Metal Materials for Custom Parts
Machined Parts Pro supports common metal materials for custom CNC machined parts, sheet metal parts, metal hardware, brackets, enclosures, panels, and decorative metal products.
Material Selection
Choosing the Right Material for Custom Metal Parts
Material selection affects strength, weight, corrosion resistance, machinability, appearance, surface finish, and production cost. For custom metal parts, the best material is not always the strongest or most expensive one. It should match the product function, working environment, production method, and budget.
This page introduces common materials used for CNC machining, sheet metal fabrication, metal hardware, brackets, enclosures, panels, and decorative metal products. Customers can use it as a basic reference before sending drawings, samples, or product ideas for quotation.

- Lightweight precision components
- Corrosion-resistant parts
- Special machined metal products
Selection Guide
How to Choose a Suitable Metal Material
If you are not sure which material is suitable, you can start from the part function, working environment, strength requirement, appearance requirement, and target cost.
For Lightweight Parts
Aluminum is often a practical choice for lightweight housings, fixtures, panels, brackets, and CNC machined components.
For Corrosion Resistance
Stainless steel, aluminum, and titanium can be considered depending on the environment and surface finish requirements.
For Structural Strength
Carbon steel and stainless steel are commonly used for frames, brackets, supports, mounting parts, and welded structures.
For Appearance Parts
Aluminum, stainless steel, brass, and copper are often selected for visible parts, decorative products, nameplates, and display items.
Process Compatibility
Materials Matched with Manufacturing Processes
Different manufacturing methods work better with different materials. The final choice should consider both product design and production process.
CNC Machining
Aluminum, stainless steel, brass, copper, titanium, and selected steels can be used for CNC machined parts depending on tolerance, surface finish, and part complexity.
Sheet Metal Fabrication
Stainless steel, carbon steel, aluminum, and galvanized steel are commonly used for sheet metal brackets, enclosures, panels, covers, and chassis.
Decorative Metal Products
Stainless steel, aluminum, brass, and copper are commonly used for decorative metal signs, panels, nameplates, display stands, and commercial metal crafts.
Surface Finishes
Finishing Options for Custom Metal Parts
Surface finishing can improve corrosion resistance, wear resistance, appearance, touch feeling, branding effect, and product value.
