C42500 Copper tin zinci mixturae introductionis
C42500 mixtura modicam conductionem habet, vires comparandas ad phosphoro aeneo, praestandam lassitudinem perficiendi, et resistentiam bonam induendi. C42500 resistat corrosioni atmosphaerici et marini, nec sentitur ad corrosionem crepitationis accentus. Haec materia aptissima est applicationibus in autocinetis, connectoribus industrialibus et shrapnel.
