma alloys azachipatala monga Alloy 455 ndi Alloy 470 mu ma sutures opangira opaleshoni ndi singano kumagwira ntchito yofunika kwambiri pakuwonetsetsa kuti opaleshoni ikuyenda bwino. Ma alloys awa amapereka mphamvu, kulimba komanso kulimba kofunikira pa singano za opaleshoni, zomwe zimawapangitsa kukhala gawo lofunikira pazachipatala.
