| Code | Name | Characteristics | G(kgf/mm2) | Specific gravity (g/cm3) | Feature Description |
| SWRM | Low carbon steel wire SAE1008 | Widely used | 8000 | 7.85 | The strength is low, but the toughness is good, the weldability is good, and the cold stamping property is excellent. It is often used to manufacture products such as chains, rivets, bolts, and shafts. |
| SW-A | SWC | Widely used | 8000 | 7.85 | Hard steel wires are classified and named according to their carbon content, diameter, mechanical properties and use. JIS G 3521 divided into three types: SW-A, SW-B and SW-C. According to the carbon content of the wire, the hardness is determined. The minimum carbon content is 40C and the maximum is 80C. |
| SW-B | Hard steel wire Type B | Widely used | 8000 | 7.85 |
| SW-C | Hard steel wire Type C | Widely used | 8000 | 7.85 |
| SWPA | Piano wire Type A | Widely used, Corrosion resistant | 8000 | 7.85 | General use, high durability, piano steel wire can be used for engine valve springs, mechanical springs and musical instruments. |
| SWOA | Oil tempering line Type A | Widely used | 8000 | 7.85 | Oil tempered carbon steel wire for spring SWO (JIS G 3560), Oil tempered carbon steel wire for general valve SWO-V (JIS G 3561), Oil tempered chrome vanadium steel wire for fatigue resistance valve SWOCV-V (JIS G 3565 ) Heat and fatigue resistance 41-55 Spring material that is more durable than piano steel wire. Commonly used in car shock absorbers, engine valve springs. |
| SUSWPA | Stainless steel wire No.1 | Widely used, Heat resistant, Corrosion resistant | 7000 | 8.02 | 304 is a general-purpose stainless steel that is widely used to make equipment and parts that require good overall properties (corrosion resistance and formability).
301 stainless steel exhibits obvious work hardening phenomenon during deformation, and is used in various occasions requiring higher strength.
302 stainless steel is essentially a variant of 304 stainless steel with higher carbon content, which can obtain higher strength by cold rolling.
316 stainless steel contains aluminum, so its resistance to pitting corrosion in marine and chemical industry environments is much better than 304 stainless steel. |
| BeCuW | Beryllium copper wire | Conductive, Non-magnetic, Corrosion resistant | 4500 | 8.6 | Also known as copper beryllium, beryllium bronze or spring copper, it refers to a copper alloy with a beryllium content of 0.5 to 3%, sometimes adding other alloying elements. Beryllium copper is a non-magnetic, non-sparking high-strength material with excellent metal processing. It has many applications in harmful environments, musical instruments, precision measuring devices, ammunition and aerospace. |
| PBW | Phosphor‑bronze wire | Conductive, Non-magnetic, Corrosion resistant | 4300 | 8.8 | Phosphor bronze wire is a high strength copper alloy with excellent corrosion resistance, fatigue strength, mechanical properties and electrical conductivity. Uses Springs, guitar strings, high-performance electrical terminals, electronic latches, electroplating hooks, mechanical and hardware parts. |
| BsW | Brass wire | Conductive, Non-magnetic, Corrosion resistant | 4000 | 8.5 | |
