Usable Low-Lead Copper/Brass/Bronze after the deadline of RoHS Lead Exemptions(2021.07.21) 2021-03-12

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).

The RoHs Category Lead Exemptions Deadlines:

July 21,2021              

All categories except for Category 8 in-vitro diagnostic medical devices, Category 9 industrial monitoring & control instruments, Category 11 products
July 21, 2023 Category 8 in-vitro diagnostic medical devices (IVDs)
July 21, 2024: Category 9 industrial monitoring & control instruments; Category 11 products

 

 

 

 

 

 

 

Materials might be affected in our product after deadline (July 21,2021)

  Application Category

6a-1 Lead up to 0.35% by weight in alloyed steel (for machining) and up to 0.2% lead by weight in batch hot-dip galvanized steel Categories 1-7 and 10
6b Lead up to 0.4% lead by weight in aluminium alloys Categories 8, 9 (except for in-vitro diagnostic medical devices and industrial monitoring & control instruments)
6b-I Lead up to 0.4% lead by weight in recycled scrap aluminium alloys Categories 1-7 and 10
6c Lead up to 0.4% lead by weight in copper alloys Categories 1-7 and 10
    Categories 8, 9 (except for in-vitro diagnostic medical devices and industrial monitoring & control instruments)

To meet the new Rohs Lead specification, Kosmos can produce copper parts with following material: C6801、C6802、C6803、C6804, which lead up to 1000ppm lead by weight in copper alloys.

Copper/Brass we can proivde after the deadline (2021.07.21)

Materil No. Cu Bi SN Al Pb Zn Fe Cd Cr Hg Se+Sb+ Te+Al
C6801 57.0~64.0 0.5~4.0 0.2~2.5 <0.1 <0.01 Rem. <0.5 <0.001 <0.001 <0.001  
C6802 57.0~64.0 0.5~4.0 0.2~2.5 <0.1 <0.1 Rem. <0.7 <0.001 <0.001 <0.001  
C6803 57.0~64.0 0.5~4.0 0.2~2.5 <0.1 <0.01 Rem. <0.5 <0.001 <0.001 <0.001 0.02~0.6
C6804 57.0~64.0 0.5~4.0 0.2~2.5 <0.1 <0.1 Rem. <0.7 <0.001 <0.001 <0.001 0.02~0.6

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.
