Iron & Metal Alloys

Our Complete range of products are Antimonial Lead Alloy, Lead Alloy, Selenium Lead Alloy and Calcium Lead Alloy.

Antimonial Lead Alloy

Antimonial Lead Alloy that we provide is known for its hardness, tensile strength, high melt fluidity, superior castability and higher stabilization of lead dioxide through ionic migration of SB3+ and SB5+ ion to negative plate. Traditionally, 5- 11% antimony was used by the battery industry. But, the antimony was brought down to 2.5% with addition of selenium as grain refiner to provide enhanced performance. The antimony got further reduced to 1.6% by weight to achieve maintenance-free properties of battery. Our Antimonial Lead Alloy is known for purity and accurate composition. Moreover, clients can obtain bulk quantities of Antimonial Lead Alloy at very reasonable prices from us.
