Lead Bricks

For use in Nuclear and Medical Radiation Shielding, along with counterbalance weights and balast
Alchemy’s standard brick products are available in Flat, Tongue and Groove, or V-Type Interlocking
Also available in custom shapes and sizes for your niche application.

The interlocking type provides better elimination of radiation leakage and creates sturdier walls with less chance of toppling. Interlocking types make it easier to erect, modify and relocate walls and cells of any size.

We always build your custom walls on our premises to ensure proper fit on your site, all holes or notches that you require are pre-made for your assembly.

Please specify whether you want Pure Lead or Hi-Hard Bricks.

Containers & Boxes

Whatever the application, from cabinets to boxes & barrels, we can custom build any kind of container you require for your nuclear applications.

Sheet Lead

What We Can Do:

  • 1/64 ” to 1″ Thick (See chart below)
  • Standard roll = 4′ x 10′ and 3′ x 18′
  • Standard roll for 1/64″ = 3′ x 12′
  • Any sizes of cut pieces available

The Benefits:

  • Manufactured from refined pure leads and a variety of special alloys upon request. Conforms to ASTM B-29, B-749 and Federal QQ-L-201F, QQ-L-171E.
  • Many applications including; nuclear shielding, tank linings, roof flashing, sound-proofing, vibration absorbers, waterproofing and x-ray shielding.
  • Yes, we can sell you sheet lead by the roll, but we can also take your specs and fabricate that sheet lead to conform to your specs.
