Element 82

Two elements. A whole industry.

From lead, and from zinc, we make the oxides, alloys and stabilizers other industries are built on. And where lead does not belong, we make the lead-free alternative.

  • PbO · litharge
  • Pb · pure lead
  • Pb–Sb · alloys
  • ZnO · zinc oxide
  • Ca/Zn · lead-free stabilizers

A day with Waldies

All day, without a second thought.

  1. Water from the tap

    It reaches you through lead-free PVC pipes, made with Virichem® calcium-zinc stabilizers.

  3. A power cut. The inverter takes over

    Tubular inverter batteries depend on high-purity red lead.

    Battery metals →
  4. Lights, fans and machines run

    Through wires and cables insulated with compounds we stabilize.
