Choosing Between Stainless Steel, Aluminum, Copper, and Brass?
| Metal | Pros | Cons | Common Uses |
|---|---|---|---|
| Stainless Steel | High strength, corrosion resistant | Heavy, harder to form | Outdoor, medical, kitchen tools |
| Aluminum | Lightweight, rust-proof, easy to shape | Less strong, alloy cost varies | Automotive, aerospace, electronics |
| Copper | Conductive, antimicrobial, easy to stamp | Soft, low wear strength | Electrical contacts, cooling systems |
| Brass | Decorative, corrosion-resistant, formable | Prone to dezincification in water | Plumbing, appliances, art panels |

Mechanical Properties That Matter Most in Stamped Components?
| Property | Stainless Steel 304 | Aluminum 6061‑T6 | Copper C110 | Brass C260 |
|---|---|---|---|---|
| Yield Strength (MPa) | 215–275 | 276 | \~70 | 200–250 |
| Tensile Strength | 505 | 310 | \~210 | 300–360 |
| Elongation (%) | 40–60 | 12–18 | 30–50 | 20–40 |
| Hardness (HV) | \~170 | \~95 | \~60 | 80–180 |
| Fatigue Strength | High | Medium | Low | Medium |
Stainless works for harsh loads. Aluminum cuts weight. Copper offers conductivity. Brass provides elegant formability.
How Material Selection Affects Tool Life and Cost?
| Metal | Tool Wear Rate | Lubrication Needed | Sharpening Frequency | Downtime Cost |
|---|---|---|---|---|
| Stainless Steel | High | High | Every 10k–20k strokes | High |
| Aluminum | Medium | Medium | Every 30k+ strokes | Low |
| Copper | Low | Low | Rarely | Very Low |
| Brass | Medium | Low | Every 40k strokes | Low |
| Material | Avg Cost/kg (USD) | Notable Cost Drivers |
|---|---|---|
| Stainless Steel | \$1.50–2.50 | Alloy content, global demand |
| Aluminum 6061 | \$2.00–3.00 | Alloying, shipping, machining difficulty |
| Copper | \$9.50–11.60 | Electronics demand, purity |
| Brass | \$5.00–7.00 | Zinc content, polishing, finishes |
