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.
