نحاس C14500

Copper C14500, commonly known as Tellurium Copper, is the premier choice for precision-turned copper components. By adding a small percentage of tellurium, the alloy achieves a phenomenal machinability rating of 85%, allowing for high-speed automated production that is impossible with pure copper. Despite this increased efficiency, C14500 retains approximately 93% of the electrical and thermal conductivity of pure copper. At Jucheng Precision, we leverage C14500 to provide our clients with high-volume, high-precision electrical connectors, welding nozzles, and gas fittings. Our Swiss-style CNC lathes excel at producing complex C14500 parts with superior surface finishes and tight tolerances at the most competitive unit prices.

C14500 Machining Capabilities

القدرة الوصف الفني ميزة Jucheng
الخراطة السويسرية عالية السرعة C14500 has a machinability rating of 85%, allowing for extremely high surface speeds and feeds comparable to brass. Our Swiss-style lathes produce intricate C14500 pins and sockets at massive scales with cycle times up to 4x faster than pure copper.
Precision Drilling & Reaming Small-diameter deep hole drilling for gas nozzles without tool wandering or material gumming. We achieve perfect concentricity and smooth internal bore finishes (Ra 0.4μm) for critical fluid and gas flow components.
Clean Threading Generating sharp internal and external threads with single-point tools or taps without burrs. Ensures perfect mating and gas-tight seals for welding torches and high-frequency electrical connectors.
Automated Mass Production Utilizing bar-fed CNC centers for continuous production of Tellurium copper hardware. Offers the most cost-effective copper solution for high-volume orders (10,000+ pieces) due to extended tool life and speed.

Fabrication Guidelines for C14500 Tellurium Copper

Superior Chip Control:
The addition of Tellurium creates a “short-chip” copper. Unlike pure copper, it does not produce long, stringy nests. نصيحة: This allows for unattended automated machining and high-speed production runs.

Conductivity Trade-off:
C14500 maintains ~93% IACS electrical conductivity. نصيحة: While slightly lower than pure copper, it is significantly better than brass or bronze, making it the perfect compromise for electrical hardware.

Tool Selection:
While HSS can work, we utilize premium carbide tooling to take full advantage of C14500’s speed. نصيحة: The material is non-abrasive, resulting in extremely long tool life compared to other metals.

Joining Methods:
C14500 is excellent for brazing and soldering. However, like most lead or tellurium-added alloys, it is less suited for high-energy arc welding due to potential porosity.
