Problems solved by technology

Under the action of the above two mechanisms, the corrosion resistance of the Cu-Fe alloy is weakened, and the service life of the alloy is also greatly reduced.
In addition, due to the addition of Fe, it will affect the thermal conductivity of Cu-Fe alloys. The thermal conductivity of traditional Cu-Fe copper alloys is generally poor. It is necessary to improve their thermal conductivity to meet the requirements of high heat-resistant and corrosion-resistant copper alloys. needs
