Problems solved by technology

[0007] Traditional copper products contain a certain proportion of lead content. Copper containers will lead to lead contamination of contact food and water sources, leading to lead poisoning and related physical damage to people in contact with them. At the same time, they cannot meet the increasingly high environmental protection requirements. Require

Description

technical field [0001] The invention relates to copper materials, in particular to a novel white copper and a processing method thereof. Background technique [0002] China's manufacturing industry has made great progress in the past three decades, introducing a large number of advanced equipment and manufacturing processes. In order to meet the needs of domestic and international markets, China's manufacturing industry has gradually transformed from labor-intensive manufacturing of low-end products to High value-added products for mid-to-high-end precision manufacturing. The special cupronickel materials required by the medium and high-end precision manufacturing industry have always been the weakness of China's manufacturing industry. European and American countries have always adopted patent intellectual property protection and production technical barriers to limit imports to China in the field of high-end cupronickel manufacturing components and processes. [0003] As ...
