C18200 (chromium-zirconium copper) is an electrode grade in copper alloys. Chromium-zirconium copper combines electrical conductivity, thermal conductivity and high-temperature strength, and is the main material for resistance welding electrodes and heat dissipation substrates.
C18200 has been strengthened by chromium and zirconium aging, maintaining its electrical conductivity at around 80% of IACS while significantly enhancing its high-temperature strength and having a high resistance to softening temperature.
The C18200 (chromium copper) grade is often used in the following fields and scenarios. Our CNC machining services can provide customized parts for these industries.
C18200 (chrome copper) demonstrates the following core advantages in CNC machining and terminal applications.
The following are the key process points when processing the C18200 (chromium-copper) grade to ensure the quality of the parts and processing efficiency.
Select sharp hard alloy or diamond tools with large rake angles and polished cutting edges to overcome the tendency of red copper and brass to stick to the tools.
High speed and large feed rate - Copper alloys have low cutting resistance and fast heat dissipation, which can fully leverage the efficiency of the equipment.
Use emulsion or special cutting oil to wash away the sticky copper chips in time to prevent chip blockage and entanglement.
Hold the surface of soft metal with soft claws or copper sheets for protection to avoid being crushed. For thin-walled parts, pay attention to uniform clamping force.
CMM inspects dimensions and pays attention to surface roughness; Recheck the fit dimensions after post-treatment such as electroplating and oxidation.
Besides C18200 (Chromium-copper, Copper & Brass offers several other grades with different characteristics. Click to view details.
