In this study, iron based powder metal (PM) compacts are sintered by two different sintering methods. One of the sintering methods is conventional sintering, 2kW atmosphere controlled oven is used in the sintering application. TM compacts are sintered at 1120°C for 30 minutes.  In the study other used sintering method is induction which is a novel and fast. PM compacts are sintered at a temperature of 1120°C for 1 to 10 minutes using a 900 kHz ultra-high frequency induction system (UHFIS) with a power of 2.8kW. Hardness, density and microstructure images of PM compacts are examined and compared each other. When the obtained results are evaluated, 30 minutes conventional sintered PM compacts test results’ are reached in 5 minutes using by UHFIS. Thus, iron-based PM compacts are sintered in 6 times less dwell time while using the induction system.
