Copper, a ductile and malleable reddish-gold metal, possesses exceptional thermal and electrical conductivity. When combined with other metals, it forms popular alloys like brass and bronze.

Due to its tendency to oxidize rapidly, copper is classified as a base metal with an atomic number of 29 and symbol Cu on the periodic chart. Notably, the discovery of its alloying capabilities with tin led to the advent of the Bronze Age, during which bronze tools and weapons played a significant role.

The copper used for CNC processing can be classified based on its alloy composition and form. Two common classifications for copper used in CNC processing are:

1. Free-Cutting Copper Alloys: These alloys are specifically designed for improved machinability and ease of CNC processing. They contain additives like lead, sulfur, or tellurium, which form free-machining particles that break up the chips during cutting, resulting in improved chip evacuation and reduced tool wear. Examples of free-cutting copper alloys include C36000 (Free-Cutting Brass) and C14500 (Tellurium Copper).
2. Copper Alloys for Specific Applications: Copper alloys can be tailored to meet the requirements of specific CNC machining applications. For instance, some copper-nickel alloys (e.g., C71500) are highly resistant to corrosion and are used in marine components and heat exchangers. Beryllium copper alloys (e.g., C17200) have excellent strength and conductivity, making them suitable for electrical connectors and springs.

In addition to alloy composition, the form of copper used in CNC processing is also significant. Copper materials can be supplied as solid bars, sheets, tubes, or custom extrusions, depending on the requirements of the CNC machining project.

Selecting the appropriate copper alloy for CNC processing is crucial to achieving the desired precision, efficiency, and performance in various industries such as electronics, aerospace, automotive, and more. Understanding the characteristics of different copper alloys and their suitability for specific machining applications is essential for successful CNC processing.

Due to various reasons, the classification standards of each country are different. If you need specific and detailed information, please contact customer service.
