Cupola malleable iron is a blackheart malleable iron that is produced by cupola melting and is used for pipe fittings (probably in ANSI G49.1 I think) and similar thin-section castings.
The essential purpose of melting is to produce molten iron of the desired composition and temperature. For gray iron, this can be accomplished with various types of melting equipment. Cupolas and induction furnaces tend to be the types most commonly found in the gray iron foundry. The cupola was traditionally the major source of molten iron. However, gradual acceptance of electric melting has reduced the dominance of the cupola.
The following are the Grades of malleable iron specified according to minimum tensile properties (Source: ASM Handbook)

Please enlighten me with your analysis of Cupola malleable iron A 197.
It seems to have low carbon content for malleability.
