Abstract
There is provided a sintered material of which dimensional accuracy has been increased by improving the sinterability of Cu—Al based sintered material. More specifically, there are provided a sintered material and a composite sintered contact component, which are excellent in strength, wear resistance, seizure resistance and corrosion resistance. The sintered material is a Cu—Al based sintered material containing at least 1 to 12 wt % Sn and 2 to 14 wt % Al, and the composite sintered contact component is formed by sinter-bonding this sintered material to a metal backing.
