From 6061 aluminum prototypes to 17-4 PH stainless production runs — matched tooling, feeds, and inspection for every alloy we cut.
Material selection drives almost every downstream decision in a machining program — tool geometry, surface speed, chip evacuation, coolant choice, work-holding strategy, and final finish all flow from the alloy on the bar. Our production network routinely runs aluminum alloys, stainless steels, carbon and alloy steels, brass, bronze, copper, and a range of engineering plastics across 5-axis milling, CNC turning, and Swiss-type platforms. Titanium and high-nickel alloys are available on request to suit program-specific material specifications. The pages below describe how each material family is approached: the grades seen most often, the applications they fit, the tolerances and finishes that come out of the spindle, and the secondary operations that round the part out.
6061, 7075, 2024, 5052 and other wrought alloys for aerospace brackets, housings, fixturing, and weight-critical components.
303, 304, 316, and 17-4 PH for medical, marine, food, and aerospace work that has to resist corrosion and hold its dimensions.
1018, 1215, 4140, 4340, A36 and similar for shafts, fittings, and structural components, with heat-treat coordinated as needed.
C360 free-machining brass and C110 copper for fittings, electrical contacts, fluid components, and conductive hardware.
Delrin/acetal, PEEK, UHMW, polycarbonate, and PTFE for insulators, fluid-handling parts, and weight-sensitive prototypes.
Ti-6Al-4V (Grade 5) and Grade 2 commercially pure for aerospace and medical work — available on request for spec'd programs.
The general-purpose workhorse — weldable, anodizable, predictable.
Aircraft-grade strength approaching mild steel at a third of the weight.
The fatigue-critical airframe alloy of legacy MIL drawings.
Free-machining stainless — the natural choice for Swiss-turned parts.
The general-purpose corrosion-resistant grade for food, medical, and industrial work.
Molybdenum-bearing chloride resistance for marine and medical parts.
Precipitation-hardening strength — machine in Condition A, then age.
Chromoly for shafts, fixtures, and tooling — pre-hard or heat-treated.
Grade 5 titanium machined with proper heat management.
The 100%-machinability reference metal for fittings and turned parts.
High-performance polymer for semiconductor, medical, and downhole parts.
The easiest precision plastic — bushings, gears, and insulators.
Flame-smoke-toxicity rated for aircraft interiors and dielectric parts.
Every order quotes a specific alloy, temper, and form — bar diameter, plate thickness, or near-net stock as the print calls for. Material certifications and lot traceability are standard on government and aerospace programs, and we keep mill paperwork on file with the job traveler so it ships with the parts. If your drawing specifies an alternate or substitute, we will flag it during drawing review rather than assume.
