\u010eal\u0161ie materi\u00e1ly na tlakov\u00e9 liatie: me\u010f, olovo a c\u00edn<\/h2>\n

Me\u010f, olovo a c\u00edn maj\u00fa pri tlakovom liat\u00ed men\u0161ie, no d\u00f4le\u017eit\u00e9 vyu\u017eitie. Me\u010f je cenen\u00e1 pre pevnos\u0165 a vodivos\u0165.

Me\u010f m\u00e1 vysok\u00fa elektrick\u00fa a tepeln\u00fa vodivos\u0165<\/strong>, preto je vhodn\u00e1 na elektrick\u00e9 a elektronick\u00e9 komponenty.

Formy a stroje na tlakov\u00e9 liatie medi sa preto viac opotreb\u00favaj\u00fa a maj\u00fa krat\u0161iu \u017eivotnos\u0165.

Napriek tomu je me\u010f vhodnou vo\u013ebou, ak sa vy\u017eaduje pevnos\u0165, h\u00fa\u017eevnatos\u0165 a vodivos\u0165<\/strong> v jednom materi\u00e1li.<\/p>\n

Z d\u00f4vodu zdravotn\u00fdch riz\u00edk nie je ani jeden kov vhodn\u00fd pre v\u00fdrobky, ktor\u00e9 prich\u00e1dzaj\u00fa do kontaktu s potravinami alebo pitnou vodou.

Oba kovy sa \u010dasto kombinuj\u00fa s in\u00fdmi, napr\u00edklad so zinkom alebo me\u010fou, aby sa zlep\u0161ila odolnos\u0165 proti kor\u00f3zii<\/strong> a vlastnosti pri odlievan\u00ed. C\u00edn poskytuje ochrann\u00fa vrstvu, ke\u010f sa pou\u017e\u00edva ako povlak.<\/p>\n
