mLego aims to support its customers in the switch to lead-free alloys by providing efficient technical solutions and by developing new products to better meet their expectations.
Therefore, mLego produces a dedicated range of brass with lead content less than 0.1% including High Tensile Brass.
Lead content less than 0,1% is in accordance with Europe ELV (End of life Vehicles) and RoHS (Restriction of Hazardous Substances) directives and their potential future evolution.
mLego is also an active member of several working groups focused on the lead-free brass topic in collaboration with the French CETIM and the Pole Mont Blanc Industries
mLego Lead-Free Brass alloys do not contain any of the below components:
- Chromium VI
