RoHS 2.0 limits the toxic lead content of general materials to less than 0.1%. The Department of Health and Human Services (DHHS), Environmental Protection Agency (EPA) and International Agency for Research on Cancer (IARC) have determined that lead is a carcinogen. Exposure to a high-lead environment will cause anemia, weakness, and damage to the liver and brain. Higher levels can cause death. Since lead slag, lead vapor, and lead dust produced during refining, melting and casting, heat treatment, machining, and grinding processes are harmful to health and the environment, the use of lead-containing copper alloy products is equivalent to contributing to the lead pollution disaster in the upstream, midstream and downstream. Such use will affect the conscience of a company. Although RoHS has extended the exemption for high-lead copper alloy C36000 (Cu-Zn-Pb) for machinery on July 1, 2021, it does not mean that the use of lead-containing products is justified. If lead-free copper alloy products are available on the market and meet the required functions, conscientious companies should be the first to use lead-free products. The current ban on lead-containing products in hardware and solder is a reflection of this trend. Therefore, the wear-resistant entropy alloy EM-12501 contains no lead at all, and is a revolutionary high-performance material that complies with the world’s environmental protection requirements.
