Passivation polishing is a commonly used process when machining and treating copper and its alloy parts, as it improves the surface finish of the workpiece while enhancing corrosion resistance. However, one of the main challenges often faced in this process is how to achieve a good polish without over-corroding the workpiece. In order to address this issue, this article will look at how to avoid excessive corrosion of copper parts when using passivation polishes in conjunction with Bigely specific product, copper passivation polishing agent BC-80.
Copper and copper alloys are often attacked by acid or other chemicals during chemical polishing. Conventional polishing compounds tend to cause surface corrosion or damage to copper parts. Innovations in chemical formulation and process control can better balance good polishing results and workpiece protection.
In this context, Bigely has launched a passivation polishing agent for copper parts and their alloys, BC-80, which is mainly suitable for bright cleaning of copper and copper alloys. By means of a reasonably formulated chemical composition, the copper passivation polishing agent BC-80 is able to achieve effective polishing of copper parts and their welded parts or other metal fittings (e.g. aluminum, iron, etc.) without excessive corrosion. Its advantage lies in the fact that, while guaranteeing the polishing effect, it can significantly slow down the erosion of the metal surface of the workpiece and prolong the service life of the workpiece.
