The most suitable composition of Pd-Ag alloys added In and/or Sn for porcelain fusing was determined by means of the measurement of the mechanical properties (tensile strength, elongation and hardness). The results were summarized as follows: (1) This highest tensile strength was obtained when 5% In and 5% Sn, or 10% Sn were added to the 60 Pd-40 Ag mother alloy, and it was about 52 kgf/mm2 (570 MPa). (2) The effect of the addition of In and Sn to the tensile strength depended on the concentration of Pd and Ag. (3) The elongation increased with increase of the amount of Pd. (4) The Vickers hardness number of the alloys was ranged between 100 and 200. It increased with increase of Ag or Sn content. (5) The most suitable compositions of Pd-Ag alloys for porcelain fusing deduced from the properties such as the bonding strength (in part 1), the thermal expansion coefficient (in part 2) and the mechanical properties (in this paper) were 60 Pd-40 Ag or 64 Pd-36 Ag with addition of 4 Sn-6 In or 8 Sn-2 In. Some characteristic properties of these alloys were as follows; the bonding strength 220 kgf/cm2 (22 MPa), thermal expansion coefficient 14.7 +/- 1x10(-6)/degrees C, thermal expansion hysteresis. 0.00 approximately 0.02%, tensile strength 51 kgf/mm2 (500 MPa), elongation 5% and Vickers hardness number 160 approximately 190.
通过测量力学性能（拉伸强度、伸长率和硬度），确定了添加铟和/或锡的钯银合金用于烤瓷熔附的最合适成分。结果总结如下：(1) 向60Pd-40Ag母合金中添加5%铟和5%锡或10%锡时，可获得最高拉伸强度，约为52 kgf/mm²（570 MPa）。(2) 铟和锡的添加对拉伸强度的影响取决于钯和银的浓度。(3) 伸长率随钯含量的增加而增加。(4) 合金的维氏硬度值在100至200之间，随银或锡含量的增加而增加。(5) 根据结合强度（第一部分）、热膨胀系数（第二部分）和力学性能（本文）等性能推导出的用于烤瓷熔附的钯银合金最合适成分是添加4Sn-6In或8Sn-2In的60Pd-40Ag或64Pd-36Ag。这些合金的一些特性如下：结合强度220 kgf/cm²（22 MPa）、热膨胀系数14.7±1×10⁻⁶/℃、热膨胀滞后0.00至0.02%、拉伸强度51 kgf/mm²（500 MPa）、伸长率5%、维氏硬度值160至190。
