Characteristics
CAMK14500 is classified as a free-machining copper. The copper telluride precipitations in the microstructure affects the cutting chips into short pieces, thus enabling a much higher machining speed than with pure copper.
1. CAMK14500 has a machinability rating scale of 85%, compared to pure copper of 20%, thus longer tool life.
2. The high conductivity of tellurium copper makes it a suitable material for electrical applications.
Application
CAMK14500 is used where high-insertion loads or high cycles are required.such as socket connectors for high-voltage power sources, welding tips, plumbing fittings, soldering coppers, transistor bases, furnace brazing, motor part, electrical switches on power semiconductors, transformer & circuit breaker terminals, fasteners, etc.
Advantage
1. We actively respond to any questions from customers and provide shorter delivery times. If customers have urgent needs, we will fully cooperate.
2. We focus on controlling the production process so that the performance of each batch is as consistent as possible and the product quality is excellent.
3. We cooperate with the best domestic freight forwarders to provide customers with sea, rail and air transportation and combined transportation solutions, and have plans for transportation difficulties caused by natural disasters, epidemics, wars and other factors.
