Copper and Bismuth Are What Kill Your Grids. We Take Them Out.
Trace copper and bismuth are what turn into grid corrosion, short cycle life and warranty claims eighteen months later. Two-stage de-coppering and Harris refining take both to ppm, and every batch is assayed before it ships.
The problem we solve.
You do not see inconsistent purity when the container arrives. You see it as grid corrosion, then capacity loss, then warranty claims a year later.
Grid Corrosion
Trace copper and bismuth accelerate grid degradation, reducing battery cycle life.
Inconsistent Oxide
Variable purity means variable oxide quality, leading to inconsistent paste formulations.
Failed Batteries
Impurities that pass incoming QC still show up in field failures and warranty claims months later.
Supplier Switching Costs
Every time you change suppliers, you re-qualify the material, adjust your process, and absorb downtime.
What we do differently.
Independent batches
Every production run is smelted, refined, and tested as a discrete batch. No blending across heats.
Full elemental COA
Every shipment includes a Certificate of Analysis covering Pb, Cu, Bi, Ag, Sb, Sn, As, Fe, Zn, and more.
Custom alloys
Need Pb-Sb, Pb-Ca, or Pb-Sn? Send us your target composition. Production in 2-3 weeks.
Applications we serve.
SLI Batteries
Automotive starting, lighting, and ignition batteries. Our 99.98% pure lead ingots meet the purity requirements for high-performance grid casting and oxide production.
Traction Batteries
Forklift, golf cart, and industrial vehicle batteries requiring deep-cycle durability and consistent plate quality.
Standby & UPS
Uninterruptible power supply and telecom standby batteries where grid corrosion resistance is critical for long float life.
Industrial Batteries
Stationary power, renewable energy storage, and large-format industrial applications demanding reliable, traceable lead supply.
Lead Oxide
High-purity lead for oxide production, where even trace impurities affect paste rheology and battery formation efficiency.
