Products Description
1. Balancing "Exceptional Corrosion Resistance" with "Ultra-High Conductivity"
Outer Titanium Layer: Acts as a barrier against acids, alkalis, electrolytes, chloride ions, and corrosive chemical media, offering the same level of corrosion protection as pure titanium.
Inner Copper Core: Ensures efficient conduction of high currents, low electrical resistance, and high thermal conductivity-delivering the superior conductive performance characteristic of pure copper.
Dual Functionality: Simultaneous corrosion protection and electrical conduction-combining the distinct advantages of both metals.
2. Significantly Reduced Overall Costs & Exceptional Value
Alternative to Pure Titanium Components: Titanium is an expensive material; consequently, solid titanium conductive rods or plates carry extremely high manufacturing costs. Titanium-clad copper utilizes titanium only for the surface layer while employing more affordable copper for the core, resulting in a substantial reduction in overall cost.
Alternative to Coated Copper: Conventional anti-corrosion coatings-such as electroplating or paint-applied to standard copper are prone to peeling, damage, and premature failure. In contrast, the titanium layer in titanium-clad copper is metallurgically bonded to the substrate, ensuring permanent corrosion protection.
3. High Bonding Strength: No Cracking, No Delamination, Fully Machinable
Advanced Bonding Process: Utilizing explosive bonding or hot-rolling techniques to achieve a metallurgical bond, the titanium and copper are fused together at the molecular level. This allows for cutting, drilling, bending, machining, and welding without issues such as peeling, detachment, or delamination. Its structural stability far surpasses that of components produced via simple adhesive bonding or mechanical cladding methods.
4. Reduced Equipment Wear & Extended Service Life
Enhanced Durability: Pure copper suffers from rapid corrosive degradation in environments involving electrolysis, electroplating, or hydrometallurgy, necessitating frequent replacement and maintenance shutdowns. Titanium-clad copper offers superior resistance to both corrosion and erosion, extending its service life by several orders of magnitude. This minimizes production downtime caused by component replacement and significantly reduces long-term maintenance costs.
5. Stable Electrical Resistance: Safer Operation in High-Current Environments
Reliable Conduction: The copper core features an ample cross-sectional area, ensuring stable electrical conduction, minimal heat generation, and low voltage drop. Unlike pure copper-which tends to corrode and thin out over time in corrosive environments (leading to increased resistance, overheating, and potential fire hazards)-titanium-clad copper maintains stable electrical properties, ensuring a safer environment for industrial power applications.
6. High-Temperature & Oxidation Resistance: Wider Range of Applications
Robust Performance: The titanium layer resists oxidation at high temperatures and exhibits excellent thermal stability. This makes the material suitable for a broad spectrum of applications-including electrolytic cells, chemical processing equipment, humid and saline-mist environments, and outdoor corrosive settings-in conditions where pure copper would be entirely unsuitable.
7. Optimized Weight and High Installation Adaptability
Compared to solid titanium profiles, titanium clad copper is lighter in weight, making it easier to install and handle. Furthermore, when compared to pure copper, it eliminates the need for frequent thickening to provide a corrosion allowance in corrosive environments, resulting in a lighter-weight structural design.
8. Highly Specialized and Customizable for Industry-Specific Applications
Available in various forms-including titanium clad copper rods, plates, and busbars-as well as custom-shaped components, electrode conductor rods, and busbars. Key parameters such as thickness ratios, titanium layer thickness, and copper grade (T2/TU1) can all be customized to meet the specific requirements of industries such as electroplating, metallurgy, new energy, chemical manufacturing, and environmental protection.
