Description
w 4 ¥/t Metale i stopy, które, szcizególniej w ositat- nich latajch, byly uzywane do spoirzadziaimia obiegowej monety zamiast miedzi, niklu albo bromku, malo odpowiadaly celowi,, gdyz bra¬ kowalo im wiele wlasnosci, wymaganych od metalu monetowego. 'Okazalo sie obecnie, ze stopy, zawierajace obok cynku, jako glów¬ nej swojej1 czesci skladowej, okolo 0,5—2,5%, najlepiej okolo 1,5% miedzi sa zupetoiie od¬ powiednie do zastapienia poprzednich metali i stopów monetowych, posiadaja bowiem du¬ za twardosc, polaczona z nadzwyczajna zdol¬ noscia polituroiwajnia, duza zdolmosc tlocze¬ nia pomimo twardosci i, co jest szczególnie wazne, daleko idaca odpornosc na dzialanie powietrza, wilgoci i soli. Podczais gdy czy¬ sty cynk zanieczyszcza tlok menniczy, to przy nowym stopie niema to miejsca. Zaleta njlonet z podanego stopu jest i to, ze one, po- dolbinie jak niklowe i mieldziiaine mionety, a w przeciwienstwie do moinet a zelalzal, przedstawiaja wartoscj jako metal. PL PLat 4 / t The metals and alloys which, especially in the most recent years, were used in the circulation of the coin instead of copper, nickel or bromide, barely fit the purpose because they lacked much of the properties required of coin metal. It has now turned out that alloys containing, in addition to zinc, as their main component, about 0.5-2.5%, preferably about 1.5%, of copper are quite suitable for replacing previous metals and coin alloys, because they have a high hardness, combined with an extraordinary polyurethane ability, a high pressability despite their hardness and, what is particularly important, a far-reaching resistance to the action of air, moisture and salt. While pure zinc contaminates the mint piston, this is not the case with a new alloy. The advantage of njlonets from the given alloy is that they, like nickel and copper muffins, and unlike moinets and iron, represent value as a metal. PL PL
