Common Material Groups

Group Primary Materials Key Characteristics
Aluminum 6061-T6, 7075-T6 High strength-to-weight, excellent machinability, anodizable.
Stainless Steel 303, 304, 316L Corrosion resistance, high strength, food/medical safe.
Alloy Steel 1018, 4140 High hardness, tough, good for gears and shafts.
Other Metals Brass C360, Titanium Gr5 Conductivity (Brass) or Extreme Strength (Titanium).
Plastics POM (Delrin), ABS, PEEK Lightweight, insulating, low friction.
Pro Tip: Aluminum 6061-T6 is the "standard" CNC material. If your part doesn't require specific thermal, chemical, or extreme mechanical properties, 6061 is almost always the most cost-effective choice.
