Lead Calcium Alloys (Pb-Ca-Sn-Al)
Veer Alloys produces specialized Lead Calcium Alloys (Pb-Ca-Sn-Al) with tightly controlled Calcium (0.06% - 0.11%) and Tin (0.3% - 1.2%) percentages. Calcium replaces antimony to virtually eliminate water consumption and self-discharge in modern automotive batteries. Trace Aluminum prevents Calcium oxidation in foundry kettles, ensuring maximum alloy utilization.
