Tellurium copper alloy 145 (TeCu) is considered a free-machining copper alloy, ideal for parts that require extensive machining, corrosion resistance, or high conductivity. It produces short, clean chips that are easily removable. Tellurium copper machines more quickly and efficiently than pure copper.

Machining copper alloys is considerably easier than machining steels or alumin-ium alloys of the same strength (see Figure 1). This is reflected in the signif- ... in which tellurium, sulphur or lead have been added to the pure copper as chip-breaking alloying elements.

C145 Tellurium Copper (TelCu) has applications in the production of hot forged products, high-speed screw machine products and parts requiring high conductivity, extensive machining, corrosion resistance, copper color, or a combination of these. The addition of

Milling Tellurium Copper (C14500) I am a student running a machine shop for research projects and have mostly dealt with aluminum, so this is new water to me. This is a one-off job that I need to be highly accurate with, and I don't need it done particularly quickly.

Also called tellurium copper, 145 copper contains tellurium, which makes it more machinable than all other copper while maintaining good corrosion resistance and high electrical conductivity. It's often used for transformer and circuit-breaker terminals, welding torch tips, and fasteners.. For technical drawings and 3-D models, click on a part number. ...

The copper telluride precipitations become finely dispersed throughout the matrix and assist in chip breakage into short pieces, thus enabling a much higher machining speed than with pure copper. Copper 145 Tellurium has a machinability rating scale of 85%, compared to pure copper of 20%, thus ensuring longer tool life.

In this work, copper based tellurium metal matrix is produced. Material properties, ultrasonic machining performance and applications of newly synthesized tellurium copper metal matrix is studied.

Tellurium copper is not suited to welding, but it can be welded with gas shielded arc welding or resistance welding. It can be readily soft soldered, silver soldered, or brazed. Tellurium copper can be used as the electrode in electrical discharge machining (EDM) - the alloy is used to replace copper when grinding wheel loading occurs during ...

If you can, try and get hold of some Tellurium Copper (C145). We use this for making all the EDM electrodes for our moulds, and it is a very freecutting copper that is very nice to machine, not gummy at all, and takes a lot of fine detail machining without a problem.

C14500 Tellurium Copper. Considered the best machining of the high-Copper Alloys, this Copper-Tellurium Alloy acquires strength from "Alloying" Tellurium. As with all metals, when reducing the amount of Copper, conductivity dramatically decreases yet strength increases. This copper product is used where high-insertion loads or high cycles ...

Copper-tellurium – CuTeP, Copper-sulphur – CuSP. For electrical and electronic applications requiring extensive machining, copper-tellurium (CuTeP, Te: 0.4-0.7%) and copper-sulphur (CuSP, S: 0.2-0.7%), with machinability indexes of 80% and an IACS of 93-94%, are the ideal choices. They are called free machining coppers. Go to Quick Facts ...
