Abstract: The invar alloy powder, mixed with different Cu powder contained different content of oxygen, was compacted and sintered into four sorts of DGTM invar-Cu lowexpansion and high conductivity alloy specimens. The mechanical and physical properties of the alloys were tested and analyzed. The behavior of oxygen and its effect mechanism were discussed. The results show that the ultimate strength decreases with the increase of oxygen content, so does the coefficient of thermal expansion(α) whereas the α platform is shortened.
