ABSTRACT:
The present disclosure provides alloys having an ultra-low coefficient of thermal expansion in the range of 60° F. to 80° F. The alloys have coefficient of thermal expansion no greater than 0.35×10−6° F.−1in the range of 60° F. to 80° F. Methods of making such alloys also are provided, as well articles of manufacture including such alloys and methods of making such articles.
