The case is of brass; the bullet is of jacketed hard lead alloy.

For more than 300 years the matrices or molds into which hot lead alloy was poured to produce type were made by metal punches.

They said that 30 million people might drink water from wells equipped with submersible pumps made of lead alloys.

Normal pipes are made by first casting the desired lead alloy onto a long flat surface.

Heat treating can increase the hardness of commonly used lead alloys.

The matrices would be lined up and hot lead alloy forced to fill the matrices, creating the line of type.

He knew that no wave this could detect would pass through lead or a lead alloy.

Depending on requirements, bullet cores are manufactured using one of four different lead alloys:

The projectile was a wasp waisted hourglass shape made of a hard lead alloy.
