Research conducted by the DMM Advisory Group found that miniaturization of select copper products increased slightly in 2019. This change was due to the increased use of new technologies and product designs offering opportunities for cost reduction without the need for substitution of copper. The findings, commissioned by the International Copper Association (ICA) found the increase in miniaturization is led by new motor designs, smaller diameter copper tubes and material reduction in copper-rolled products (plate, sheet, strip and foil) and alloy products.
Miniaturization is a key driver of innovation in consumer electronics, leading to new sources of copper demand. The evolving miniaturization space has led to new electronic devices such as smaller laptops, smartphones and tablets, all of which require copper.
