Lead
High density lead also gives resistance to rays. Therefore, it is used as a protection screen in nuclear reactors, X-ray generators and gamma-ray sources.
Lead is very resistant to abrasion. This makes it very useful in water pipes, roofing and cable protection. However, in these applications, plastics, which both have the properties of lead and are lighter and more resistant to creep (slow deformation), are gradually replacing lead. However, lead is still widely used in the chemical industry due to its resistance to sulfuric acid.
