Introduction
Copper tungsten carbide composites like TC5 are engineered to combine the strength and durability of tungsten carbide with the superior conductivity of copper. TC5 typically contains about 50% tungsten carbide and 50% copper by weight, making it ideal for applications where both mechanical integrity and efficient heat or electricity transfer are required. Engineers and procurement specialists need to be aware of the available sizes and customizability of TC5 to ensure optimal performance in their projects.
What Is TC5 Copper Tungsten Carbide?
TC5 is a composite material consisting of tungsten carbide grains dispersed in a copper matrix. This unique structure provides several advantages:
- High Hardness: The tungsten carbide component ensures resistance to wear and deformation under stress.
- Excellent Electrical Conductivity: The copper matrix allows for efficient electricity flow.
- Superior Thermal Conductivity: Heat is dissipated quickly, reducing the risk of component failure.
- Good Machinability: While challenging due to its hardness, TC5 can be machined with the right tools and techniques.
These properties make TC5 a preferred choice for demanding applications in both electrical and mechanical engineering.
Typical Applications of TC5 Copper Tungsten Carbide
TC5 is widely used in several key industries:
- Resistance Welding Dies: Ideal for light-duty projection welding where pressures are moderate.
- Electrical Contacts: Used in switches and connectors due to its resistance to arc erosion and stable conductivity.
- Die Inserts and Facings: Employed in projection, flash, and butt welding, as well as electroforging.
- Electrodes: Utilized in spot welding and other electrical joining processes.
The material's ability to withstand high temperatures and resist wear makes it indispensable in many industrial settings.
Available Sizes of TC5 Copper Tungsten Carbide
Understanding the available sizes of TC5 is crucial for specifying the right material for your application. While exact dimensions may vary by manufacturer, the following are typical size ranges for TC5 copper tungsten carbide:
- Round Rods: Commonly available in diameters from 3 mm (about 1/8 inch) up to 40 mm (about 1.6 inches).
- Flat Bars: Available in widths from 3 mm to 50 mm and thicknesses from 3 mm to 25 mm.
- Custom Shapes: Many suppliers offer custom machining of TC5 for die inserts, electrodes, or other specialized tooling.
Below is a summary table of standard size ranges:
| Shape | Size Range (mm) | Size Range (inches) |
| Round Rod | 3–40 | 1/8–1.6 |
| Flat Bar | 3–50 (width) | 1/8–2 (width) |
| 3–25 (thickness) | 1/8–1 (thickness) |
Custom orders are often required for non-standard dimensions, and lead times may be longer for specialized requirements.
Manufacturing and Customization
TC5 copper tungsten carbide is produced using advanced powder metallurgy techniques:
1. Mixing: Tungsten carbide and copper powders are blended in precise ratios.
2. Compaction: The mixture is pressed under high pressure to form a green body.
3. Sintering: The green body is heated to bond the powders together.
4. Infiltration: Molten copper is introduced to fill any remaining pores, resulting in a dense, homogeneous composite.
Quality control is rigorous throughout the process, with microstructural analysis and mechanical testing ensuring consistency and performance.
