Cast iron and ductile iron pipe was long a lower-Expense alternative to copper, just before the arrival of tough plastic materials but special non-conductive fittings have to be utilized wherever transitions are being manufactured to other metallic pipes, except for terminal fittings, so as to steer clear of corrosion owing to electrochemical reactions amongst dissimilar metals (see galvanic mobile).[15]
