Products Introduction
Copper is one of the oldest metal materials. It has excellent corrosion resistance, thermal conductivity, and electrical conductivity. Due to these properties, copper for CNC Copper Parts plays a crucial role in numerous industrial applications.
CNC copper machining is a precision technology utilised by various industries to manufacture copper parts. However, there are some tricks to machining copper parts. This article will introduce information about CNC Machining Copper, its applications, and the things you need to consider before machining.
Different Copper Grades for CNC Machining
1. Pure Copper
Pure copper for Machining Copper is usually soft and ductile. Some low-alloy pure coppers contain a small amount of different alloying elements. This helps change one or more basic properties of pure copper to the desired characteristics. Adding other alloying elements to pure copper also increases its toughness. Pure copper is best for making electrical equipment, like wires and motors. It is also used in industrial machinery like heat exchangers.
2. Electrolytic Copper
Electrolytic copper for CNC Copper Sheet comes from cathode copper. Cathode copper is copper that has been refined by electrolysis. In this process, copper compounds are put into a solution, and enough electricity is applied to purify the copper material. So, most electrolytic copper has fewer impurities than other grades of copper. Its excellent ductility makes it good for electrical applications, such as windings, cables, wires, and busbars.
3. Oxygen-Free Copper
Oxygen-free copper for CNC Machining Parts has almost no oxygen compared to other types of copper. In most cases, oxygen-free copper grades include many high-conductivity electrical copper components. The most common ones are C10100 and C10200. These oxygen-free copper materials are made from high-quality cathode copper by induction melting. During production, the cathode copper is melted under non-oxidising conditions covered by a graphite bath. Oxygen-free copper has high conductivity and is best for high-vacuum electronic devices, like electron tubes and glass-to-metal seals.
Advantages and Limitations
Advantages
Most CNC Machining Copper has good machinability, ductility, and impact strength. They also have high thermal and electrical conductivity, corrosion resistance, and wear resistance. Another advantage of CNC parts is that they can be formed well in both cold and hot working processes. Plus, these parts can be surface-treated in many cost-effective ways.
Limitations
Even though CNC Machining Copper machining has many advantages, there are some downsides. For example, not all copper materials can be spot-welded or arc-welded. Also, different grades of copper have different corrosion resistance. So, some CNC parts can be easily corroded in environments with active substances.
