01  /  Process
Spec to certified alloy

You send the spec, we match it.

Send your target composition and our metallurgists confirm feasibility within 48 hours, then produce and certify against it.

Step01

You send your spec

Share your target alloy composition, element percentages, tolerances, and application requirements. Email, phone, or through our quote form.

Step02

We confirm feasibility

Our metallurgists review your specification and confirm whether we can produce it, with any adjustments noted, within 48 hours.

Step03

We produce and certify

Once confirmed, we produce your alloy, assay each batch against your target spec, and issue a Certificate of Analysis showing target vs. actual composition.

Pb-Sb · Pb-Ca · Pb-Sn

Three alloy families, tuned to your grade.

From flooded grids to maintenance-free VRLA, the base is 99.98% lead and the additions are set to your specification.

System 01 · Pb-Sb

Lead-Antimony

Antimony content from 1% to 11%. The workhorse alloy system for flooded lead-acid batteries. Antimony improves casting fluidity and mechanical strength of battery grids, making it the standard choice for deep-cycle and industrial battery applications.

Flooded battery grids, terminalsPrimary applications
Improved castability, mechanical strength, corrosion resistanceKey properties
System 02 · Pb-Ca

Lead-Calcium

Calcium content from 0.03% to 0.12%. The alloy of choice for VRLA (valve-regulated) and maintenance-free batteries. Calcium reduces gassing, self-discharge, and water loss compared to antimony-based alloys.

VRLA batteries, maintenance-free SLIPrimary applications
Low gassing, reduced self-discharge, lower water lossKey properties
System 03 · Pb-Sn

Lead-Tin

Tin additions improve casting fluidity and enhance corrosion resistance of the positive grid. Often combined with calcium in ternary Pb-Ca-Sn systems for optimized VRLA performance.
