The present invention provides metal alloys that comprise at least copper, zinc and aluminium and, in addition, include manganese and iron, for the production of horseshoes that have bactericidal and fungicidal properties, impeding the proliferation of bacteria and fungi specific to equines and mitigating the effects of vibration on equine joints, absorbing impacts known as "absolute shock".metal alloys composed principally of copper and horseshoes made with said alloys.
