What is T5K10?
Т5К10 is a GOST WC–TiC–Co cutting grade with about 5% TiC in a 10% cobalt binder, the CIS equivalent of YT5 and of C5-class steel-cutting carbide. It is used for roughing and heavy interrupted cuts on steel, where the TiC addition resists crater wear while the high cobalt content keeps the edge from chipping; typical forms are brazed tips, pressed inserts and blanks, with HIP and CVD-coated conditions available. Density is 12.7 g/cm³ and elastic modulus 540 GPa, but thermal conductivity is only 21 W/m·K and service temperature tops out near 800 °C. It is brittle and not fusion weldable; Т15К6 is the finishing-side alternative. T5K10 has a density of 12.7 g/cm³ (0.459 lb/in³), heavier than 83% of ceramic grades. It melts at 1,370°C (2,498 °F). T5K10 has a tensile strength of 900 MPa (131 ksi), stronger than 83% of ceramic grades. The elastic modulus is 540 GPa (78.3 Msi).
What is T5K10 used for?
- Steel roughing turning inserts
- Brazed lathe tools for heavy interrupted cuts

- Heavy — 12.7 g/cm³ (0.459 lb/in³), worse than 83% of ceramic grades
- Needs corrosion protection — 50/100, worse than 83% of ceramic grades

Working with T5K10
Is T5K10 easy to machine?
After sintering it can only be shaped by diamond wheel grinding, EDM or laser cutting; conventional cutting is not possible.
Can T5K10 be welded?
Not fusion weldable; braze to steel shanks with silver-based Ag-Cu-Zn filler (BAg types) at 700–900 °C in vacuum or with a torch, then cool slowly to avoid braze cracking.
Can T5K10 be formed, bent or molded?
Powder-metallurgy pressing or extrusion followed by vacuum or low-pressure sintering at about 1400–1500 °C; sintering shrinkage is roughly 18–20% and no secondary plastic forming is possible.
T5K10 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| TiCtitanium carbide, raises red hardness and crater wear resistance | 4 – 6 | 5 |
| Cocobalt binder phase | 9 – 11 | 10 |
| WCtungsten carbide matrix, grain size about 1.5–3 µm | balance | — |
What surface finishes work on T5K10?
Diamond grinding and lapping reaches Ra 0.05 µm; CVD/PVD coatings (TiN, TiCN, Al₂O₃) raise wear resistance, and electroplating is not suitable.

T5K10 — frequently asked
What is T5K10 used for?
T5K10 is typically used for steel roughing turning inserts, brazed lathe tools for heavy interrupted cuts, planing and shaping tool tips, face milling inserts for forgings, machining of steel castings with scale and boring bar tips for rough passes. In short: tough steel-roughing carbide; interrupted-cut TiC grade; higher cobalt than Т15К6.
What is the tensile strength of T5K10?
T5K10 has a typical tensile strength of 900 MPa (131 ksi) — stronger than 83% of ceramic grades.
