| SS400 | Structural steel | Low cost, easy to weld, not hardenable | Frames, structures and non-critical parts |
| S45C | Carbon steel | Suitable for quench-and-temper treatment, moderate strength, widely used | Shafts, gears and load-bearing machine parts |
| SCM440 | Cr–Mo alloy steel | Deep hardening and high strength | Heavy-duty shafts and high-strength bolts |
| SKD11 | Cold-work tool steel | Hard, wear-resistant and dimensionally stable after heat treatment | Stamping dies, punches, dies and cutting tools |
| SKD61 | Hot-work tool steel | Good resistance to thermal shock | Die-casting dies and hot-work dies |
| SUS304 | Austenitic stainless steel | Corrosion-resistant, non-magnetic and not hardenable by quenching | Food and chemical equipment; corrosion-resistant parts |
| SUS303 | Free-machining austenitic stainless steel | Similar to 304, but easier to turn | Automatic-lathe parts and stainless shafts or bolts |
| SUS440C | Martensitic stainless steel | Hardenable, with moderate corrosion resistance | Bearings, knives and parts needing hardness plus corrosion resistance |
| A5052 | Aluminium alloy | Light, easy to weld, corrosion-resistant and not heat-treatable | Sheets, covers and lightweight structures |
| A6061 | Aluminium alloy | Heat-treatable (T6), stronger than A5052 | Load-bearing lightweight structures and machined parts |
| A7075 | Aluminium alloy | Very high strength, close to steel, difficult to weld | Highly loaded parts and tooling |
| FC250 | Grey cast iron | Good vibration damping, easy to cast, brittle | Machine bodies, bases and housings |
| FCD450 | Ductile cast iron | More ductile and stronger than grey cast iron | Load-bearing cast parts |
| C3604 | Free-machining brass | Very easy to machine and electrically conductive | Turned parts, connectors and valves |
