Aluminum removes fast, holds a stable dimension once cut, and delivers a strong
strength-to-weight result — which is why it carries most prototype work and a
large share of production parts. It also anodizes and coats cleanly, so cosmetic
housings and brackets finish as well as they function.

Copper moves heat and current better than almost anything else on the shelf, so it
is the default answer for busbars, heat-transfer blocks and current-carrying
hardware. It cuts soft and gummy, which makes controlled feeds and sharp tooling
the difference between a clean face and a torn one.

Rod, plate, tube
Surface Finish Options
Polishing, plating, natural finish
CNC Machining Advantages
Excellent conductivity, good corrosion resistance
Typical Applications

Tolerance Capability
±0.01 mm depending on geometry
Titanium buys you load-carrying strength at roughly half the weight of steel, plus
body compatibility that makes it the material of record for implants. It also fights
back — heat concentrates at the cutting edge and tools wear quickly — so we
run it slow, keep it flooded, and treat tool paths as an engineering decision rather
than a scheduling one.
Machinable Forms
Bar stock, plate, forging, titanium casting
Surface Finish Options
Anodizing (Type II/III), PVD coating, bead blasting, passivation
CNC Machining Advantages
High fatigue resistance, non-magnetic, maintains strength at high temperatures

Surgical implants, turbine blades, deep-sea hardware, racing components
Available Grades
Grade 2 (Pure), Grade 5 (Ti-6Al-4V), Grade 23 (ELI)
Lead Time
7–12 business days
Supported CNC Services
5-axis CNC milling, Swiss turning, EDM, deep-hole drilling
Tolerance Capability
Standard ±0.01mm; Precision ground to ±0.005mm
Bronze CNC Machining
Bronze earns its place in sliding contact: it shrugs off wear, runs with little
friction against a shaft, and resists corrosion in wet or marine surroundings. That
combination keeps it in bushings, bearings and seawater-exposed hardware.
Machinable Forms
Bar, plate, casting, tube
Surface Finish Options
Polishing, plating, natural patina
CNC Machining Advantages
Good wear resistance, low friction, corrosion resistant
Typical Applications

4–7 business days
Supported CNC Services
CNC milling, CNC turning, drilling
Tolerance Capability
±0.01 mm for standard machining
Steel CNC Machining
Carbon steel remains the workhorse where load, shock and cost all matter at once.
It takes structural sections, tooling bodies and stressed brackets in its stride,
and it responds predictably to heat treatment and coating afterwards.
Machinable Forms
Plate, bar, tube, forging
Surface Finish Options
Black oxide, plating, powder coating, painting
CNC Machining Advantages
High strength, good wear resistance, versatile applications
Typical Applications

5–8 business days
Supported CNC Services
CNC milling, CNC turning, drilling, threading
Tolerance Capability
±0.01 mm with proper setup
When a part has to survive moisture, washdown chemicals and years of service without
a coating to hide behind, stainless is the specification. It machines tougher than
aluminum and demands rigid setups and disciplined coolant, but it delivers strength
and corrosion resistance in the same piece of metal.
Machinable Forms
Bar, plate, tube
Surface Finish Options
Polishing, passivation, brushing, electropolishing
CNC Machining Advantages
High strength, corrosion resistance, wear resistance
Typical Applications
Medical devices, food equipment, marine components

Lead Time
5–8 business days
Supported CNC Services
CNC milling, CNC turning, threading
Tolerance Capability
±0.01 mm achievable on precision parts
Alloy Steel CNC Machining
Adding chromium, nickel or molybdenum to steel shifts its behaviour on purpose:
more hardenability, more toughness, better fatigue life under cycling load. Gears,
shafts and high-strength fasteners are the natural home for it, usually paired with
heat treatment after machining.
Machinable Forms
Bar, plate, forging, billet
Surface Finish Options
Heat treatment, plating, black oxide, grinding
CNC Machining Advantages
High strength and hardness, good fatigue resistance
Typical Applications
Gears, shafts, high-strength fasteners, automotive components
Available Grades
4340, 8620, 4130, 4140
Lead Time
6–9 business days
Supported CNC Services
CNC milling, CNC turning, heat treatment, grinding
Tolerance Capability
±0.01 mm achievable with post-machining treatments
Magnesium CNC Machining
Magnesium is the lightest structural metal you can put on a machine, which makes it
the choice when every gram is being counted — aerospace brackets, handheld
housings, motorsport parts. It cuts freely and fast; the discipline it demands is in
chip handling and fire-safe practice, not in the cutting itself.
Machinable Forms
Plate, bar, casting
Surface Finish Options
Anodizing, painting, plating, chemical treatment
CNC Machining Advantages
Extremely lightweight, good strength-to-weight ratio, excellent machinability
Typical Applications
Aerospace components, automotive parts, electronics enclosures

