The Properties of Copper

Copper, whose element symbol is Cu (atomic number 29 on the periodic table), has excellent electrical and thermal conductivity, second only to silver. The purity of commercially available copper is usually above 99%. The remaining 1% is usually impurities such as oxygen, lead, or silver.

It is highly resistant to corrosion and is inherently antimicrobial, along with good strength and hardness. Consequently, it’s a popular material useful for automotive, medical, aerospace, and energy industries due to its excellent functional and aesthetic performance.
