Application of Copper Materials
Copper is a reddish-brown metal known for its excellent thermal and electrical conductivity. This makes it one of the most widely used materials in electrical wiring, electronics, and construction. Copper plays a crucial role in CNC machining across a wide range of industries, from electronics and aerospace to architecture and jewelry.
