Research on the Effect of Rolling Processing Rate on the Structure and Properties of C19400 Alloy
High precision lead frame materials have strict requirements for the performance of copper alloys,requiring both high hardness and high conductivity.The rolling processing rate and aging directly affect the material's performance.In order to explore suitable processing techniques,the effects in the microstructure and properties of C19400 under different rolling processing rates and aging processes were studied.It was found that under experimental conditions,the alloy had high hardness and conductivity after a secondary cold rolling aging temperature at 400℃and aging for 8 hours.The alloy also had high resistance to softening and low production costs.Therefore,priority should be given to developing processing techniques.
