Overview

Copper’s superior conductivity and corrosion resistance make it indispensable in electrical, thermal, and decorative applications. Whether your project is fulfilled in-house or through our Canadian partner network, Pearson Manufacturing manages the entire process — from material selection to delivery — with quality assurance at every step.

Our Capabilities

Our copper machining capabilities — performed in-house or via certified Canadian suppliers — include:

CNC Milling: profiling & contouring of copper blocks, sheets & components
Manual Machining: prototype rework, deburring & precision adjustments
Turning: connectors, pins, rings & electrical parts with tight concentricity
Drilling & Tapping: clean holes & threads in soft material without burring
Threading & Boring: specialty threads & tight-fit bores in copper alloys
Prototype Development: one-off thermal parts, contact surfaces, bus bar blanks
Surface Preparation: chamfering, cleaning & conductivity-safe finishing
Installation Prep: parts machined for drop-in fitment to panels & assemblies

Why Copper?

Exceptional electrical & thermal conductivity for heat transfer parts
Natural corrosion resistance ideal for plumbing & marine environments
Excellent machinability when using optimized feeds/speeds & tooling
Smooth surface integrity for low-contact resistance applications
Recyclable & sustainable material choice for eco-friendly projects

Our Equipment

Equipment listed below is used either at our facility or by our vetted Canadian partners:

3- & 4-axis CNC milling centers with high-speed spindles
Manual lathes & turning centers optimized for soft metals
Precision drill presses & tapping rigs with low-backlash chucks
Boring bars & reaming tools for tight-tolerance bores
Surface & centerless grinders for fine finishes
Polishing & buffing stations for mirror-like copper surfaces

Supported Copper Grades

C110 (ETP) – high conductivity copper for electrical connectors
C145 (Tellurium) – excellent machinability for precision features
C101 (Oxygen-free) – ultra-pure copper for vacuum & sensitive components

Typical Applications

Bus bars, electrical busway & grounding components
Heat sinks, thermal transfer plates & mold inserts
Plumbing fittings, valves & corrosion-resistant hardware
Electronics connectors, contacts & conductive terminals
Decorative trim, architectural hardware & musical instrument parts

Copper FAQ

Which copper alloys do you machine?

We support C110 ETP, C145 tellurium, C101 oxygen-free, and custom alloys on request, optimizing tooling for each grade.

How do you handle copper’s gumming tendency?

By using high-rpm spindles, sharp carbide tooling, and effective coolant flow, we prevent built-up edge and gumming.

What tolerances can you hold in copper?

Typical tolerances are ±0.002″ (±0.05 mm) or better on key features, depending on geometry and alloy.

Can you finish copper for plating or coating?

Yes—we deliver surfaces ready for plating or coating, including polishing and lapping to customer specs.

Is this manufactured in-house?

Some copper parts are produced in-house at our Ontario facility, while others are fulfilled through our trusted Canadian manufacturing partners. Pearson coordinates sourcing, QC, and delivery throughout.
