Overview of Lead Stock Options

Lead stock from Nuclead is available in a variety of standard and custom forms to suit different industrial requirements. Each stock format is manufactured to tight tolerances, with options available in pure or alloyed lead.

Lead Rounds

Lead rounds are cylindrical rods cast or machined to consistent diameters and lengths. These are commonly used for ballast, casting, radiation shielding, and vibration damping.

• Available in diameters from under 1″ to over 10″

• Cut to specified lengths or supplied in full bars

• Can be drilled, tapped, or shaped for custom integration

• Ideal for applications needing compact mass

Lead Bars

Lead bars provide a rectangular cross-section with flat surfaces, suitable for stacking, mounting, or cutting into parts. They are commonly used in construction, shipbuilding, and as counterweights.

• Supplied in standard sizes or cut to customer specifications

• Great for building lead assemblies, lining, and stabilizers

• Easy to handle and install in various mechanical settings

Lead Blocks

Solid lead blocks are used when large volumes of weight or radiation protection are needed in a compact space. They can be molded, stacked, or machined as needed.

• Extremely dense for maximum performance in limited space

• Used in elevator counterweights, medical shielding, and industrial balancing

• Available with encapsulated coatings upon request

Custom Lead Stock

Nuclead provides custom lead stock machined or molded to fit project-specific dimensions, weights, and tolerances. Whether for OEM components or prototype development, custom lead stock can reduce machining time and material waste.

• CNC-machined or cast to exact specifications

• Available with holes, inserts, angles, or fittings

• Packaged and labeled for easy assembly

Industrial Uses of Lead Stock

Nuclead’s lead stock serves a wide variety of industrial functions, offering unmatched density, corrosion resistance, and malleability. These properties make lead an essential material in sectors that require stability, shielding, and vibration absorption.

Radiation Shielding

Lead stock is a cornerstone material for radiation shielding in hospitals, laboratories, and nuclear facilities.

• Lead rounds and bars used to build walls, doors, and panels

• Blocks and pucks form barriers for radioactive sources

• Lead-lined cabinetry and enclosures for x-ray rooms and isotope storage

Ammunition and Ballistics

Lead remains a preferred material in ammunition production due to its density and casting properties.

• Used in bullet cores, shot pellets, and explosive molds

• Custom lead bars melted down for reloading or casting

• Military and commercial ammunition manufacturers depend on consistent lead stock

Marine and Subsea Applications

Lead stock is widely used in marine environments as ballast and weight systems, due to its non-corrosive performance under water.

• Lead blocks used in submarines, offshore rigs, and underwater drones

• Bars and rods molded into keel ballast for ships

• Helps maintain vessel balance and reduce rolling

Mechanical Balancing and Vibration Damping

In heavy machinery and rotating equipment, lead stock offers excellent stability and noise control.

• Lead rounds inserted into housings for precise mass balancing

• Bars used to reduce vibration in pumps, motors, and HVAC systems

• Embedded blocks stabilize cranes, elevators, and robotics

Construction and Roofing

Lead stock is used for traditional flashing, counterweights, and sealing joints in buildings.

• Bars and blocks used in historical restoration

• Round stock trimmed and installed for waterproofing and expansion joints

• Excellent for lead-lined walls, partitions, and dampening systems

Research and Experimental Applications

Laboratories and research institutions use precision lead stock in shielding, calibration, and structural experiments.

• Custom discs and rods integrated into test rigs

• Lead stock cut into sample masses for scientific modeling

• Shielding for particle physics and neutron research environments

Lead Material Grades and Options

Nuclead offers lead stock in various material grades based on the intended use. All materials are quality-tested for purity, density, and machinability.

Pure Lead Stock (99.9%+)

• Soft and highly formable

• Best for shielding, molding, and malleable applications

• Low impurity content suitable for radiation and medical use

Lead-Antimony Alloys

• Hardened material with increased strength

• Commonly used in ammunition and structural counterweights

• Maintains dimensional stability over time

Lead-Tin Blends

• Designed for improved flow in casting

• Used in specialized manufacturing, soldering, or coating

• Available by request for technical applications

Coated or Encapsulated Lead Stock

For environments where lead exposure is a concern, stock can be encased in vinyl, epoxy, or metal sheathing.

• Improves safety and hygiene in sensitive applications

• Reduces risk of surface contamination or handling hazards

• Used in hospitals, cleanrooms, and public-access installations
