Aluminum CNC Machining

Aluminum is our most machined material. Excellent machinability, high strength-to-weight ratio, and natural corrosion resistance make it ideal for aerospace, automotive, EV, and electronics enclosure parts.

6061-T6 Most common — general-purpose structural
7075-T6 Aerospace-grade, higher strength
2024-T3 Aerospace structural, fatigue resistant
5083 Marine-grade, weld-friendly
6082 European structural standard
MIC6 Cast tooling plate, ultra-flat

Finishes available: as-machined, anodize (clear, black, hard-coat Type III), alodine, powder coat. See our aluminum machining page for full details.

Stainless Steel CNC Machining

Stainless steel is preferred for medical devices, food processing equipment, oil & gas components, and applications requiring corrosion resistance and high strength. We machine all common grades with tight tolerances and excellent surface finish.

SS 304 / 304L General-purpose, good corrosion resistance
SS 316 / 316L Superior corrosion — medical, marine
17-4 PH Precipitation-hardened, high strength
SS 303 Free-machining stainless
SS 440C High hardness, bearings & tooling
Duplex 2205 High strength + pitting resistance

Titanium & Alloy Steel CNC Machining

Titanium Grade 2 (CP Ti)

Commercially pure titanium. Excellent biocompatibility and corrosion resistance. Used in medical implants, chemical processing, and marine hardware.

Density: 4.51 g/cm³ — 45% lighter than steel

Titanium Grade 5 (Ti-6Al-4V)

Most widely used titanium alloy. High strength-to-weight, excellent fatigue resistance. Used in aerospace, medical, and motorsport applications.

UTS: 950 MPa — Machining: requires low speeds, sharp tooling

4140 & 4340 Alloy Steel

High-strength chromium-molybdenum steels for shafts, gears, tooling, and structural parts requiring high strength and wear resistance.

Available pre-hardened or annealed — heat treat sourced locally

Tool Steel (D2, H13, P20)

High-hardness tool steels for molds, dies, jigs, and fixtures. Machined in annealed state; hardening coordinated post-machining.

Mild Steel (MS / EN8)

Cost-effective for structural brackets, fixtures, and general engineering components where corrosion resistance is not critical.

Invar / Kovar

Low thermal expansion alloys for precision instruments, optical mounts, and semiconductor equipment components. Available on request.

Brass, Copper & Non-Ferrous Machining

Brass (C360, C260)

Excellent machinability — brass cuts faster and produces better surface finish than most metals. Common for fittings, connectors, valve bodies, and electrical components. C360 (free-cutting brass) is the most machinable alloy available.

Copper (C110, C101)

High electrical and thermal conductivity. Used for bus bars, heat sinks, RF components, and electrical contacts. Requires sharp tooling and controlled cutting speeds for best results.

Bronze (C954 Aluminum Bronze)

High wear resistance and strength. Used for bearings, bushings, and marine applications. Excellent corrosion resistance in seawater environments.

Engineering Plastics CNC Machining

Engineering plastics offer low weight, chemical resistance, and electrical insulation for demanding applications in medical, semiconductor, and food processing equipment.

Delrin / POM (Acetal)

Low friction, high stiffness, excellent machinability. Ideal for gears, pulleys, valves, and precision mechanisms. White and black grades available.

PEEK

High-performance thermoplastic with excellent chemical and temperature resistance (up to 250°C). Used in medical, aerospace, and semiconductor equipment.

PTFE / Teflon

Chemically inert, non-stick surface, low friction. Used for seals, bushings, and laboratory components. Pure or glass-filled grades available.

Nylon (PA6, PA66)

Good strength, moderate chemical resistance, and low cost. Common for structural brackets, spacers, and wear-resistant components. Available natural or glass-filled.

UHMW Polyethylene

Ultra-high molecular weight PE — excellent impact strength and wear resistance. Used for guide rails, liners, and food-safe components.

Acrylic (PMMA)

Optically clear, excellent surface finish when polished. Used for light guides, instrument covers, and display components.
