Materials We Machine

Aluminum Alloys

Aluminum is our most commonly machined material. Light, excellent machinability, and takes anodizing well. The grade matters significantly for strength and application.

Grade	Tensile Strength	Typical Use	Machinability	Anodizing
6061-T6	310 MPa	General structural, brackets, housings	Excellent	Excellent
7075-T6	572 MPa	Motorsport, aerospace, high-load parts	Good	Good
2024-T3	483 MPa	Aircraft structure, fatigue-critical	Good	Fair
5052-H32	228 MPa	Marine, sheet-form parts	Good	Excellent
6063-T5	186 MPa	Extrusions, decorative finish	Excellent	Excellent

Stainless Steel

Stainless steel for corrosion resistance in demanding environments. Grade selection depends on the specific corrosive agent and mechanical requirements.

Grade	Tensile Strength	Typical Use	Notes
304	515 MPa	General corrosion resistance, food equipment	Most common austenitic grade
316L	485 MPa	Food contact, medical, chloride environments	Molybdenum added for chloride resistance
303	620 MPa	High-volume turned parts	Free-machining, not for welding
17-4PH	1170 MPa	High strength + corrosion resistance	Precipitation hardened, aerospace
420	690 MPa	Cutlery, medical instruments, hardened	Martensitic, heat-treatable

Brass & Copper Alloys

Grade	Common Name	Typical Use	Notes
C36000 (CuZn39Pb3)	Free-machining brass	Fittings, valves, connectors	Machinability 100% — industry benchmark
C26000 (CuZn30)	Cartridge brass	Precision turned parts, no lead	Lead-free, food/water safe
C11000	Pure copper (ETP)	Electrical, heat transfer	High conductivity, soft
C17200	Beryllium copper	Springs, connectors, non-sparking tools	High strength + conductivity

Steel & Tool Steel

Grade	Tensile Strength	Typical Use	Heat Treatment
1018	440 MPa	General structural, shafts	Carburizing only
1045	570 MPa	Gears, shafts, crankshafts	Good hardenability
4140	655–1000 MPa	High-stress structural, tooling	Through-hardening
4340	745–1170 MPa	Aerospace, high-strength shafts	High hardenability
D2 Tool Steel	—	Dies, punches, cutting tools	Air-hardening

Titanium

Titanium is 45% lighter than steel with comparable strength. We machine Grade 2 (commercially pure, corrosion resistant) and Grade 5 / Ti-6Al-4V (the aerospace workhorse — highest strength-to-weight ratio).

Titanium machining requires slower speeds, sharp tools, and coolant — our engineers specify the correct cutting parameters to avoid work-hardening and built-up edge. We have machined titanium parts for medical, aerospace, and motorsport customers.

Engineering Plastics

We machine PEEK, Delrin (POM), Nylon (PA6/PA66), PTFE, polycarbonate, and UHMWPE for applications requiring chemical resistance, low weight, or electrical insulation. Call out the plastic grade on your drawing — we do not substitute.
