Installation. If not self supporting, it is screwed or
bolted to structural frame. Joint details are important
because of galvanic corrosion problems when the cast
aluminum comes in contact with dissimilar metals.
Lightweight (1/2 that of cast iron);
Intricate castings possible;
Good delivery time;
Can be prepared for painting in variety of colors;
Less brittle than cast iron.
Lower structural strength than cast iron;
Difficult to prevent galvanic corrosion with other
Greater expansion and contraction than cast iron;
Needs gaskets or caulked joints;
Hard to keep painted.
Can existing materials be repaired or replaced in-
How is cast aluminum to be attached?
Have full-size details been developed for each piece
to be cast?
How are expansion joints detailed?
Will there be a galvanic corrosion problem?
