Product Overview
What is Lead Alloys?
Lead is a soft, dense metal that is typically alloyed with elements such as antimony, tin, and calcium to improve its mechanical properties like strength and hardness. These alloys are widely used in a variety of industrial applications, especially in the production of lead-acid batteries, radiation shielding, and solders.
Properties of Lead Alloys
Pure lead is a soft metal with low tensile strength and a low melting point of 327.5 °C (621.5 °F). Alloying with other metals enhances specific properties:
- Increased Strength and Hardness: Antimony is the most common alloying element used to significantly increase the strength and hardness of lead.
- Corrosion Resistance and Ductility: Lead alloys generally maintain lead's inherent excellent corrosion resistance and ductility..
- Improved Casting and Flow: Additions like tin can improve fluidity and casting performance for specific applications such as intricate molds or long-spined battery grids.
- Radiation Shielding: Due to lead's high density, its alloys are widely used for attenuating radiation, especially X-rays, in nuclear medicine and radiotherapy.
