Product Description

Product Description

 

Introduction

C7521 is a copper alloy, also known as nickel silver or nickel brass, composed primarily of copper, nickel, and zinc. It's known for its silvery appearance, good mechanical properties, and excellent corrosion resistance. C7521 is often used in applications requiring both a silver-like aesthetic and durability. 

Key Characteristics and Applications:

• Composition: C7521 typically consists of copper, nickel (around 18%), and zinc. 
   
• Appearance: It has a silvery-white, shiny appearance, resembling silver, but typically does not contain actual silver unless plated. 
   
• Good Formability: C7521 is known for its ability to be easily formed, drawn, and shaped. 
   
• Corrosion Resistance: It offers good resistance to corrosion and tarnishing, making it suitable for various environments. 
   
• Applications:
  • Electronic Components: Used in liquid crystal oscillator housings, connectors, and shielding due to its dimensional stability and non-magnetic properties. 
     
  • Medical Devices: Employed in surgical tools, dental instruments, and medical connectors where corrosion resistance and biocompatibility are important. 
     
  • Precision Instruments: Used in potentiometer sliders and contacts due to its electrical conductivity and wear resistance. 
     
  • Other Uses: Also found in silverware, jewelry, glasses, and various other applications where a silver-like appearance and durability are desired. 
     
• Mechanical Properties: C7521 can exhibit good fatigue resistance, high strength, and excellent elasticity. 
   
• Standards: C7521 is specified under various standards, including JIS, C7521 (H3110), and UNS/CDA C75200.
