In high-humidity, high-salinity or chemically aggressive environments, the corrosion resistance of copper tubes is critical to system reliability and long-term performance. At YEXIANG, we have refined our production process to enhance corrosion resistance in three key areas:
1. Advanced Copper Alloy Composition
Our company specialises in the production of corrosion-resistant alloys, which are created using a unique process that involves the combination of high-purity electrolytic copper and trace elements such as silver (Ag), tin (Sn), and phosphorus (P). These materials form a stable matrix that limits oxidation and degradation, making them ideal for marine and HVAC applications.
2. Surface Treatment Technology
We apply chemical passivation and ultra-thin epoxy coatings (≤20μm) to form a protective barrier on the surface. This layer effectively shields the copper from corrosive agents while maintaining optimal thermal conductivity.
Performance: The product has demonstrated a minimum of 500 hours of resistance to neutral salt spray testing.
3. The Precision Annealing Process
Multi-stage thermal treatment in protective atmospheres (e.g. nitrogen or argon) is an effective method of reducing micro-cracks and internal stress points, which are two common causes of corrosion. This results in a denser, more uniform grain structure with enhanced durability.
This product has been designed to ensure its longevity.
Reliability is assured at every stage of the process, from materials to manufacturing. Our copper tubes are engineered to withstand the harshest conditions, reducing maintenance costs and extending service life.
