An elastomeric material for articles such as dynamic seals (20) and the like is rendered detectable by conventional metal detectors (18) through the incorporation of particles of a metallic alloy (22). Preferably, the resulting impregnated material contains at least 0.25 % and no more than 50 % by volume of the alloy, with 2 % by volume being the most favored. In one embodiment, the alloy contains 11.0 % to 22.0 % by weight of Iron, 70.0 % to 90.0 % by weight of Nickel, and 0.0 % to 7.0 % by weight of Molybdenum. In another embodiment, the alloy contains 14.0 % to 19.0 % by weight of Iron, 80.0 % to 83.0 % by weight of Nickel, and 1.0 % to 3.0 % by weight of Molybdenum, and in the most preferred embodiment, the alloy contains about 15.43 % by weight of Iron, about 82.39 % by weight of Nickel, and about 2.17 % by weight of Molybdenum.