AZ31B, AZ91D, AM60B
Lead Time
4–7 business days
Supported CNC Services
CNC milling, CNC turning, drilling
Tolerance Capability
±0.02 mm with careful handling
Brass CNC Machining
Brass is the easiest copper alloy to machine and one of the few materials that looks
finished the moment it leaves the spindle. Valves, fittings and instrument-grade
hardware use it for exactly that reason: predictable cutting plus an appearance
worth polishing rather than covering.
Machinable Forms
Rod, plate, tube, casting
Surface Finish Options
Polishing, plating, lacquering, natural finish
CNC Machining Advantages
Excellent machinability, good corrosion resistance, attractive appearance
Typical Applications
Valves, fittings, decorative hardware, musical instruments
Available Grades
C360, C260, C464, C385
Lead Time
3–6 business days
Supported CNC Services
CNC milling, CNC turning, drilling, tapping
Tolerance Capability
±0.01 mm for standard features
ABS CNC Machining
ABS is inexpensive, forgiving on impact and dimensionally steady, which makes it the
sensible first pass for enclosures and functional plastic parts. It machines quickly
and can be sanded, painted or textured to stand in for a moulded production part.
Machinable Forms
Sheet, rod, block
Surface Finish Options
Polishing, painting, texturing
CNC Machining Advantages
Easy machining, low cost, stable dimensions
Typical Applications
Housings, enclosures, prototypes
Available Grades
General ABS, flame-retardant ABS
Lead Time
2–4 business days
Supported CNC Services
CNC milling, CNC turning
Tolerance Capability
±0.02 mm depending on geometry
Nylon (PA) CNC Machining
Nylon brings strength, abrasion resistance and a low-friction surface to parts that
rub, roll or slide — gears, bushings, rollers. It does absorb moisture and moves
slightly as it does, so we plan for that in the tolerance stack instead of pretending
it is not happening.
Machinable Forms
Sheet, rod, tube, block
Surface Finish Options
Polishing, dyeing, tumbling
CNC Machining Advantages
High strength, good wear resistance, low friction
Typical Applications
Gears, bushings, rollers, insulators
Available Grades
PA6, PA66, PA12, glass-filled nylon
Lead Time
3–5 business days
Supported CNC Services
CNC milling, CNC turning, drilling
Tolerance Capability
±0.02 mm depending on moisture content
Polycarbonate (PC) CNC Machining
Polycarbonate gives you a see-through part that refuses to shatter. Guards, lenses
and light covers use it where glass would be fragile and acrylic too brittle, and
because it is machinable rather than moulded, single units stay economic.
Machinable Forms
Sheet, rod, block, tube
Surface Finish Options
Polishing, flame polishing, anti-scratch coating
CNC Machining Advantages
High impact resistance, optical clarity, good dimensional stability
Typical Applications
Protective shields, lenses, light covers, medical devices
Available Grades
General purpose, UV resistant, flame retardant
Lead Time
3–6 business days
Supported CNC Services
CNC milling, CNC turning, drilling, engraving
Tolerance Capability
±0.02 mm for clear parts
PEEK CNC Machining
PEEK holds its shape and its mechanical strength where ordinary plastics would fail
— high temperature, aggressive chemistry, repeated sterilisation. That puts it
in aerospace, implant and semiconductor hardware, and it prices accordingly, so
nesting and tool-path efficiency directly affect what your part costs.
Machinable Forms
Rod, plate, tube, film
Surface Finish Options
Polishing, as-machined, coating
CNC Machining Advantages
High temperature resistance, excellent chemical resistance, high strength
Typical Applications
Aerospace components, medical implants, semiconductor parts

Unfilled, carbon-filled, glass-filled
Lead Time
5–10 business days
Supported CNC Services
CNC milling, CNC turning, precision machining
Tolerance Capability
±0.01 mm achievable for critical dimensions
PTFE CNC Machining
PTFE is chemically inert and almost frictionless, which is exactly what seals,
gaskets and lab hardware need. It is also soft and prone to creeping under load, so
we cut it with light passes and design clearance for the material's movement rather
than against it.
Machinable Forms
Sheet, rod, tube, film
Surface Finish Options
As-machined, skiving, etching
CNC Machining Advantages
Excellent chemical resistance, very low friction, high temperature stability
Typical Applications
Seals, gaskets, insulators, laboratory equipment
Available Grades
Virgin PTFE, filled PTFE (glass, carbon, bronze)
Lead Time
4–8 business days
Supported CNC Services
CNC milling, CNC turning, skiving, stamping
Tolerance Capability
±0.02 mm due to material flexibility
POM CNC Machining
POM — acetal, or Delrin on most drawings — is the engineer's plastic for
precision moving parts. It holds tolerance far better than most polymers, slides
against metal without lubricant, and machines cleanly enough to be tapped, bored and
finished in one setup.
Machinable Forms
Rod, plate, tube, block
Surface Finish Options
Polishing, tumbling, as-machined
CNC Machining Advantages
Low friction, excellent dimensional stability, good wear resistance
Typical Applications
Gears, bearings, rollers, precision parts

3–5 business days
Supported CNC Services
CNC milling, CNC turning, drilling
Tolerance Capability
±0.01 mm for stable geometries
PMMA CNC Machining
PMMA, sold as acrylic, gives you glass-like clarity with a fraction of the weight and
far better weathering. Signs, display parts and protective barriers use it because it
machines and polishes to a genuinely transparent edge, indoors or out.
Machinable Forms
Sheet, rod, tube, block
Surface Finish Options
Polishing, flame polishing, coating
CNC Machining Advantages
Excellent optical clarity, good weather resistance, easy to machine
