FAQs about the topic lead-free

Because lead is a toxic metal that can have negative effects on the environment and  human health, the EU RoHS Directive 2011/65/EU restricts its use in electrical and electronic equipment. The use of lead-free materials is intended to reduce the risk of lead being released into the environment. In addition, the use of lead-free materials can improve the recyclability of electronic components and promote the circular economy.

Colloquially, the terms "lead-free" and "RoHS-compliant" are often equated and used synonymously in connection with the material composition. In fact, products are described as "lead-free" if their lead limit value is a maximum of 0.1 % by weight. Exemption 6c in Annex III of the RoHS Directive allows "copper alloys with a lead content of up to 4 % by weight" and are considered "RoHS compliant".

Our lead-free LF Powerelements have a lead content of less than 0.1% and therefore meet the RoHS compliance requirements without the use of temporary exemption 6c.

The Original Powerelements consist mainly of the copper alloy machining brass (CuZn39Pb3). Lead as a minor component of approximately 3% provides good chip breaking and light lubrication. This reduces friction, resulting in less heat generation in the machining process. Without lead, machinability deteriorates, resulting in increased demands on the manufacturing process. We have mastered these requirements with the development of the LF Powerelements.

Exemption 6c in Annex III allows "copper alloys containing up to 4% lead by mass". This exemption actually expired on July 21, 2021. As the responsible EU Commission has not yet announced a decision on a possible extension, the exemption remains valid until further notice.

The RoHS exemption 6c was due to expire on July 21, 2021 for equipment categories 1-7 and 10, and partially for categories 8 and 9, on July 21, 2021. However, a number of applications for an extension of the exemption have been submitted on time and are currently under review to determine the scope for an extension of the exemption. As a result, exemption 6c will continue to apply until the EU Commission has decided on these applications, but this may change at any time following a decision by the EU Commission. To understand how this decision may impact your development and product lifecycle, please read our scenario analysis.
