High elasticity, high conductivity, and good corrosion resistance beryllium copper spring, beryllium copper spring, beryllium copper sealing strip

The shrapnel provided by our company with electromagnetic wave shielding effect is made of beryllium copper alloy and can be used to seal two connections

The gap between the contact surfaces provides a high EMI shielding effect, while the beryllium copper spring provides a high shielding effect for the shielding cover

The closure required for the shielding cover is extremely low, and the beryllium copper spring has high relaxation resistance and excellent wear resistance. this

The shrapnel can be treated with various metal plating options to ensure its compatibility with any contact surface

But it will not burn or be affected by radiation. Based on these advantages, the design of computers and electrical products

Cheng Shi regards beryllium copper shrapnel as an ideal electromagnetic wave shielding material.

Beryllium copper spring has high elasticity, high conductivity, and good corrosion resistance, making it the most ideal EMI shielding material for a wide frequency range,

Widely used for shielding various communication electronic devices. The shielding spring has various structural forms and can be used in various shielding rooms/cabin doors/

Chassis/cover plate/printed circuit board plug-in board/integrated circuit shielding and other occasions. Flexible and diverse installation methods: card mounted, adhesive （3M

Pressure sensitive adhesive, riveting type, etc.
