Additional information on a voluntary Basis:
Solid lead metal, e.g. as a component of a metallic alloy, is considered toxic for reproduction if the concentration limit of 0.3% by weight is exceeded.
We would like to inform you that the use of lead in metallic semi-finished products has been regulated for many years. The information obligation under REACH is not based on new scientific knowledge about the metal. It is based solely on the fact that lead has been added to the REACH candidate list by the European Chemicals Agency. The aim of the inclusion is, among other things, to obtain information on the quantities of these substances used within the EU.
Lead acts as a chip breaker and lubricant in aluminium and copper alloys, improves the machinability of copper alloys and also gives the finished component other properties such as corrosion resistance or better sliding and emergency running properties. The alternatives to the use of copper alloys with a mass content of up to 4% lead cannot currently be considered scientifically or technically practicable. It is also technically impossible to remove the lead unintentionally introduced into the recycling stream.
