This Table 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.
