Abstract
Un objet solide présentant une frangibilité maîtrisée, telle qu'une balle ou une enveloppe pour explosifs, est constitué par combinaison de deux métaux différents dans des proportions calculées pour obtenir une densité voulue, sans utilisation de plomb. Une matière humidifiante est déposée sur le constituant de base, lequel est constitué d'une matière dure relativement dense. La matière humidifiante améliore l'aptitude à l'humidification du constituant de base avec le constituant liant, lequel est plus léger et plus tendre que ledit constituant de base.
