While aluminum alloys rely heavily on Hoʻonui nui, stainless steels employ various heat-treatment routes—Annalile, Queech, A a me ka wā kamaliʻi—to adjust hardness and toughness.

Native Oxide Layer Characteristics

'Ainuiʻo ALXIE PAUL (Al₂o₃)

• Immediately upon exposure to air, ʻO ka Aluminim e hana i kahi lahilahi (~ 2–5 nm) adherent oxide film.
  This passive film protects the underlying metal from further oxidation in most environments.
  Akā naʻe,, in strongly alkaline solutions (ph > 9) or halide‐rich acid, the film dissolves, exposing fresh metal.
  Anodizing artificially thickens the Al₂O₃ layer (5-25 μM), greatly enhancing wear and corrosion resistance.

Chromium Oxide (Cr₂o₃)

• Stainless steels rely on a protective Cr₂O₃ layer. Even with minimal chromium content (10.5 %), this passive film impedes further oxidation and corrosion.
  In chloride‐rich environments (E.g., Ke wai wai, salt spray), localized breakdown (pitting) can occur;
  molybdenum additions (E.g., 316 Kumu, 2-3 % Mo) improve resistance to pitting and crevice corrosion.

Atmospheric and Marine Environments

• Aluminum (E.g., 6061, 5083, 5xxx series) performs well in marine settings when properly anodized or with protective coatings;
  Akā naʻe,, crevice corrosion can initiate under deposits of salt and moisture.
• Kila kohu ʻole (E.g., 304, 316, Duplex) excels in marine atmospheres. 316 (Mo‐alloyed) and super‐duplex are particularly resistant to pitting in seawater.
  Nā helu Ferritic (E.g., 430) have moderate resistance but can suffer rapid corrosion in salt spray.

Chemical and Industrial Exposures

• Aluminum E kū i nā lāʻau lapaʻau hoʻonohonoho (Acetic, formic) but is attacked by strong alkalis (Naoh) and halide acids (HCOL, HBr).
  In sulfuric and phosphoric acids, certain aluminum alloys (E.g., 3003, 6061) can be susceptible unless concentration and temperature are tightly controlled.
• Kila kohu ʻole exhibits broad chemical resistance. 304 resists nitric acid, organic acids, a me ka alkalis alkalis; 316 endures chlorides and brines.
  Duplex stainless steels withstand acids (lupulakai, phoshparic) better than austenitic alloys.
  ʻO nā māka martestitic (E.g., 410, 420) are prone to corrosion in acid environments unless heavily alloyed.

  Maā ~ 600 ° C, rapid growth of oxide scales and potential intergranular oxidation occurs.
• Kila kohu ʻole: Austenitic grades maintain oxidation resistance up to 900 ° C.
  For cyclic oxidation, specialized alloys (E.g., 310, 316Huh, 347) with higher Cr and Ni resist scale spallation.
  Ferritic grades form a continuous scale up to ~ 800 °C but suffer embrittlement above 500 °C unless stabilized.

Machinability and Cutting Characteristics

Aluminum (E.g., 6061-T6, 7075-T6)

• Chip Formation and Tooling: Aluminum produces short, curled chips that dissipate heat efficiently.
  Its relatively low hardness and high thermal conductivity draw cutting heat into the chips rather than the tool, ho'ēmi i ka lole lole.
  Carbide tools with TiN, Gula, or TiCN coatings at cutting speeds of 250–450 m/min and feeds of 0.1–0.3 mm/rev yield excellent surface finishes (Ra 0.2–0.4 µm).
• Kūkulu i luna (Ke kakaka): Because aluminum tends to adhere to tool surfaces, controlling BUE requires sharp tool edges, moderately high feed rates, and flood coolant to wash away chips.
• Tolerance and Surface Finish: Nā mea paʻa paʻa (± 0.01 mm on critical features) are achievable with standard CNC setups.
  Surface finishes down to Ra 0.1 µm are possible when using high-precision fixtures and carbide or diamond-coated tooling.
• Hana-paʻakikī: Minina; downstream passes can maintain consistent material properties without intermediate annealing.

Kila kohu ʻole (E.g., 304, 17-4 Ph)

• Chip Formation and Tooling: Austenitic stainless steels work-harden rapidly at the cutting edge.
  Slow feed rates (50–150 m/min) combined with positive-rake, cobalt-cermet, or coated carbide tools (TiAlN or CVD coatings) help mitigate work-hardening.
  Ramped down leads, peck drilling, and frequent tool retraction minimize chip welding.
• Built-Up Edge and Heat: Low thermal conductivity confines heat to the cutting zone, Hoʻokomoʻia ka mea hana hana.
  High-pressure flood coolant and ceramic-insulated tool bodies extend cutter life.
• Tolerance and Surface Finish: Dimensions can be held to ± 0.02 mm on medium-duty lathes or mills; specialized tooling and vibration damping are required for finishes below Ra 0.4 }m.
• Hana-paʻakikī: Frequent light cuts reduce the hardened layer; once work-hardened,
  further passes require decreased feed or a return to annealing if hardness exceeds 30 Hrc.

Cost is a critical factor in material selection, encompassing not only initial purchase price but also long-term expenses such as fabrication, mālama, a me ka pau-o-ola-ola.

Upfront Material Cost:

• Aluminum’s raw material price (~ $2,200–$2,500/ton) is generally lower than most stainless grades (E.g., 304 at $2,500–$3,000/ton).
• Stainless steel alloys with higher nickel and molybdenum content can exceed $4,000–$6,000/ton.

Fabrication Cost:

• Aluminum fabrication is typically 20-40 % less expensive than stainless steel due to easier machining, lower welding complexity, and lighter forming loads.
• Stainless steel’s higher fabrication costs stem from tool wear, Ke hoʻololi nei i nā wikiwiki, and more stringent welding/passing requirements.

Maintenance and Replacement:

• Aluminum may incur periodic recoating or anodizing costs (estimated $15–$25/kg over 20 makahiki), whereas stainless steel often remains maintenance-free (≈ $3–$5/kg).
• Frequent part replacements for fatigue or corrosion can elevate aluminum’s lifecycle cost, whereas stainless steel’s longevity can justify higher initial investment.

Energy Consumption and Sustainability:

• Primary aluminum production consumes ~ 14–16 kWh/kg; stainless steel EAF routes range from ~ 1.5–2 kWh/kg, making recycled stainless less energy-intensive than primary aluminum.
• High recycled content in aluminum (≥ 70 %) reduces energy to ~ 4–5 kWh/kg, narrowing the gap.
• Both materials support robust recycling loops—aluminum recycling reuses 95 % ka nui o ka ikehu, stainless EAF uses ~ 60 % less energy than BF-BOF.

Recycling Value:

• End-of-life aluminum recovers ~ 50 % of initial cost; stainless steel scrap returns ~ 30 % of initial cost. Market fluctuations can affect these percentages, but both metals retain significant scrap value.
