Common Material Types Metallic Materials: Aluminum alloys (such as 6061/7075), stainless steels (304/316), copper alloys, titanium alloys, carbon steels, etc. Engineering Plastics: ABS, Nylon (PA), Polyoxymethylene (POM), Acrylic (PMMA), Polycarbonate (PC), Polyetheretherketone (PEEK), etc. Composite Materials: Glass fiber reinforced plastics, carbon fiber composite materials, etc. For the processing of special materials, it is necessary to communicate the material specification sheets (such as AMS and ASTM standards) in advance. For some materials, customized cutting tools are required or the processing parameters need to be adjusted.
