Maum hlau malleable, nrum raws li cov hlau dawb, yog kev tsim kho carbide hauv ib lub hlaws dai ntawm lub txiv caj dab. Annealing yog nqa tawm los hloov thawj lub cam khwb cia nkhaus dav hlau qauv rau hauv daim ntawv mallable. Kev kho cov nyiaj pab txhawb ntxiv txhim kho nws cov tshuab luam ntawv machinity, ductility, thiab ruaj khov. Malleable hlau yeeb nkab feem ntau yog tsim los ntawm cam khwb cia hlau thiab cov alloys uas muaj hlau, carbon, thiab silicon. Malleable cov yeeb nkab fittings tau ua haujlwm los txuas ob lossis ntau cov raj lossis cov hlab, hloov cov kev taw qhia ntawm cov kua dej ntws, lossis kaw cov yeeb nkab.
