ABSTRACT

Antimony plays a crucial role in lead-based alloys, primarily enhancing their mechanical properties and resistance to corrosion. It is commonly used as a hardening agent in lead alloys, improving their durability and performance in various industrial applications. However, the use of antimony has become increasingly problematic due to its limited availability and the challenges associated with its procurement. This article addresses the need to replace antimony with alternative alloying elements, exploring potential substitutes that can provide similar or enhanced properties. The paper investigates various alloying elements, such as tin, copper, and others, evaluating their effectiveness in replacing antimony in lead-based alloys. It also examines the impact of these substitutions on the physical, mechanical, and chemical properties of the alloys. The aim is to offer a comprehensive understanding of how these alternative elements can optimize the performance of lead alloys, ensuring sustainability and reliability in their applications.
