Product Description
Copper Expanded Metal Foils for Wind Turbine Lightning Strike Protection
We have developed a large range of products and offer expanded metal in brass, phosphor bronze, and copper in various sizes, widths, and meshes. Copper expanded metal is used for Wind Turbine Lightning Strike Protection, filter industrial applications, (petrol)chemical industry, aeronautics, automotive and electrochemical field, where their superior strength and versatile size lead to improved performance at a minimal cost.
Aluminum mesh material as per ASTM B373 99.45% Aluminum
Copper mesh material as per ASTM B152 99.9% Copper
Micro expanded metal (copper or aluminum expanded metal foil) has excellent electrical conductivity. Insert the aluminum/copper expanded metal into composite material and form the material into blades to supply a lightweight shielding solutionto wind energy. Besides, it is one of the ideal materials for electromagnetic compatibility of composite material. When struck by lightning, it can play a critical electrical conductivity to effectively dissipate the destruction of lightning strike, protect the carbon fiber layer and prolong the service life.

Copper Expanded Metal Foils Advantages
- Outstanding mechanical strength (Anti-ravel and Flexible)
- Micro expanded metal is a cost-effective alternative to perforated metal - especially when using high-value raw materials
- High conductivity, apertures reach conductivity of 200,000 amps
- Good lightning protection and electromagnetic interference prevention
- Excellent shielding and heat transfer performance
- Single structure, formed all by one piece, eliminating the possibility of mesh breakage and sudden resistance fluctuations
- Uniform openings and thickness, making the surface smooth and adhesives easier to penetrate
- Flexibility in design and weight according to different structures and requirements
- Precision expanded metal mesh product for specialist industry needs
