The price of copper rose by 50% in 2020, from 5,000$/Tn in January to 7,300$ in December, and is still rising, expecting to reach 11,000$ this year. This rise continues to hurt the manufacturing industry, forcing it to increase the price of its products and reduce margins. In addition, aluminum, like steel, has doubled in cost, which has a major impact on the refrigeration industry that uses these materials intensively.
