Application Field Analysis
Double-layer metal clad bar material mainly of titanium clad copper is not only ensure material superior conductivity, and with a strong surface corrosion resistance. Widely used in strong corrosion condition of conductive body, such as electrochemical, electroplating, electrolysis, hydrometallurgy, PCB, electric chemical industry, water treatment, ocean engineering, etc.
Electrochemistry and Corrosion Environment Electrode
- Electrolytic industry: Cathode roll used for producing electrolytic copper foil (a key raw material for lithium batteries and printed circuit boards). The titanium layer comes into contact with the corrosive electrolyte, and the copper layer provides high conductivity and thermal conductivity, being one of the most significant applications of titanium-coated copper at present.
- Other electrolytic electrodes: Used in the chlor-alkali industry and hydrometallurgy as insoluble anodes or special cathodes, balancing conductivity and corrosion resistance.
- Cathodic protection system: As an anode bed material, used for corrosion prevention of facilities such as offshore platforms and pipelines; the titanium layer is resistant to seawater corrosion, and the copper layer enhances the efficiency of current distribution.
Special Conductive / Thermal Components
- High-performance electronic devices: Require contacts, connectors or heat dissipation substrates (such as power semiconductor modules) that are highly conductive but resistant to local corrosion.
- Vacuum equipment: Selected vacuum equipment requires components that are both conductive and corrosion-resistant.
- Welding and high-temperature tools: Resistance welding electrodes, electrical discharge machining electrodes, etc. Copper provides excellent conductivity, and a titanium layer prevents high-temperature oxidation or adhesion.
Marine and Chemical Equipment
- Ship and seawater systems: Used for manufacturing seawater coolers, heat exchanger tubesheets, etc. The titanium layer resists seawater corrosion, while the copper layer enhances heat conductivity and reduces costs compared to all-titanium designs.
- Chemical equipment: Reactor linings, agitators, etc., used in situations where both corrosion resistance and rapid heat conduction are required.
New Energy and High Technology Fields
- Hydrogen fuel cell: Bipolar plates or related components, where the titanium layer is resistant to the corrosive environment inside the fuel cell, and the copper layer ensures high conductivity.
- Nuclear industry: Specific nuclear reactors require materials that are resistant to radiation, corrosion-resistant, and possess high thermal conductivity.
Other Special Applications
- Decoration and Architecture: The titanium exterior provides distinctive color and durability, while the copper core offers strength and weight reduction for high-end decorative components.
- Medical Equipment: Combines the biocompatibility of titanium and the antibacterial properties of copper for specialized medical or implantable equipment.
Double-layer Metal Clad Bar Material Conclusion
Double-layer metal composite materials are not merely a simple "1+1". Instead, through advanced composite technologies, they achieve functional integration and performance amplification, successfully resolving the key engineering challenge that a single metal cannot simultaneously meet the requirements of "surface corrosion resistance" and "high conductivity of the bulk". They are particularly suitable for high-end and demanding industrial environments.
Frequently Asked Questions (FAQ)
What is the core advantage of double-layer metal clad bars?
Double-layer clad bars integrate two metals into a metallurgical bond, combining the high electrical and thermal conductivity of the inner core (e.g., copper) with the superior corrosion resistance of the outer layer (e.g., titanium, zirconium, or nickel).
Which substrate and cladding materials can be combined?
Core substrates include Copper (T1, T2), Anaerobic Copper (TU1, TU2), and Aluminum. Outer clad layers include Titanium (Ti), Zirconium (Zr), Nickel (Ni), Tantalum (Tan), and Stainless Steel (304, 316L).
What manufacturing standard is followed for quality control?
Our metal composite bar products are manufactured strictly in accordance with the GB/T 12769-2015 standard to ensure high bonding strength and uniform clad layer distribution.
What shapes and size ranges are available for custom orders?
We offer rectangular profiles (width 20–150 mm × thickness 6–30 mm), circular bars (Φ 8–50 mm), square profiles (10–30 mm), and silk materials (Φ 2.0–8.0 mm), fully customizable upon customer requirements.
What is the standard thickness of the outer clad layer?
The conventional clad layer thickness ranges from 1.0 mm to 2.5 mm, which provides sufficient corrosion barrier protection while maximizing the cross-sectional area of the conductive substrate core.
