CNC Copper Contact Block Precision Machined Electrical Connector for Power Equipment
This custom-machined copper component is manufactured from high-purity red copper, ensuring superior electrical conductivity and outstanding thermal performance. Utilizing state-of-the-art CNC machining centers, each part is crafted with precise dimensional control, ideal for high-demand power systems and industrial assemblies.
The design features accurately milled edges, clean drilled holes, and a uniform polished surface that enhances the overall contact performance in electrical interfaces. The copper's natural characteristics — excellent current-carrying capacity, low resistivity, and high durability — make this part a preferred solution for power control equipment, industrial automation, switchboards, and energy distribution systems.
