Materials

Handa EMI Shielding Springs(canted coil spring) contact elements are precision manufactured from high quality copper alloy and stainless steel base materials, selected for their excellent combination of mechanical and electrical properties. Our copper alloys are sufficiently conductive to be used in many applications without the need for plating. Our stainless steel material offers higher specific compression force values than copper for the same spring size and can be enhanced by plating with more conductive metals.

  • Stainless steel
  • MP35N
  • Elgiloy
  • Other
  • Beryllium copper alloy
  • Platinum Iridium
  • Hastelloy
  • Zirconium Copper
  • Titanium
  • Inconel

Plating

Canted coil spring plating is a crucial process that enhances the performance and longevity of canted coil springs. By applying a protective coating, it increases resistance to corrosion, wear, and electrical conductivity. This process is vital for ensuring reliable connections in demanding applications, such as aerospace, medical devices, and industrial machinery.

Optimizing canted coil spring plating involves selecting the appropriate plating material, such as gold, silver, or nickel, to meet specific application needs. Proper plating enhances the spring’s durability and conductivity, leading to improved performance and extended service life. Trust our expert plating services for superior quality and precision in every application.
