Copper

Introduction of Copper

Copper is listed as Cu (atomic number 29) on the periodic table and is an excellent conductor of electricity and heat, second only to silver. Commercially available copper is typically more than 99% pure. The remaining 1% is usually impurities such as oxygen, lead, or silver.

Copper is well known for its electrical and thermal conductivity. It is very resistant to corrosion and is also inherently antimicrobial. The power, automotive, medical, and aerospace industries make use of copper specifically for these properties. Select Copper CNC machining in the BatCNC™.
