This paper is about the copper slider with high electric conductivity and resistance arc. A new copper slider which has enhanced resistance against frictional wear was developed. By alteration of its material components and manufacturing process, its material property has been enhanced. To verify its enhanced wear-resisting capacity, a laboratory test and a field test were carried out. As the laboratory test, a dynamo test was performed and its test result showed that the developed new copper slider had superior wear-resisting capacity to the currently used copper slider. The new one showed double durability of the current one and normal wearing characteristics. A filed test was performed on the Metro subway lines at service by Seoul Metro. The field test showed similar results to those from the laboratory test, which the developed new copper slider has double superior durability and sound wearing patterns. Authors strongly believe that the replacement of the copper slider currently in use by the developed new one will contribute to the economic and efficient operation of the subway line
