Manufacturing Processes for Copper Foam

The production of copper foam involves specialized techniques to create the desired porous structure while maintaining the integrity and properties of copper. Several methods are employed, each offering unique advantages in terms of pore characteristics, scalability, and cost. Understanding these processes is key to appreciating the material’s potential and its availability for industrial use in the United Kingdom.

Powder Metallurgy and Sintering

This is arguably the most common and versatile method for producing copper foam. It typically involves mixing copper powder with a pore-forming agent, such as polymer spheres, sugar particles, or gas-generating compounds. This mixture is then compacted into a desired shape and subjected to a high-temperature sintering process in a controlled atmosphere. During sintering, the copper particles fuse together (metallurgical bonding), and the pore-forming agents either burn out or melt away, leaving behind an interconnected network of pores. The size and distribution of the pore-forming agents directly influence the final foam structure. This method allows for precise control over porosity and can be scaled for industrial production, making it suitable for supplying the UK market.

Wire Mesh / Sponge Method

Another popular technique involves using a pre-formed copper sponge or a stack of copper wire meshes as a scaffold. These structures are then infiltrated with molten copper or copper powder, which is subsequently sintered or melted to bond the material together. The original sponge or mesh structure dictates the pore configuration. This method can yield foams with high interconnectedness and good mechanical properties. It is often used for applications requiring high strength and excellent flow characteristics.

Investment Casting with Polymeric Foam Patterns

In this method, a replica of the desired foam structure is created using a sacrificial material, such as a polymeric foam. This foam pattern is coated with a ceramic slurry to form a mold. The pattern is then removed, typically by burnout at high temperatures, leaving a hollow ceramic mold. Molten copper is then poured into this mold, filling the cavity. After cooling and solidification, the ceramic mold is broken away, revealing the copper foam. This technique is effective for creating complex shapes and structures but can be more labour-intensive and costly for large-scale production.

Electrochemical Deposition

This method involves using a template, often a porous polymer or a sacrificial material, and depositing copper onto it electrochemically. Copper ions from an electrolyte solution are plated onto the template under an electric current. Once a sufficient thickness of copper is built up, the template is removed, leaving a copper foam structure. This technique offers good control over pore morphology and surface characteristics but is generally limited to smaller-scale production and specific applications.

The choice of manufacturing process impacts the final properties, cost, and availability of copper foam. Manufacturers in the UK can select the method that best aligns with their specific application requirements and production volumes.
