MicroGrid® precision expanded foils from Dexmet can be used in a wide variety of applications that require an open area product. A superior alternative to woven wire or perforated products, Dexmet materials can be found in batteries as electrode materials, in aerospace for lightning protection or EMI shielding, or even automobiles for air and hydraulic filtration application. All the materials can be tailored to meet mechanical and electrical performance parameters. Whether it's shielding effectiveness for EMI protection or conductivity for ligtning strike midigation, the infinitely variable process of expanding can be fine tuned to meet specific performance criteria. Expanded foils are available in most ductile metals or we can work with your proprietary materials. Metals we regularly produce include: aluminum, copper, nickel, cold rolled steel, stainless steel (302, 316, 409, 430), titanium, brass, zinc, Monel™.
- One-piece, single-unit structure
- Eliminates unraveling and contact resistance of woven mesh
- Superior shielding, electrical and heat transfer properties
- Wide range of sizes, patterns, angles and materials
- Specialized process variations, such as flattening, pulling, and annealing available
Dexmet's typical standard expanded metal range can have diamond mesh sizes from .031" to .500″ (LWD). Open Area can range from as low as 30% to as high as 95%. The wide range in open areas can facilitate the use in laminations or coatings with a variety of other materials which may require a material to expand, contract or flex. Applications with unique parameters and requirments are perfect for expanded materials. Dexmet’s extensive manufacturing resources can accommodate many process variations for metal materials in a range of finished thicknesses.
