High-Purity 99.994% Lead Ingot

These are refined lead ingots cast to a standard 25 kg block measuring 645 x 128 x 90 mm, at a minimum purity of 99.994%. The grade is a refined-metal designation: the ingot has been through smelting and refining rather than recovered as secondary scrap, so the analysis is controlled rather than merely observed.

Lead is bought for two properties above all: density and corrosion resistance. Density is what makes it work as radiation shielding, where stopping power scales with mass per unit area. Corrosion resistance is what makes it survive decades in a battery or a chemical plant. Both depend on purity — impurity elements such as bismuth and antimony raise hardness and change the electrochemical behaviour of the alloy, which is why battery manufacturers specify a floor on the lead content rather than accepting whatever the lot happens to be.

Refined lead ingots are consumed in:

• Lead-acid battery grids, plates and terminals
• Radiation shielding for medical and nuclear applications
• Lead alloys, including solders and bearing metals
• Cable sheathing and corrosion protection
• Ballast weight and vibration damping

For battery work, tell us whether the ingot is being cast into grids or into oxide, because the two processes tolerate different bismuth and antimony levels. For shielding, give the attenuation requirement and the thickness you intend to cast — density is the input to that calculation, and the purity figure confirms the density is what you expect.

Also state whether you need the ingot in full block form or cut, and the tonnage and destination port. Lead is a controlled material in many jurisdictions, so mention any documentation your market requires at enquiry stage rather than after the container is sealed.

Ingots are stacked and strapped in bundles for container loading, or supplied loose if your works prefers to handle them individually. Because lead is dense, the packing form has a larger effect on loaded weight here than it does for lighter metals, so it is settled with the quotation rather than assumed.

Every lot ships with a certificate of analysis stating the full chemical composition, produced under an ISO 9001:2015 quality management system. That is more than the headline purity figure: it is the residual elements that decide whether two lots at the same stated purity behave the same way in your process.

You can nominate an independent inspection agency — SGS and BV are the two we handle most often — for pre-shipment sampling, weight verification and container sealing. The report is issued to you rather than to us, and you are equally welcome to send your own representative.

Standard export documentation covers the commercial invoice, packing list, certificate of origin and bill of lading, alongside the chemical composition report. If your market requires an additional declaration, tell us at quotation stage rather than after the container is sealed. See the terms of service for how inspection and claims are handled.
