While lead is not used as much as it has been in the past, it is still an essential material in many types of applications. For most people, lead is associated with radiation protection, and it is still one of the most effective options for high and low levels of radiation protection.
Uses of Lead Today
In other industries, lead is used for a variety of other applications. Lead is commonly used as flashings on roofing vents, around chimneys as well as other types of structural components on the roof. Its durability combined with the malleability of the material makes it a natural option.
Lead is also used in plumbing, although no longer as pipe for potable water. Lead can be used as a material to join pipes, and it can be used in both soldering as well as the flux and is typically purchased in the form of casting lead ingots for small volume applications. This makes handling, storage and use on the job much easier and more convenient.
In addition to some limited plumbing applications for non-potable water as well as in roofing applications, lead can also be used for soundproofing material. It is also used in marine types of construction and in various type of production and manufacturing industries.
The Choice of Ingots
Ideally, choose casting lead ingots that are of a convenient size. The most practical consideration for most applications are those in 5-pound ingots on strings of 5, for a total weight of 25 pounds.
Check the purity of the casting lead ingots. For most applications, a 99.7% pure lead is all that is required. However, there are a small number of manufacturers producing a 99.9% lead option, which is often required in specialized types of applications.
