Latest Patents

Zhongling Zhang holds a patent for an oxide dispersion-strengthened alloy (ODS) and a method for producing lead-free and free-cutting brass. The composition of this brass includes 52.0%-90.0% copper, 0.001%-0.99% phosphorus, 0.15%-0.70% tin, 0.25%-3.0% manganese, 0.15%-0.90% aluminum, 0.10%-1.5% nickel, 0.191%-0.90% oxygen, and 0.06%-0.80% carbon. The ratio of aluminum to oxygen does not exceed 27:24, with the balance being zinc and inevitable impurities, while lead content is limited to no more than 0.08%. The production process involves a powder metallurgy method, where brass powder, copper oxide powder, and graphite micro powder are mixed, followed by the addition of a forming agent, compression molding, and sintering.
