　■ Sintered properties of JIP pure iron powder

（1）	“JIP” iron powders exhibit excellent reactivity with a variety of alloying elements, making it possible to produce high-strength sintered products.
（2）	As“JIP” iron powders are manufactured under the strict quality control system, they show extremely low variation in sintered product properties such as dimensional change.
（3）	As for dimensional change during sintering, reduced iron powders tend to shrink more comparing with atomized iron powder. This is one of the great features of “JIP” reduced iron powder.

Composition	：	Fe–1.5% Cu–0.5% Gr+1.0% ZnSt
Sintering temperature and time	：	1130°C × 20min.
Sintering atmosphere	：	Endothermic gas, D.P. 0°C
