NOTE TO READERS
The number of digits in some of the tables is an artifact of the computer program used to
analyze the data. This program furnished tabular output with the same number of decimal places for all
numbers. Thus, the number of digits given in the table does not represent the number of significant
digits in the measured or calculated values.
The letters A, B, 0, ... that follow the reference number in the tables and graphs are used to
distinguish between data on alloys of different composition from the same reference.
Each subsection of the monograph is intended to be self-contained, and usually does not
require the reader to refer to other subsections. However, the table of characterization of materials and
measurements and the list of references are found only at the end of each numbered section. For
example, a subsection on thermal expansion of C10100-C10200 copper is self-contained, except for the
characterization table and reference list found at the end of section 7 on thermal properties.
