The porous sintered bronze alloy has widespread applications in various engineering fields such as filtration systems, self-lubricating bearings, fluid flow control, heat exchanger ..etc. In this paper, a powder metallurgy technique using NaCl particles high purity (99.5%) as a space holder (pore-forming agent) was employed to produce a rigid porous structure. The paper aimed at studying and identifying the effect of manufacturing parameters (NaCl wt. %, compacting pressure, sintering temperature, and sintering duration) on the characteristics of porous tin-bronze alloy. According to Response Surface Methodology analysis, a multi-optimization method based on desirability function is used to obtain the optimum process conditions that can be used in the manufacturing of porous sintered tin-bronze structure. These optimum conditions were: (35.36 wt.%NaCl), (40 MPa) compacting pressure, the sintering temperature of (193.5 oC) and sintering time of (180 min) to get maximum porosity of (66.32 %), permeability coefficient of (2.96*10-3 cm/min.) and micro-hardness of (57.12 Hv).
