C19025
"C19025 developed by Dowa Metals as Alloy NB109 to meet the increasing requirements of current carrying capacity, stiffness, formability, and service temperature survivability now being demanded by the automotive and electronic industries. Its high strength, stress relaxation resistance, and 40% IACS conductivity makes the alloy exceptional for small and demanding automotive connector applications."
C194
"Developed by Olin Brass in 1964 the alloy continues to be used for a variety of applications including automotive and electrical connectors, semiconductor leadframes, sockets, and mass terminations. C194 combines good electrical and thermal conductivity, strength, solderability, and plateability."
C197
"Alloy C197 is a dilute alloy of copper, iron, phosphorus, and magnesium. Optimized process control results in improved conductivity of 80% IACS, as compared to alloy C194 at 60% IACS with equivalent strength."

C19720

"Olin Brass C19720 is a dispersion strengthened, high conductivity copper alloy with mechanical and physical properties identical to Olin Brass C197. C19720 was developed by modifying the chemistry of C197 in order to produce an alloy with improved reliability at elevated temperatures. C19720 will maintain at least 70% of its initial stress after exposure to 125°C for 3000 hours and push 150°C for 1000 hours. C19720 is a fit for active contact applications in under hood automotive power distribution."

C210
"Gilding Metal is widely used where resistance to corrosion is important and in applications such as coining where high malleability permits the production of sharp impressions. It is used for deep-drawn products such as bullet jackets; and its relatively high conductivity makes it valuable for electrical applications where higher strength than that of copper is desired."
C260
"The "work-horse" of the copper alloys, cost effective cartridge brass can be readily formed into thousands of different parts and has the strength to perform many useful functions. With a warm yellow color, it can be deep drawn with more facility than any other commercial metal."
