Copper Graphite

Carbon Graphite Enhancement with Impregnation

Copper impregnated graphite is a unique composite material of copper and carbon graphite. Imagine weaving tiny threads of highly conductive copper into the microscopic pores of carbon graphite. This intricate process, known as impregnation, unlocks a new dimension of functionality:

• Enhancing Electrical Conductivity: By strategically integrating copper into the carbon graphite matrix, the overall electrical conductivity is significantly boosted. This opens doors to various applications where efficient transmission of electrical current is paramount, such as electrical brushes that transfer current to rotating machinery or current collectors in electrical devices.
• Preserving Strength: While copper enhances conductivity, the impregnation process is meticulously controlled to ensure the inherent strength of carbon graphite remains largely intact. This allows the material to retain its robust structure and withstand demanding mechanical loads, making it suitable for applications requiring both electrical conductivity and mechanical strength.
• Minimizing Porosity, Maximizing Performance: The impregnation process also addresses a natural characteristic of carbon graphite – its porosity, which refers to tiny air pockets within the material. By filling these gaps with copper, the overall porosity is reduced. This translates to improved dimensional stability, meaning the material maintains its shape and size more consistently under various conditions. Additionally, in sealing applications, reduced porosity minimizes the risk of leaks, ensuring reliable performance and preventing potential malfunctions.

Carbon Graphite Enhancement with Copper Powder

Another way to achieve similar improvements in carbon graphite properties is through direct integration of copper powder during the initial production stages. Enhancing carbon graphite with copper powder finely tunes the carbon graphite properties that result in a composite material that meets specific requirements. St Marys Carbon achieves this by integrating copper particles into the graphite powder during the initial stages of production.

By adjusting the ratio of copper powder to graphite, we can achieve desired characteristics such as improved conductivity, thermal stability, or mechanical strength. Following the mixing stage, the composite is then processed through molding, baking, and other necessary steps to produce the final product.

In essence, copper graphite elevates its individual components, emerging as a versatile material specifically designed to excel in applications where both electrical conductivity and mechanical strength are crucial.
