The Sunyaev-Zel'dovich Effect (SZE) has been observed toward six massive galaxy clusters, at redshifts 0.091 <= z <= 0.322 in the 86-102 GHz band with the Y. T. Lee Array for Microwave Background Anisotropy (AMiBA). We modify an iterative method, based on the isothermal {beta} models, to derive the electron temperature T_e_, total mass M_t_, gas mass M_g_, and integrated Compton Y within r_2500_, from the AMiBA SZE data. Non-isothermal universal temperature profile (UTP) {beta} models are also considered in this paper. These results are in good agreement with those deduced from other observations. We also investigate the embedded scaling relations, due to the assumptions that have been made in the method we adopted, between these purely SZE-deduced T_e_, M_t_, M_g_, and Y. Our results suggest that cluster properties may be measurable with SZE observations alone. However, the assumptions built into the pure-SZE method bias the results of scaling relation estimations and need further study. Key words: cosmic background radiation, cosmology: observations, galaxies: clusters: general
