What is copper cleansing and passivity?

Copper and copper alloys often require special cleaning in the production process and passivity to remove oxidation, end process residues and contaminant particles and create a protective, stable surface layer. This treatment ensures the purity of the components, reduces the risk of corrosion and makes the components fit for assembly - ready for after-treatment, welding or electronic assembly.

Who is fit?

The target group of the service includes manufacturing plants and industries where copper components must meet high quality requirements: electronic and PCB manufacturers, HVAC and pipe system manufacturers, medical instrument manufacturers, marine and car component manufacturers and custom manufacturers such as watchmakers and jewellery. For each area, the cleaning and passivation process is adapted to the material and end use.

Why is this important?

Prevention of corrosion and stable surface protection prolong the lifetime of the parts and reduce the cost of repairs and guarantees. In addition, the correct cleaning improves electrical conductivity, welding and soldering quality and improves adhesion of adhesives and coatings. The final result is a component that is ready for rapid and reliable assembly .

Main advantages

• Longer working life: important corrosion protection reduces early malfunctions.
• <Packaging suitability: Surface ready for assembly directly on the production line without further processing.
l > <rl Process consistency: trackable and reproducible results for each lot.l >l > < < Product quality increase: better management, stronger interfaces and aesthetic finishing. l > The work is performed according to the characteristics of a particular copper or alloy and the end-use requirements, whether electronic connectivity, high mechanical resistance or aesthetic finishing. Processes are trackable and documented to ensure consistent quality and auditing of products.

Additional values for production line

• Less tolerances: uniform surface reduces the rejection of production volume.
• Speed line: prefabricated parts reduce the need for additional work.
• Compatibility: processes meet industry standards and quality requirements.

How to start?

At first, sample handling of a specific part is recommended, the results of which are documented and analysed in accordance with assembly and corrosion requirements. The samples shall be used to design an optimised cleaning and passivation process, which will ensure that part of the preparation is fit for assembly and will reduce the risks to the industry.

Specific results: to obtain cleaner and more durable surfaces, reduce the working time before assembly and reduce the cost of warranty and maintenance. Final result: Reliable, corrosion-resistant and fitable component that is compatible with your production process.

Please ask for test handling or price offer and return to the production line reliability, stability and longer service life.
