Usable Low-Lead Copper/Brass/Bronze after the deadline of RoHS Lead Exemptions(2021.07.21) 2021-03-12
.jpg)
Seven exemption groups have been approved for the use of lead in certain applications under EU RoHS Annex III for a few more years. In the past, Copper alloys products lead up to 0.4% by weight. But after the exemption deadline July 21 2021, Lead (Pb) tolerance will decrease from 0.4% (40,000ppm) to 0.01% (1000ppm).

But considering the higher price of these Low-Lead Copper, we rather recommand to replace the material from copper to stainless steel. The price of Stainless steel can meet the new Rohs Lead specification, and cheaper sometimes.
