No, because Bio Shield disposers are constructed from stainless steel (grinding components) and thermoplastic materials (grinding chamber). With the exception of the Economy unit, all models are covered by a lifetime corrosion warranty. The grinding components on the Economy model have the capacity to corrode eventually; this does not impede the operation of the unit.
