Abstract: A silver-based alloy incorporating palladium, magnesium and aluminium in the following proportions of the components, percent by weight:______________________________________ palladium 5 to 30 magnesium 0.1 to 0.5 aluminium 0.01 to 0.5 silver the balance. ______________________________________The alloy of the above-specified composition, in contrast to the known silver-based alloys, possesses a sufficiently high plasticity (relative elongation of the alloy after the internal oxidation thereof is as high as 25%), while retaining a high level of mechanical strength, elasticity, electro-contact and corrosion-resistance properties.
