Cnc Machining Tellurium Copper C14500


Tellurium Copper C14500 is a copper alloy that contains a small addition of tellurium (Te) as an alloying element. It is also known as tellurium-bearing copper or tellurium bronze.Tellurium acts as a free-machining element in copper, enhancing the alloy’s machinability. It helps in the formation of finely divided chips during machining, reduces tool wear, and improves surface finish.The presence of tellurium contributes to increased strength and hardness compared to pure copper.

Top Tellurium Copper C145 Machined Parts & Case Studies


The Chemical Composition Of Tellurium Copper C145


Tellurium-bearing copper or tellurium bronze, typically includes the following elements:

  • Copper (Cu): Approximately 99.5% minimum
  • Tellurium (Te): Typically 0.4% to 0.7%
  • Other Impurities: Including small amounts of phosphorus (P), sulfur (S), and traces of other elements

The addition of tellurium to copper in Tellurium Copper C14500 enhances its machinability while providing improved strength and hardness compared to pure copper. The small amounts of impurities present in the alloy have a minor influence on its mechanical and electrical properties.

Mechanical Properties Of Tellurium Copper C145


Below are typical mechanical properties for annealed Tellurium Copper C14500:

  • Tensile Strength: 290 MPa (42,000 psi) minimum
  • Yield Strength: 170 MPa (25,000 psi) minimum
  • Elongation: 12% minimum
  • Hardness: 80 HRB (Rockwell B) minimum

These values represent the general mechanical properties for annealed Tellurium Copper C14500. It is important to note that these properties can change with different temper conditions such as half-hard, hard-drawn, or fully annealed copper.

Tellurium Copper C14500 offers improved strength and hardness compared to pure copper due to the presence of tellurium. Additionally, the alloy retains good electrical conductivity relative to many other materials, making it suitable for applications that require both electrical conductivity and improved machinability.

It’s worth mentioning that the mechanical properties of Tellurium Copper C14500 can be further modified through processes such as cold working, annealing, or heat treatment. These processes can affect properties such as strength, hardness, and elongation, allowing for tailored mechanical properties to suit specific applications.

Heat Treatment Process Of Tellurium Copper C145


Here are two common heat treatment processes used for Tellurium Copper C14500:

  • Annealing: Annealing of Tellurium Copper C14500 can be performed to relieve internal stresses, improve ductility, and enhance the machinability of the material. Annealing is typically carried out by heating the material to a specific temperature range, typically between 450°C and 700°C (840°F to 1300°F), and then slowly cooling it to room temperature. The exact temperature and time parameters may vary depending on the specific requirements and recommendations of the material specification or manufacturer.
  • Stress Relief: Stress relief heat treatment can be applied to reduce residual stresses that may have developed during manufacturing processes such as cold working or machining. This process involves heating the material to a temperature below its recrystallization temperature (around 200°C to 300°C or 390°F to 570°F) and holding it at that temperature for a specific period, followed by slow cooling. Stress relief can help minimize distortion or dimensional changes in the material.
