فلزفِلِزٌّ (Lth, IDrd, S, A, O, K, &c.) and فِلَزٌّ and فُلُزٌّ, (Ibn-'Abbád, O, K,) the first of which is what is commonly known, (TA,) White copper (نُحَاس أَبْيَض [app. a sort of bronze in which the relative quantity of the tin is unusually large] whereof are made cast cooking-pots (Lth, O, K, TA) of large size, and mortars in which substances are pounded: (TA:) or the metals; gold and silver and copper and the like: (A'Obeyd, A, O, K: *) or the substance [i. e. recrement] that is removed [or blown away] by the blacksmith's  bellows from molten metals: (S, O, K:) or the dross, or recrement, of iron, (O, K,) that is removed [or blown away] by the blacksmith's  bellows: (O:) or stones: (O, K:) its primary meaning is [said to be] hardness, and ruggedness. (IDrd, O.) الفِلِزَّاتُ [pl. of الفِلِزُّ (not to be mistaken for الفِلَذَاتُ)] signifies The seven metals; namely, gold, silver, copper, iron, lead, tin [thus I here render الأُسْرُبّ], and tutenag [thus I render الخَارصِينِى, following De Sacy and others]. (Kzw.) b2:  And hence, as being likened to the فلزّ above described, (TA,) (tropical:)  A strong, hard, and thick, or coarse, man. (K, * TA.) And (tropical:)  A niggard: (Ibn-'Abbád, O, K, TA:) as though he were hard iron, upon which nothing would make any impression. (TA.) b3:  And A thing upon which swords are tested by striking it therewith. (Ibn-'Abbád, O, K.)
