What is copper?
Copper is a highly conductive metal renowned for its excellent electrical and thermal conductivity, malleability, and resistance to corrosion. As one of the oldest known metals, copper has been used for thousands of years in various applications, from electrical wiring to plumbing. Its unique properties make it an ideal choice in industries such as electrical, construction, and electronics. Copper is often alloyed with other metals like zinc (to form brass) and tin (to form bronze) to enhance its mechanical properties. Its ability to resist biofouling and its antimicrobial properties also contribute to its importance in plumbing and architectural applications.
