Dental and orthodontic articles comprising alloys of a material selected from the group consisting of Ti, Zr, Si, Mo, Co, Nb and Be. The alloys may further include at least one secondary alloying element selected from the group consisting of Ta, Cr, Al, V, Pd, Hf and Fe. The alloys preferably comprise a primary constituent in the range of about 30-85% by weight of the alloy, a secondary alloying component in the range of about 0.5-10% by weight, and the alloy has a modulus of elasticity in the range of about 5 million to 15 million psi.
