Product Description

<<Polycrystalline Cubic Boron Nitride>>

Polycrystalline Cubic Boron Nitride consists of CBN grain and specific ratio of adhesive. PCBN is sintered in high temperatures and high pressure.

The specialties of Polycrystalline Cubic Boron Nitride:

1. High hardness (inferior to diamond), abrasion resistance, crash resistance.

The micro-hardness of CBN grains is HV8, 000~HV9, 000; the hardness of PCBN is HV3, 000~HV5, 000.

2. High heat stability.

Polycrystalline Cubic Boron Nitride still shows the good heat stability in 1, 200°C~1, 500°C.

3. Good chemical stability (better than diamond)

Polycrystalline Cubic Boron Nitride will not have chemical reaction with Fe, Ni, and Co at 1, 200°C~1, 300°C, it is not eroded in acid solution and would be eroded in alkali solution at about 300℃.

4. Good heat conduction

The heat conduction of Polycrystalline Cubic Boron Nitride is lower than that of diamond. Its heat conduction is 20 times as hard alloy. In addition, the heat conduction of Polycrystalline Cubic Boron Nitride becomes higher with the increase of temperature.

Polycrystalline Cubic Boron Nitride does not react chemically with iron in ferrous material work pieces. The applications of Polycrystalline Cubic Boron Nitride are Ferrous Materials, Metal Alloys, Hardened steels (HRc 59~HRc62), Hard facing alloys (>HRc 35), Grey Cast Irons (200~280 HBN), Hot/cold worked tool steels (45 - 65 HRc), High speed steel (45 - 65 HRc), Alloyed steels, Titanium alloys, and etc. but not suitable for processing soft ferrous metal.
