Characteristics:
- Very soft: Without support, it can sag and become distorted
- Dense
- Durable
- Malleable
- Low melting point
- Long life-span (in milder climates, lead roofs have been known to last 200-300 years)
- Generally corrosion-resistant - has little to no reaction with most compounds and solutions.
- Resistant to corrosion by most acids including chromic,sulfuric, sulfurous and phosphoric acids.
- Corrosive to alkalis (such as lime mortar, portland cement and uncured concrete), tannic acid found in wood, and radiation.
- Corrosive to hydrochloric, hydrofluoric, acetic, formic and nitric acids.
etc.
Applications:
- X-ray shielding in the medical and dental field
- Lead shielding for personal protection
- Nuclear shielding in the power generation industry
- Nuclear shielding for research in industry and university
- Radiation shielding for the military
- X-ray shielding to protect workers at security x-ray machines
- Sheet roofing
- Decorative spandrels
- Gutters, leader heads and downspouts
- Cast decorative features and sculpture
- Cupolas, spires and mullions
- Sheathing for cables
- Sheet lead partitions (good for noise reduction)
- Pads for vibrating machinery
- To waterproof ironwork where the iron is fitted into stone.
- Ballast, gaskets, type metal, terneplate and foil
- Building construction materials (such as sheet, pipe, solder, and wool for caulking)
- Materials used in marine power,
- Manufacture of batteries , paint, shells, welding materials, bearing materials, caulking materials,etc.
- Lead-based paint: Red lead is typically used as a corrosion inhibitor for use on iron. White lead is used more frequently in commercial applications. White lead is not intended for use on iron
- its use will increase corrosion, especially on wrought iron.
