Tungsten Copper Alloy

Custom-Engineered Tungsten-Copper (WCu) Solutions

We specialize in providing fully customized Tungsten-Copper (WCu) components tailored to your exact specifications. As a leading-edge Heat Sink Material, our WCu offers an unparalleled combination of thermal conductivity and mechanical stability. Whether you need a specific thermal expansion coefficient or a complex machined part, our engineering team can deliver a solution that optimizes your Electronics Packaging design.

Technical Specifications

While we offer standard grades, our primary strength is customization. The following properties can be precisely tuned:

• Tungsten Content: 50% to 90% by weight
• Thermal Conductivity (TC): 180 to 340 W/m·K
• Coefficient of Thermal Expansion (CTE): 6.5 to 12.5 x 10⁻⁶/K
• Density: 12.2 to 17.0 g/cm³

Product Features and Advantages

Precision CTE Matching

We can precisely adjust the W/Cu ratio to match the CTE of various semiconductor materials (e.g., GaAs, SiC, AlN, Al₂O₃), minimizing thermal stress and dramatically improving device reliability.

Complex Geometries

Leveraging our advanced CNC machining capabilities, we can produce highly complex shapes with tight tolerances (e.g., planarity to 0.005mm), perfect for intricate Optoelectronic Packaging assemblies.

Integrated Plating Services

Our in-house plating facility provides reliable and consistent surface finishes, including Nickel (Ni), Nickel-Gold (Ni/Au), and selective plating, ensuring excellent solderability for mounting components onto Ceramic Packages.

Application Scenarios

• Custom Microelectronics: Bespoke heat sinks and carriers for specialized ICs and RF modules.
• High-Power Lasers: Precision-machined C-mounts and submounts with specific thermal properties.
• Aerospace & Defense: Components designed to meet unique performance and geometric requirements.
• High-Temperature Tooling: Custom molds and dies that require high wear resistance and thermal stability.

Benefits for Customers

• Optimized Performance: Get a material that is perfectly tuned for your application, rather than compromising with an off-the-shelf solution.
• Reduced Design Cycles: Our expert team works with you to develop the ideal component, saving you time and resources.
• One-Stop-Shop Solution: From material formulation to precision machining and plating, we provide a fully integrated manufacturing service.

Certifications and Compliance

All custom products are manufactured under our rigorous ISO 9001:2015 certified quality management system, ensuring full traceability and adherence to your specifications.

Customization Options

Our customization capabilities are extensive:

• Material Composition: Any W/Cu ratio from 50/50 to 90/10.
• Form Factor: Sheets, plates, rods, blocks, and fully machined 3D parts.
• Tolerances: Machining to dimensional tolerances of ±0.01mm and superior surface finishes (Ra 0.1 μm).
• Plating: Customizable plating layers and thicknesses to meet your assembly requirements.

Production Process and Quality Control

Our process begins with a detailed consultation to understand your needs. We then utilize our advanced powder metallurgy and infiltration techniques to create the base material, followed by precision machining and plating. Each custom part undergoes 100% dimensional and visual inspection.

Customer Testimonials and Reviews

"Their ability to deliver a WCu heat sink with a custom CTE and complex geometry was a critical success factor for our project. The quality and precision were outstanding." - R&D Manager, Defense Contractor

FAQ

Q1: What information do you need to create a custom WCu part?

A1: To start, we need a technical drawing or CAD model with dimensions and tolerances, the desired W/Cu ratio (or target CTE and TC), and any plating requirements.

Q2: What is the typical lead time for custom parts?

A2: Lead time varies depending on the complexity and quantity, but our integrated manufacturing process allows us to offer competitive turnaround times. Please contact us with your specific requirements for an accurate quote.
