N-650 Zirconia engineering ceramics

Zirconia(ZrO2)

Zirconia has excellent hardness and toughness, wear resistance, and it has good electric insulation and chemical resistance too.

As I introduce this is a strong, durable, sturdy material, the material is used for the wear resistant component and machine parts.

A thermal conductivity of the zirconia material is very low (3w/m・K), so It is used for a heat insulator as well.

N-650B Black Zirconia engineering ceramics

N-650B ジルコニア黒色 Nishimura advanced ceramics provide a color zirconia ceramics, and this is a black version.

Machine parts, Optical parts, Spindles and looms parts, and measuring equipment.

It is also used for ornaments.

N-660B Blue Zirconia engineering ceramics

青ジルコニア

Nishimura advanced ceramics provide a color zirconia ceramics, and this is a blue version.

Machine parts, Optical parts, Spindles and looms parts, and measuring equipment.

It is also used for ornaments.

N-650H Hipped Zirconia engineering ceramics

ジルコニアN-650H(HIP) Nishimura advanced ceramics take the HIP processing for producing the hipped zirconia material.

HIP is the name of the processing. Nishimura advanced ceramics take this process with burnt zirconia ceramics. The HIP process gives heat and pressure.

HIP zirconia has better strength than a zirconia material.

The material is suited for wear resistant/antifriction component like a cutter or punching tool. It has high wear proof performance.

Highest Fracture toughness Zirconia N-631

n631bkmr This is a Zirconia which has fracture toughness 9.2MPa・m1/2 Zirconia(Approx.1.5~2 times higher fracture toughness than usual Zirconia)
It can be used as a smart phone parts, cutter, case, cutting tool, positioning pin, measuring probe, and more.
