Start with requirements
Good material selection starts with the job the part must do. Instead of choosing a familiar material by name, define the environment, load, movement, temperature, chemicals, outdoor exposure, electrical needs, food or skin contact, color, and expected production quantity.
Material families
| Family | Examples | Typical use |
|---|---|---|
| Aluminum | 6061, 6082, 7075, sheet alloys | Lightweight metal parts, prototypes, brackets, housings, and finished components. |
| Steel | Mild steel, alloy steel, tool steel | Strength, structure, wear, weldability, and cost-effective metal parts. |
| Stainless steel | 304, 316 | Corrosion resistance, clean appearance, food-like environments where suitable. |
| Engineering plastics | POM, PA, PC, ABS, PEEK | Low friction, insulation, light weight, chemical or heat performance. |
| Printed polymers | PLA, PETG, ASA, nylon, resin | Prototypes, fixtures, visual models, and low-volume parts. |
| Elastomers and urethanes | TPU, silicone, cast urethane | Flexible seals, grips, vibration, soft-touch features. |
Selection questions
- Will the part carry load, impact, vibration, pressure, or wear?
- Will it be exposed to heat, UV, humidity, salt, chemicals, oil, or cleaning agents?
- Does it need to be light, rigid, flexible, transparent, electrically insulating, or conductive?
- Does the part need cosmetic finish, color, texture, or corrosion protection?
- Is this a prototype, pilot batch, or repeat production part?
Process compatibility
| Process | Material logic | Important tradeoff |
|---|---|---|
| CNC | Real engineering metals and plastics from stock | Strong material properties but higher cost for complex geometry. |
| 3D printing | Material depends heavily on print technology | Fast complex shapes but different properties from billet or molded material. |
| Sheet metal | Sheet alloy and thickness define bending and cutting behavior | Efficient for panels and brackets but limited to formed sheet geometry. |
| Molding | Production material must be stable before tooling | Low unit cost at volume but tooling changes are expensive. |
| Finishing | Base material controls available finish | Some finishes alter dimensions, color, or surface behavior. |
Cost and availability
Standard materials are usually faster and cheaper than special grades. Rare alloys, certified batches, high-performance plastics, special colors, or supplier-specific grades may require manual review and longer lead time.
Uretyco AI workflow
- 1Describe performance
Tell the assistant what the part must resist or achieve.
- 2Compare materials
Review strength, heat, corrosion, weight, finish, cost, and lead-time tradeoffs.
- 3Validate process fit
Check whether the selected material is compatible with the chosen process and finish.
- 4Confirm on order
Lock material grade and any certificate needs before production.
FAQ
- Can Uretyco choose the material for me? It can recommend options, but final suitability should be confirmed for critical applications.
- Can I request a material certificate? Yes, when available and included in the order scope.
- Can I switch material after quoting? Material changes can change price, lead time, supplier match, and manufacturability.
