Technical Profile

Material Grade & Property Comparison

Reference values for engineering properties, thickness impacts, and environmental resistance.

Material Grade Strength Level Service Temperature Corrosion & Wear Finish Compatibility
C360 Brass Medium, tensile 330 MPa Max 250°C Good resistance to organic chemicals Nickel plating, lacquer
C110 Copper Medium, tensile 220 MPa Max 150°C Moderate; tarnishes in open air Electroless nickel, tin plating

Best-Fit Manufacturing Processes

Best Fit Precision CNC Milling

The standard route for complex 3D profiles, gear housings, brackets, and flat base plates.

Best Fit Precision CNC Turning

Highly concentric circular shapes, threaded studs, precision shafts, and connector collars.

Highly Compatible Sheet Metal Bending

Excellent for formable metal grades such as Alu 5052 and SS304.

Post Processing

Surface Finish Compatibility

Common post-machining surface treatments compatible with this material class.

As Machined

Parts are deburred. Machining marks remain visible and dimensional precision is preserved.

Roughness: Ra 1.6 - 3.2 µm Cost: Baseline

Bead Blasting

Fine glass beads create a uniform matte satin texture and hide machining marks.

Roughness: Ra 0.8 - 1.6 µm Cost: Low

Anodizing

Electrochemical oxide coating for corrosion protection, color options, or hardcoat wear resistance.

Thickness: 5-50 µm Aesthetic: Matte/Semi-gloss

Chemical Conversion / Plating

Chem-film and electroless nickel add corrosion or wear protection with controlled buildup.

Thickness: 1-20 µm Standard: MIL-spec options
Engineering Checklist

Procurement & Purchasing Notes

Key technical points to address on drawings to ensure immediate manufacturing alignment.

Area of Review Engineering Guidelines Why it Matters / Notes
Material Traceability Raw material certification (MTR) checked against alloy composition profiles. Confirms the raw stock grade before machining starts. Available upon request.
Drawing Controls Toleranced dimensions checked on 2D PDF drawings. Standard machining tolerance applies to unmarked features; critical tolerances must be highlighted.
Coating Allowance Layer thickness buildup for anodizing, plating or powder coating is evaluated. Specify whether drawing dimensions apply before or after coating to avoid interference.
Questions

Material FAQ

What metal grades are best for outdoor or marine use?

Stainless steel 316 or anodized aluminum 6061/7075 offer strong corrosion protection.

Can you provide material certificates?

Yes. Material test reports can be provided upon request before production.

How do I call out tight tolerances?

Mark key tolerances on a 2D PDF drawing while keeping non-critical features to standard tolerance.
