Titanium copper composite plates

Titanium-copper composite plates

I. Product Overview:

The Titanium copper composite plate is a cutting-edge material designed to meet the rigorous demands of industries that require both high strength and exceptional conductivity. The unique combination of copper and titanium offers remarkable performance under extreme conditions, making it ideal for use in aerospace, automotive, electronics, and energy sectors. This innovative material offers unparalleled corrosion resistance, high-temperature stability, and lightweight properties, setting a new standard for high-performance materials.

II. Product Construction and Basic Specifications

1. Structure and Materials: Typically features a dual-layer structure of titanium cladding over a copper substrate. Certain applications may utilize a triple-layer structure of titanium/copper/titanium. Common material combinations are well-defined: the titanium layer typically employs TA1 or TA2 industrial pure titanium, or TA10 for chloride corrosion resistance; the copper layer primarily uses T2 red copper with conductivity exceeding 99.9% or TUP deoxidized copper for hydrogen embrittlement resistance.

2. Product Specifications: Compliant with domestic and international standards such as GB13238-91 and ASTM B898. Thickness ranges: Titanium layer typically 1–10 mm, copper layer 2–50 mm. Dimensions: Maximum width 2000 mm, length 4000 mm, with custom sizing available for specific operational requirements.

III. Core Performance Advantages

1. Combined Corrosion Resistance and Biofouling Prevention: The titanium coating exhibits a corrosion rate below 0.01 mm/year in highly corrosive environments like seawater and wet chlorine gas, offering a service life 5–10 times longer than stainless steel. Copper ions released from the copper layer effectively inhibit marine organism attachment, reducing fouling by 90% compared to pure titanium plates in practical applications—making it particularly suited for marine environments.

2. Balanced electrical and thermal conductivity: Its overall electrical conductivity reaches 60–80% of pure copper, far exceeding the mere 2% IACS of titanium alloys. Thermal conductivity can attain 54 W/m·K—three times that of titanium-steel composite plates—effortlessly meeting demands in high-heat-load scenarios like electrolytic cells and condensers.

3. High Strength with Lightweight Design: Interface shear bond strength exceeds 85 MPa, far surpassing the national standard requirement of 40 MPa, ensuring resilience under complex operating conditions. With a density only 60% that of pure copper and 40% lighter weight, it significantly reduces transportation and installation challenges and costs.

4. Outstanding Cost-Effectiveness: Initial procurement costs are reduced by 40-60% compared to pure titanium plates.

5. Extended Service Life: For example, titanium-copper composite electrodes used in chlor-alkali plants achieve a lifespan of up to 15 years, reducing annual maintenance costs by 60% and delivering clear long-term economic advantages.

V. Main Production Processes

1. Explosive Bonding Method: Utilizes the energy from explosive detonation to achieve high-speed collision between titanium and copper plates. During impact, oxide films and impurities on both metal surfaces are removed, enabling instantaneous metallurgical bonding. This process yields high interfacial bond strengths exceeding 150 MPa, suitable for producing thick plates over 20 mm total thickness.

2. Rolling Composite Method: Through hot rolling (at 800–900°C) or cold rolling (with 60–70% deformation rate), the surfaces of titanium and copper plates undergo plastic deformation, exposing fresh metal surfaces that bond together. This process is suitable for producing thin plates with total thickness ≤10mm. Cold rolling additionally prevents metal phase transformations, ensuring stable product performance.

3. Explosion-Rolling Composite: First creates a composite slab via explosion technology, then processes it to target thickness through hot or cold rolling as required. This method combines the high bonding strength of explosion bonding with the high dimensional accuracy of rolling, accommodating diverse specification demands.
