CuNi44 Bright 420 MPA 50mm Soft Heating Nickel Copper Rod OEM

A "Bright 420 MPa 50mm Soft CuNi44 Heating Nickel Copper Rod" combines several specific features of the CuNi44 alloy with particular mechanical and physical properties. Let's break down these features:

Composition and General Properties:

• CuNi44 (Constantan):

• Approximately 44% nickel and 56% copper.

• Known for high electrical resistivity and a low temperature coefficient of resistance (TCR).

Specific Features:

1. Bright Finish:

• Indicates a polished surface, often achieved through processes like bright annealing or electro-polishing. This finish can be important for aesthetic reasons or for specific functional requirements where surface smoothness is crucial.

2. 420 MPa:

• This refers to the tensile strength of the rod. A tensile strength of 420 MPa indicates the rod can withstand a significant amount of stress before deforming or breaking, which is crucial in many structural and functional applications.

3. 50mm Dimension:

• The rod's diameter is 50mm. This size suggests it is used in applications requiring substantial material volume, likely providing substantial mechanical strength or thermal capacity.

4. Soft Condition:

• The term "soft" indicates that the rod has been annealed, a heat treatment process that makes the material more ductile and less prone to cracking during forming. This enhances its workability, making it easier to bend or shape without breaking.

  
  

Applications:

Given these properties, a "Bright 420 MPa 50mm Soft CuNi44 Heating Nickel Copper Rod" would be well-suited for applications such as:

1. Heating Element s:

• Used in industrial heating applications where consistent and reliable heating is required.

• The high resistivity and stable resistance of CuNi44 make it ideal for use in heating elements.

2. Thermal Conductivity:

• Effective in applications where good thermal conductivity is needed alongside electrical resistance.

• The bright finish can help in applications where a clean, non-oxidized surface is beneficial.

3. Electrical Applications:

• Suitable for manufacturing precision resistors, especially where stable resistance over a range of temperatures is critical.

• Used in high-precision electrical instruments where stability and accuracy are paramount.

4. Mechanical Applications:

• The 50mm rod's strength and ductility make it useful in mechanical settings that require durable and reliable material, like certain structural components in harsh environments.

5. Laboratory and Experimental Uses:

• Often used in research settings where specific material properties are necessary for experiments and prototype development.

Overall, this specific form of CuNi44 is versatile, combining electrical resistivity, mechanical strength, and thermal stability, making it suitable for a range of specialized applications.
