Lead is a soft, dense metal that is ideal for processing using waterjet cutting. Waterjet cutting is a cold-working process in which a high-pressure jet of water is used to cut materials. One of the main advantages of this method is that it does not generate heat, which preserves the structural integrity of the cut area. 

This prevents the material from melting, deforming or other heat effects such as laser cutting or plasma cutting when cutting lead. This is particularly important with lead, as it is susceptible to deformation due to heat. In addition, waterjet cutting enables precise, smooth cuts and is able to cut complex shapes from lead with high accuracy.
