Brass Plated Copper Wire Description

Brass Plated Copper Wire is a specialized EDM (Electrical Discharge Machining) wire designed to deliver high performance in precision machining applications, particularly on Charmilles machines. It features a high-purity copper core with a uniform brass coating, combining the excellent electrical conductivity of copper with the enhanced surface hardness and corrosion resistance of brass.

This wire is engineered for high-speed cutting, offering significantly faster machining speeds compared to standard brass wire. Its stable discharge characteristics contribute to consistent performance and high precision, making it especially suitable for processing hard workpieces or demanding production environments.

Due to its physical properties, Brass Plated Copper Wire excels in applications where cutting efficiency and accuracy are critical. However, it is not compatible with automatic wire threading systems, which may limit its use in fully automated setups.

The brass coating not only improves wear resistance but also reduces wire consumption, leading to improved cost efficiency over time. Overall, this wire type is an excellent choice for users seeking to enhance cutting speed and stability without compromising on surface quality or dimensional accuracy, particularly in semi-automated or manual wire EDM operations.

1.       Common Preparation Methods

Brass Plated Copper Wire is typically produced through an electroplating process. First, high-purity copper wire is drawn to the desired diameter and thoroughly cleaned to remove any surface impurities. The cleaned copper wire is then passed through an electrolytic bath containing a brass solution, where a thin, uniform layer of brass is deposited onto the surface through controlled electrochemical reactions. The plating thickness and quality are carefully monitored to ensure consistent performance and adherence. After plating, the wire is rinsed, dried, and annealed if necessary to achieve the required mechanical and electrical properties. The final product is then spooled and inspected for quality assurance before packaging.
