Fecrak nobis specimen stannum cum nimia certae reali resistentiae (1.20-1.30 ohm-mm2/m) quae resistentiam caloris usque ad 1450C componit et affirmatur necessariam esse ad extremas temperaturas. Hae proprietates permittunt utentes hoc mixtura late dum unitates calefactionis fabricantes . Resistentiam mordax perfectam aeri, in argonis, in vacuo, oxidizing, sulphureo continens et carboniferos ambitus habet. Ostendit densitatem relativam non valde altam (7.2g/cm3), sed magnum habet modum cedentis.
