Purpose: This study was to observe surface property and bonding strength according to composition of Ni-Cr alloy for porcelain fused to metal crown. The two kinds of Ni-Cr alloy with different composition ratio of parent metal were observed general properties and chemical properties of each alloy surface and measured the shear bonding strength between ceramic and each alloys. The aim of study was to suggest the material for design of parent metal’s composition ratio to development of alloy for porcelain fused to metal crown. Methods: The two kinds of alloy as test specimen was Ni(71wt.%)-Cr(12wt.%) and Ni(63wt.%)-Cr(23wt.%) alloy. The oxide on surface was observed by SEM and EDX. And the shear test was performed by MTS. Results: The surface property and oxide characteristic analysis of oxide layer, weight percentage of Element O within Ni71Cr12 alloy measured 12.74wt.%, but Ni63Cr23 alloy was measured 15.91wt.%. And the maximum shear bonding strength was measured 106.14 between Ni71Cr12 alloy and vintage halo (VV group). Conclusion: The surface property and oxide characteristic of Ni71Cr12 alloy was similar to Ni63Cr23 alloy. And VV group has the strongest shear bonding strength.
