Brass, primarily an alloy of copper and zinc, offers excellent machinability—often considered the benchmark against which other materials are measured. Its inherent lubricity allows for highspeed machining, superior surface finishes, and extended tool life, directly translating to costefficient production runs. Components like intricate valve bodies, durable electrical connectors, and lowfriction gears benefit from brass's corrosion resistance, antimicrobial properties, and good strength.

Copper and its highcopper alloys, like tellurium copper, are prized for unmatched electrical and thermal conductivity. CNC machining transforms these materials into precise heat sinks, bus bars, and electrical contacts where minimal energy loss is critical. While pure copper is softer and more challenging to machine than brass, advanced CNC strategies with sharp tools and optimized parameters ensure burrfree, dimensionally accurate parts without compromising the material's essential conductive properties.

The synergy between these materials and modern CNC technology is where expertise truly matters. A proficient machining partner leverages:
MaterialSpecific Toolpaths: Implementing strategies that manage heat and material adhesion.
Optimal Speeds & Feeds: Maximizing efficiency while protecting the material's structure.
