Dekklokakjarni með sérstökum gúmmíhring, háþrýstingsþol, tæringarþol lokikjarna er í grundvallaratriðum úr koparefni, en vegna koparefnis er hlutfallið verulegt, þannig að það mun hafa áhrif á jafnvægi dekksins og kostnaður við koparefni er hár og ekki mjög umhverfisvernd, svo núna er einhver ventukjarni úr ál.
