Abstract

"BALA DE METAL FRIáVEL, BALA DE METAL FRIáVEL ISENTA DE CHUMBO, RESPECTIVO MéTODO DE FABRICO E CARTUCHO ISENTO DE CHUMBO". Uma bala de metal friável (10), método de fabrico e munição feita a partir do mesmo. A bala de metal friável (10) é formada de uma mistura de partículas de metal e material de formação de ligante metal ou metaloide que é compactado no formato pretendido, aquecido a uma temperatura acima da necessária para formar pelo menos um composto intermetálico, mas, abaixo da temperatura de aglutinação das particulas de metal por sinterização e abaixo da temperatura de formação de quantidades substanciais de uma liga dúctil do metal das partículas e o material de formação do ligante de metal ou metaloide e, depois, arrefecido. Essas balas (10) têm resistência suficiente para manter a sua integridade durante o disparo, mas, desintegrar-se em pó no impacto e podem ser formuladas para serem isentas de chumbo.
