Core Product Advantages
Superior Corrosion Resistance, Extremely Low Corrosion Rate
Surface automatically generates a dense, self-healing oxide passivation film, which is stable in sulfuric acid, chloride, and acid-alkali electrolytes for a long time; the annual corrosion rate in copper electrolyte is only 0.011mm thickness: Prevents impurities from precipitating into the electrolyte, ensuring high-purity metal production and eliminating hydrogen embrittlement and perforation failure.
Easy Metal Deposition Layer Peeling
The titanium oxide film naturally isolates the substrate from the deposited metal. The difference in thermal expansion creates interfacial stress, allowing copper plates/foils to be easily peeled off by hand. This eliminates the need for soap-based separators and pre-treatment processes, achieving a peeling yield of over 95% and reducing auxiliary material waste.
High Current Density Capability, Increasing Cell Capacity
Allows for increased electrolytic current density without burnt plates, short circuits, or burr defects. It fully utilizes the electrolytic cell volume, increasing total output without adding new cells. The smooth, flat surface produces high-purity, bright metal foil/cathode plates, meeting the high-end demands of lithium batteries and electronic copper foil.
Application Scenarios
This Grade 2 titanium cathode plate is specifically designed for PCB manufacturing plants and is widely used in electrolytic copper extraction processes involving acidic etching solutions, alkaline etching solutions, and copper-containing wastewater. Suitable for large, medium, and small-scale PCB waste liquid recycling projects, helping enterprises achieve resource recycling and reduce environmental emission pressure.

Frequently Asked Questions
Q1: Why choose titanium cathode plates instead of stainless steel plates for copper recovery from etching solutions?
A1: Stainless steel cathode plates are easily passivated and corroded in high-chloride ion etching solutions, resulting in a short service life and low copper purity. Titanium cathode plates have perfect acid and alkali resistance, passivation resistance, longer service life, and higher copper purity.
Q2: Can the length, width, thickness, and surface finish of the titanium cathode plate be customized?
A2: Yes, we can customize the length, width, thickness, and polishing process of the plate according to your electrolysis equipment and production process.
Q3: Do you provide samples for on-site testing?
A3: We can provide small-sized samples for customers to conduct on-site electrolysis testing. After confirming the recycling effect, bulk orders can be placed.
