What Buyers Should Confirm
| Base material | Material grade, hardness condition, thickness or billet size, and any required certificate or standard. |
|---|---|
| Finish target | Color, texture, gloss, corrosion resistance, wear resistance, masking areas, and cosmetic acceptance level. |
| Part function | Visible surface, sliding surface, threaded holes, sealing area, electrical contact, assembly contact, or welding area. |
| Drawing files | STEP, STP, IGS, PDF, DWG, DXF, STL, sample photo, or previous production reference. |
Common Materials
Aluminum 6061 / 7075
Lightweight CNC parts, brackets, housings, drone parts, knobs, and anodized hardware.
Stainless Steel 304 / 316
Corrosion-resistant shafts, fittings, precision hardware, and visible components.
Carbon Steel
Strong brackets, plates, welded frames, formed parts, and painted structures.
Brass / Copper
Conductive parts, inserts, bushings, fittings, and decorative turned components.
Titanium
High strength-to-weight machined parts for demanding applications.
POM / PEEK / Nylon
Insulating, lightweight, low-friction, or wear-resistant non-metal parts.
Copper Alloy
Conductive and corrosion-resistant alloy parts can be reviewed by drawing.
Project-Specified Metals
Other materials can be reviewed with drawings, standards, or samples.
Surface Finish Options
CNC Machined
Natural machined surface with visible machining pattern and controlled dimensions.
Sand Blasting
Matte texture for visual consistency, grip, or pre-treatment before coating.
Anodizing
Common for aluminum parts that need color, corrosion resistance, and cleaner appearance.
Hard Anodizing
Used when aluminum parts need improved wear resistance and more durable surfaces.
Polishing
Improves smoothness and visible appearance for customer-facing metal components.
Brushing
Creates a satin linear texture for decorative panels, covers, housings, and hardware.
Electroplating
Chrome, nickel, zinc, or other plating depending on material, appearance, and corrosion requirement.
Powder Coating
Durable color coating for sheet metal, frames, brackets, and protective product housings.
How We Match Finish to Use
RFQ Checklist
- Drawing or CAD file with material, tolerance, and surface finish notes.
- Target quantity, sample requirement, expected application, and visible surface standard.
- Finish sample, color reference, product photo, or previous supplier requirement if available.
