Lightweight Metals for CNC milling

Aluminum Alloys

Overview

Aluminum combines low density, good strength, thermal conductivity, and excellent cutting performance. It is a dependable first choice for fast-turn prototypes and production parts that need a strong strength-to-weight ratio.

Key Advantages

  • Fast machining and short cycle times
  • Good dimensional stability in common aerospace and industrial grades
  • Broad anodizing and cosmetic finish options

Material properties and achievable tolerances vary by grade, condition, geometry, part size, and inspection method. Final recommendations are confirmed during engineering review.

Tolerances for CNC Milling

Our CNC milling process is planned around drawing requirements, GD&T notes, material stability, and final inspection needs.

General TolerancesMetals: ISO 2768-m
Plastics: ISO 2768-c
Precision TolerancesStrict features can be controlled to ±0.005mm depending on geometry, material, and inspection method.
Min Wall Thickness0.5mm recommended for most milled metal parts
Min End Mill Size0.5mm
Min Drill Size1mm
Maximum Part SizeCNC milling reference envelope: 4000 x 1500 x 600mm
Minimum Part Size5 x 5mm depending on fixturing and part geometry
