CUPAL RoHS / REACH compliance and SVHC declaration

CUPAL copper-aluminium bimetal composite can be used in electrical and electronic equipment within the framework of both the RoHS (Restriction of Hazardous Substances) and the REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) European chemicals regulations. This article summarises the practical details of compliance.

Material and environmental compliance

CUPAL contains no substances restricted under RoHS or REACH. The base material (AL 99.5 / Werkstoff-Nr. 3.0255 + E1-Cu58 / Werkstoff-Nr. 2.0065) consists of pure metallic elements, with no alloying additions. Both layers are of standard industrial purity (Al: min. 99.5%; Cu: 99.9%).

SVHC-free declaration

The REACH SVHC (Substances of Very High Concern) candidate list may call for a shipment-level declaration, particularly where the CUPAL part is built into a more complex product (switchgear cabinet, charging station, vehicle component). In such cases:

• An SVHC-free declaration can be issued on request, per shipment or tied to a specific project, by our German supplier (WMH Westdeutscher Metall-Handel GmbH).
• The declaration references the SVHC candidate list of chemicals and certifies that CUPAL contains no SVHC substance from the applicable list above the reporting threshold (0.1% w/w).

When should you request the declaration?

It is worth requesting the shipment-level SVHC declaration when:

• you are placing the finished product on the EU market (CE marking, REACH/RoHS internal documentation),
• you have to report the material composition to an OEM customer in the IPC-1752A or a similar component-compliance data-exchange format,
• the material falls within the scope of a public procurement or a bill-of-materials (BOM declaration) audit.

What does the declaration contain?

• Identification of the CUPAL base material (Werkstoff-Nr. 3.0255 + 2.0065).
• A reference to the applicable SVHC candidate list (with the date of issue).
• A reference to the ISO 9001:2015 certified quality management system of the supplier (WMH).
• The shipment lot/charge identifier, where tied to a specific batch.
