Our copper-nickel-tin alloy products (plate, coil) comply with EU RoHS Directive. We use a voluntary marking which shows conformance to RoHS on our material certificate and in the catalog of products. Conformance has been confirmed with internal standards.
In 2016, NGK launched mass production of "copper-nickel-tin products" in addition to "beryllium copper products". We will realize the supply of copper-nickel-tin products that meet the needs of the world market by preparing the integrated production system from casting through slitting.
Based on our production technology and strict quality control cultivated from our history of beryllium copper production, we will supply copper-nickel-tin products that meet diversified. customer needs, and contribute to the high reliability and miniaturization of parts.
Our copper-nickel-tin alloy, strengthend by spinodal decomposition, is high performance copper alloy which has excellent characteristics such as high strength, heat resistance and wear resistance comparable to beryllium copper alloy.
NGK never uses conflict minerals for tin plating on beryllium copper products or in copper-nickel-tin products according to our basic purchasing policy "NGK Group's Supply-Chain CSR Guideline" as attached below.
