Malleable cam khwb cia hlau yog dawb cam khwb cia hlau uas tau raug annealed. Kev kho cua sov annealing hloov cov qauv brittle raws li thawj cam khwb cia rau hauv daim ntawv malleable.

Ua ntej, cov ntsiab lus tseem ceeb cuam tshuam rau kev kho cov nyhuv Mary cov yeeb nkab cov khoom lag luam nrog cov nqi tsim nyog vim tias nws qhov ntau ntawm metamorphism keeb yuav tsum nqaim heev, thiab yog li nyuaj rau stabilize ntau dua cov hlau hlau. Qhov no xav kom cov txheej txheem cuam tshuam yuav tsum siv zog ua kom tsis muaj zog tsawg dua. Kev kho cov nyhuv ntawm malleable hlau yeeb nkab fittings cov txheej txheem loj dua yog cov hauv qab no.
