A low melting point Ni-Cr alloy is fusible easily with a low-calorie heat source commonly and easily available. The alloy comprises, Ni, Cr, Cu, Mn and Al as the principal components thereof and an appropriate deoxidizer. There is further added at least one alloy element selected from the group consisting of Ga, Nb and Zr or other alloy elements if circumstances permit. The low melting point of the alloy disclosed herein simplifies casting facilities, makes plaster molds usable and facilitates the removal of products after casting.
