Finger Stock EMI Gaskets:
Application of BeCu EMI Gaskets
Beryllium Copper -- The Material of Choice
EMI designers know and trust the consistent performance of beryllium copper (BeCu) gaskets. To date, BeCu yields the best electrical spring contact available in this industry. The beryllium copper mills have well established techniques and for decades have produced BeCu alloys for ASTM, SAE, JIS, and DIN specifications.
Leader Tech uses only proven technology in creating beryllium copper springs, contacts and gaskets. Beginning with Alloy 25 (1/4 hard) BeCu we stamp, form, and post heat-treat to a hardness of 340 to 390 DPH. This process is preferred in the EMI shielding industry because it has proven to produce the best electrical spring contacts. Leader Tech BeCu EMI shielding gaskets are some of the most reliable in the industry.
Leader Tech manufactures all of the popular standard styles and sizes of BeCu gaskets. These gaskets operate in spaces from .010 inches up to .500 inches. Using BeCu materials as thin as .002 inch, we also offer many styles as soft gaskets that provide the low compression force needed in many applications. Leader Tech also designs and manufactures custom spring contacts and gaskets.
Metallized cloth-over-foam gaskets are often suggested as replacement for BeCu EMI Gaskets. However, when the basic difference are evaluated BeCu remains the performance leader.
