CTG‑1001‑K23 is a sintered iron‑graphite alloy engineered for applications requiring a balance of structural strength, wear resistance, and embedded solid lubrication. The graphite phase provides inherent lubricity, making this material suitable for dry or boundary‑lubricated service conditions.
| Element | Typical range (wt%) |
|---|---|
| Iron (Fe) | Balance |
| Carbon (C) | 0.5 – 1.0 |
| Graphite | 1.0 – 3.0 |
| Copper (Cu) | 0.5 – 2.0 |
| Manganese (Mn) | ≤ 1.0 |
Graphite content is the defining feature of CTG‑series materials, providing solid lubrication.
| Property | Typical value | Unit |
|---|---|---|
| Density | 6.6 – 7.1 | g/cm³ |
| Ultimate tensile strength | ≈ 40,000 – 55,000 | psi |
| Yield strength | ≈ 30,000 – 45,000 | psi |
| Hardness | ≈ 60 – 85 | HRB |
| Elongation | ≈ 1 – 2 | % |
| Wear behavior | Enhanced by graphite | — |
Mechanical properties depend on density, sintering temperature, and graphite distribution.
| Standard | Designation |
|---|---|
| MPIF | CTG‑1001 |
| ISO | Comparable iron‑graphite grades |
| Forms | Bushings, bearings, structural components |
Equivalency depends on graphite content and density class.
