The workhorse of aluminum alloys. Excellent strength-to-weight ratio, good corrosion resistance, and outstanding machinability. The first choice for most structural and general-purpose parts.

Common uses: Brackets, housings, structural frames, enclosures, drone components

High-strength aerospace-grade aluminum. Near the strength of steel at one-third the weight. Less corrosion-resistant than 6061 but the top choice when strength is paramount.

Common uses: Aircraft structures, missile components, high-stress brackets, sporting goods

Excellent fatigue resistance with high strength. Standard for aircraft skins and structures where cyclic loading is a primary concern. Poor weldability — mechanical fastening preferred.

Common uses: Aircraft skins, fuselage frames, wing tension members

The premier sheet metal aluminum. Superior corrosion resistance (especially in marine environments), excellent formability, and good weldability. Not heat-treatable.

Common uses: Marine panels, fuel tanks, enclosures, sheet metal assemblies

Low-carbon steel with outstanding weldability and excellent machinability. The go-to for parts that don't require high hardness or tensile strength. Highly cost-effective.

Common uses: Shafts, pins, keys, fixtures, welded assemblies

Chromium-molybdenum alloy steel with high toughness, strength, and fatigue resistance. Can be heat-treated to a wide range of hardness values. The standard for shafts and tooling.

Common uses: Shafts, gears, spindles, tooling, high-load fasteners

The most machinable austenitic stainless steel. Sulfur addition dramatically improves chip breaking. Good corrosion resistance — not suitable for saltwater or highly chlorinated environments.

Common uses: Bolts, nuts, shafts, fittings, food-contact parts

Molybdenum-enhanced austenitic stainless with superior corrosion resistance, including chlorides and seawater. The standard for marine, medical, and chemical processing applications.

Common uses: Marine hardware, medical implants, chemical tanks, food processing

Precipitation-hardened martensitic stainless. Combines the corrosion resistance of 304 with yield strength approaching alloy steel. Available in multiple H-conditions for tailored properties.

Common uses: Aerospace fasteners, pump shafts, nuclear components, surgical instruments

The most widely used titanium alloy. Exceptional strength-to-weight ratio, excellent biocompatibility, and corrosion resistance in virtually all environments. Requires careful tooling and cutting parameters.

Common uses: Aerospace structures, orthopedic implants, marine hardware, high-performance motorsport

Nickel-chromium superalloy with outstanding resistance to oxidation, corrosion, and high temperatures up to 1800°F. Notoriously difficult to machine — experienced toolpaths and sharp inserts are mandatory.

Common uses: Jet engine components, chemical processing, seawater equipment, nuclear reactors

Acetal homopolymer with the best machinability of any engineering plastic. Low friction, high stiffness, excellent dimensional stability, and moisture resistance. The default for precision plastic parts.

Common uses: Gears, bushings, bearings, valve seats, food-contact components

High-performance semi-crystalline thermoplastic with excellent mechanical properties retained up to 480°F. Chemical resistance rivals PTFE. The premium choice when metal is not an option.

Common uses: Medical implants, aerospace brackets, semiconductor equipment, pump components

Versatile polyamide with good toughness, wear resistance, and self-lubricating properties. Absorbs moisture which can affect dimensions — dry storage and moisture sealing recommended for tight tolerances.

Common uses: Gears, bushings, cable ties, structural brackets, wear pads

Exceptional impact resistance — nearly unbreakable at room temperature. Optically clear grades available. Susceptible to some solvents and UV degradation without stabilizers.

Common uses: Safety shields, lenses, electronics housings, light covers, medical devices

Ultra-high-molecular-weight polyethylene. Exceptional abrasion resistance, very low coefficient of friction, and chemical resistance. Soft and self-damping. Cannot be injection molded — CNC only.

Common uses: Wear liners, guides, conveyor components, cutting boards, marine dock bumpers

The most common engineering plastic. Good impact resistance, easy to machine, paint, and bond. Acetone smoothing works on 3D-printed ABS. Not suited for outdoor UV exposure without UV-stabilized grades.

Common uses: Consumer electronics housings, automotive interiors, prototypes, enclosures

Free-machining brass — the highest machinability rating of any metal at 100% on the standard scale. Excellent electrical conductivity, good corrosion resistance, and attractive appearance.

Common uses: Fittings, valves, connectors, terminals, precision fasteners

Electrolytic tough pitch copper with 99.9% purity and 101% IACS electrical conductivity. The standard for electrical bus bars, conductors, and heat exchangers requiring maximum conductivity.

Common uses: Bus bars, heat sinks, electrical contacts, RF shielding, heat exchangers
