Micro Expanded Metal with Excellent Electrical Properties

Micro expanded metal is a type of special expanded metal with small openings, and it can be made from various alloys such as carbon steel, stainless steel, copper, aluminum, nickel, and titanium. It offers mulitple benefits including ventilation, light transmission, heat dissipation, high electrical conductivity, sound absorption, and filtration protection.

This material is widely used in medical equipment, lightning protection, batteries, renewable energy systems, and electromagnetic shielding applications. In shielding applications, micro expanded metal is especially critical – it effectively resists electromagnetic and radio frequency interference, as well as other forms of electromagnetic radiation, combining both physical and electrical properties to meet diverse shielding requirements.
