This Chart gives typical values of thermal several common commercial metals and alloys.
Values refer
to ambient temperature (0 to 25°C).
All values should be regarded as typical, since these properties are dependent on the particular type of alloy, heat
treatment, and other factors.
Values for specific allots can vary widely.
