-88.46%C14500 copper (UNS C14500, tellurium copper) is copper with 0.4–0.7% tellurium and a little phosphorus. The tellurium makes the chip break short, so it machines well, and it still keeps an electrical conductivity of about 93% IACS. That is why it is used for welding contact tips, connectors, terminals, electrodes and turned electrical parts. At PREMSA we CNC turn and mill it from your file, starting at a single part with an instant price.

Custom C14500 parts
What people ask most about C14500 copper parts: what it is, what tellurium copper is, composition, uses, machining, conductivity, magnetism, corrosion, welding, equivalents, price and tolerances.
C14500 copper is chosen for parts that have to carry current and also have holes, threads or fine details: contact tips, connectors, terminals and electrodes.
At PREMSA Industries we machine C14500 with CNC turning and milling from your file, from a prototype to production.
C14500 is chosen when the part has to carry current and have small holes, threads or fine details.
If your drawing doesn’t specify tolerances, we machine to ISO 2768-m (medium). On dimensions you call out —fit diameters, bores, threads and lengths— we can hold ±0.025 mm (±0.001 in), and critical dimensions are checked in inspection.
C14500 is machined with CNC turning, CNC milling, drilling and tapping. The chip breaks short, so long small holes can be peck drilled and fine threads and details come out with a good finish, using sharp tooling and coolant.
Because it carries current and machines well, C14500 is used in many parts made with CNC machining.
C14500 is usually the right choice when the part has to carry current and has small holes, threads or fine details.
