The Tricks In The Copper Terminal Block Market: Low-purity Recycled Copper Is Passed Off As High-purity Copper.

Some supply chain participants are exploiting market demand for high-purity copper by including insufficiently refined recycled copper terminal block copper in their high-end product lines. This leads downstream companies to discover deviations in the copper distribution block copper composition from the nominal value during material acceptance. Standardized copper classification systems are the internationally accepted quality assessment basis in the metal recycling industry, and high-purity copper has significantly different pricing and uses in the market.

In the copper terminal strip copper manufacturing process, welding and contact performance are also affected by the condition of the raw materials. Solder residues, oxide films, and impurities from the production process all affect the electrical bonding and mechanical strength of the final product.
