UK Manufactured Lead Ingots — Foundry Stock, Ballast & Casting Feedstock
Heaps, Arnold & Heaps Ltd manufactures lead ingots at our Rotherham facility for foundries, lead alloy producers, casting shops, ballast contractors and industrial users across the UK and internationally. With over 250 years of lead manufacturing experience — established 1770 — we cast ingots in standard 5kg, 10kg, 15kg, 20kg, 25kg and 50kg sizes, in pure refined lead and bespoke tin/lead and antimonial alloy compositions, with full traceability and compliance documentation supplied on request.
Lead ingots are the most fundamental product form in the lead industry: solid cast blocks of refined lead supplied as raw stock for re-melting, alloying, casting, ballast and industrial feedstock applications. The quality, composition consistency and documentation around lead ingots directly affect the downstream products and processes they feed.

Standard Ingot Sizes & Bespoke Weights
Standard Sizes
- 5kg ingot — light handling for small casting shops and laboratory use
- 10kg ingot — common for low-volume foundry feedstock
- 15kg ingot — general-purpose industrial supply weight
- 20kg ingot — standard production-line feedstock
- 25kg ingot — bulk foundry and alloy production
- 50kg ingot — large-scale industrial melt operations
Bespoke Ingot Weights
For specific production-line requirements, melt-pot capacities or handling constraints, we cast ingots to bespoke weights. Common bespoke sizes include 1kg, 2kg and 100kg ingots, plus profiled ingots that match specific customer melt-pot geometries.
Lead Ingot Alloy Compositions
The alloy composition of a lead ingot determines what it can be used for downstream — whether it goes into solder, plating anodes, ballast or specialist alloys. We supply standard compositions from stock and cast bespoke alloys to customer specification.
Pure Refined Lead
Maximum-purity lead, the standard composition for shielding, ballast and most general industrial applications. Suitable for re-melting into cast lead components, radiation shielding and high-density ballast.
Antimonial Lead
Lead with added antimony (typically 1–6%) for increased hardness, structural strength and dimensional stability. Specified for:
- Lead-acid battery grid production
- Hard chrome plating anodes — see our chrome plating anodes
- Structural lead castings requiring mechanical strength
- Cable sheathing for legacy MV/HV cable repair
Tin/Lead Alloys
Lead with added tin in customer-specified ratios. Used for:
Bespoke Alloy Compositions
For specialist applications, we cast ingots to customer alloy specification, including:
- Silver-bearing lead alloys for high-stability electroplating
- Calcium-bearing lead for maintenance-free battery applications
- Multi-element alloys to proprietary downstream process requirements
- Specific antimony, tin or silver percentages to non-standard ratios
Lead Ingot Applications
Foundry Casting Stock
The primary use of lead ingots is as raw stock for re-melting in foundry casting operations. Ingots melt to a known and consistent composition, allowing the foundry to maintain alloy specification across batches without contamination from mixed-source scrap. Supplied to:
- Independent lead and lead alloy foundries
- OEM in-house casting operations
- Small-batch and prototype casting shops
- Specialist alloy production facilities
For smaller melt charges and high-throughput production-line feeding, see our lead pellets — which melt more rapidly but cost more per kilogram.
Specialist Alloy Production
Lead ingots are the base feedstock for the UK’s specialist alloy industries:
- Solder production — both traditional leaded and tin-lead industrial solders
- Pewter manufacturing — traditional tin/lead/antimony pewterware
- Bearing alloys — white metal and babbitt bearing compositions
- Pipe organ pipe metal — lead/tin alloys cast into organ pipes
- Lead-acid battery grids — antimonial and calcium lead alloys
Ballast & Heavy Weighting
Lead ingots are sometimes used directly as ballast without further processing — particularly in marine applications where their compact form and high density make them practical site-fitted ballast units. The 25kg and 50kg ingot sizes are common ballast formats. Supplied to:
- Yacht builders for keel ballast installations
- Marine equipment manufacturers
- Test weight and calibration mass producers
- Industrial counterweight installations
See also our lead ballast for purpose-cast ballast shapes, and our lead products for marine and offshore engineering overview.
Radiation Shielding Stock
For installations producing their own bespoke shielding components in-house, lead ingots provide the raw stock for casting custom shielding. Pure refined lead ingots give the highest shielding density. See our lead shielding bricks and rails for the standard shielding range, and our industry overviews for medical radiation shielding and nuclear applications.
Other Industrial Applications
- Heritage and conservation lead supply for restoration foundries
- Laboratory and research applications
- Specialist industrial process feedstock
- Calibration and reference mass production
REACH, RoHS & Material Compliance
Lead is a regulated substance under EU REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and is listed on the Substances of Very High Concern (SVHC) candidate list. Lead is also restricted in electrical and electronic equipment under RoHS (Restriction of Hazardous Substances), with specific exemptions covering many industrial and specialist applications.
Documentation Supplied with Lead Ingots
- Certificate of analysis — stating alloy composition by element
- Certificate of conformity — confirming source, manufacturer and specification
- REACH declaration — confirming registration status and applicable use
- RoHS statement — addressing applicable exemptions for the customer’s intended use
- Material safety data sheet (MSDS) — handling, storage and disposal information
Documentation is supplied on request and is suitable for inclusion in procurement records, customer audits and regulatory compliance files. Customers in regulated downstream sectors — defence, nuclear, medical, electronics — should confirm specific documentation requirements when placing the order.
See our accreditations and compliance page and download MSDS sheets.
