Aluminum Alloys (6061, 7075)

Aluminum alloys (6061, 7075) are ideal for electrical CNC machining, thanks to their lightweight properties (reducing equipment weight), good electrical conductivity (aiding heat dissipation), and excellent machinability (enabling precise cuts for tight tolerances). They maintain dimensional stability during processing, critical for electrical components. Commonly used for electrical enclosures (protecting internal parts), heatsinks (dissipating heat from circuits), brackets, and control panel frames—examples include switchgear housings, power distribution units, and high-performance connectors that demand both reliability and precision.

Mill Lead Time: 5–10 days
Finishes: Raw, anodized, bead blasted, polished

Stainless Steel (304, 316L)

Stainless steel grades 304 and 316L excel in electrical CNC machining for their high corrosion resistance (vital in humid or chemical-exposed environments), strong structural integrity, and durability. 304 suits general electrical parts like precision brackets and mounting plates, while 316L, with enhanced chemical resistance, is ideal for cleanroom components. Applications include protective covers for sensitive electronics, connector housings, and grounding plates, ensuring long-term performance in harsh electrical environments.

Titanium (Ti-6Al-4V)

Titanium alloy Ti-6Al-4V is perfect for critical electrical CNC-machined components, offering a high strength-to-weight ratio (reducing bulk without sacrificing strength), excellent corrosion resistance (withstanding moisture and chemicals), and heat tolerance (stable in high-temperature electrical systems). It’s commonly used for mounting supports, high-voltage connectors, and structural frames in aerospace-grade electrical systems, where long-term reliability and resistance to extreme conditions are non-negotiable.

Copper Alloys

Copper and its alloys (e.g., brass, bronze) are indispensable in electrical CNC machining for their exceptional electrical conductivity (minimizing energy loss) and thermal conductivity (efficient heat dissipation). CNC machining ensures precise shapes for tight fits in components like busbars (distributing electrical current), contact plates (ensuring stable connections), heatsinks (cooling circuits), and grounding components. These parts are widely used in switchgear, transformers, and electrical connectors, where efficient energy transfer is critical.
