Ni-Cr and Co-Cr alloy uncontained Be element for using as dental porcelain alloy were analyzed the mechanical properties through bonding strength and fracture test after the bonding with porcelain. The bonding strengths between alloy and ceramic were measured through the shear bond strength test. Consequently, the T-3 group contained Be element that had shear strength of 41.13(${pm}5.11$)MPa was showed the highest shear strength than the other groups. The second highest group was a verabond contained Be element that had shear strength of 40.72(${pm}5.98$)MPa. The results of the other groups according to the shear strength were Wirobond(38.40(${pm}9.66$)MPa) belonged to Co-Cr alloy, and Verabond 2V(32.77(${pm}4.31$)MPa), Bellabond N(28.63(${pm}6.39$)MPa), Bellabond plus(24.97(${pm}6.13$)MPa), Argeloy N.P. Star(22.69(${pm}3.41$)MPa) uncontained Be element, respectively. The morphological aspects of the fracture surface between alloys and ceramic were observed that all groups were caused mixed failure as conformation attached ceramic fragments to metallic surface by fracture process.
