Details
Pins are made of tin, copper and lead C19160 pins and jacks. Tin, copper and lead are made of C19160 pins and jacks. There are many choices for pin and jack materials in more usage scenarios. C19160 belongs to the American standard lead-nickel-copper rod (lead-copper-lead-nickel). Copper C19160 and C19140 are unique precipitation hardening alloys containing copper, lead, nickel and phosphorus. The nickel and phosphorus in the alloy combine to form nickel phosphate and can be retained by quenching. Subsequent aging will remove the solid solution from the solid solution in a highly dispersed manner. Precipitates nickel phosphate, resulting in a significant hardening and strengthening effect with excellent stress relaxation properties. C19160 is nominally composed of 97.8% copper, 1.0% lead, 1.0% nickel and 0.2% phosphorus, while C19140 is nominally composed of Composed of 98.3% copper, 0.5% lead, 1.0% nickel and 0.2% phosphorus. With their high corrosion resistance, high tensile strength and yield strength, high electrical conductivity, they can process pins and sockets of a certain strength. Good Formability, processability, ease of plating and high bending strength are also well-known properties of this alloy, allowing them to be used wherever high strength, corrosion-resistant alloys are required, primarily for electrical contacts, connector pins, pin jacks .
