Njira yopangira annealing imaphatikizapo kutenthetsa chitoliro chachitsulo ku kutentha kwina ndikuzizira pang'onopang'ono, zomwe zimathandiza kuchepetsa kupangika kwa ming'alu kapena zolakwika zina muzitsulo. Kutsirizitsa kwakuda kwa annealed pa chitoliro chachitsulo kumatheka pogwiritsa ntchito chophimba chakuda cha oxide pamwamba pa chitsulo, chomwe chimathandiza kukana dzimbiri ndikuwonjezera kulimba kwa chitoliro. Chitoliro chachitsulo choterechi chimagwiritsidwa ntchito kwambiri pomanga nyumba ndi kupanga mipando.
