Anping Xinye Metal Wire Mesh Products Co., Ltd, based in the heart of China's wire mesh industry in Hengshui, Hebei, brings you a precision-engineered 0.3mm Thick Copper Expanded Metal with a 1/4" diamond pattern in a convenient 12" x 24" sheet. This product is specifically designed for EMI shielding applications, offering excellent conductivity and reliable electromagnetic interference protection. Our factory combines decades of metal mesh expertise with modern manufacturing techniques to deliver consistent quality and tight tolerances. Whether you are prototyping electronic enclosures or building custom shielding panels, this copper expanded metal sheet provides an effective and cost-efficient solution.
Product Features & Technical Specifications
- Precision Thickness: 0.3mm (0.012 inch) – thin enough for lightweight applications yet durable enough for repeated handling.
- Diamond Pattern: 1/4 inch (6.35 mm) diamond opening provides a balanced combination of open area and structural integrity.
- Standard Sheet Size: 12 inches (304.8 mm) x 24 inches (609.6 mm) – ready to use for small to medium projects.
- Material Purity: High-grade copper with excellent electrical conductivity (≥58 MS/m) for superior EMI shielding effectiveness.
- Expandable Mesh: The expanded metal manufacturing process creates a continuous, slip-resistant mesh without welded joints, enhancing strength and flexibility.
- Versatile Application: Ideal for RFI/EMI gaskets, shielding cabinets, ventilation panels, and grounding grids.
- Easy to Cut & Form: Can be trimmed with standard tin snips or shears to fit custom dimensions.

Key Advantages for Your Application
- Superior Conductivity: Copper offers the highest electrical conductivity among common metals, ensuring low impedance grounding paths and effective attenuation of electromagnetic fields.
- Cost-Effective Shielding: Compared to solid copper sheets or expensive shielding foams, expanded metal delivers comparable performance at a fraction of the cost.
- Lightweight & Flexible: The 0.3mm thickness and open structure keep the product lightweight (less than 0.2 kg per sheet) while remaining easy to bend or contour around enclosures.
- Ventilation & Visibility: The diamond openings allow airflow and light passage, making it suitable for shielded ventilation panels or viewing windows without compromising electromagnetic integrity.
- No Sharp Edges: Our expanded metal is deburred and flattened to minimize sharp edges, improving handling safety and reducing the risk of damage to adjacent components.
- Customizable: We can supply sheets in other sizes, thicknesses, or materials (e.g., brass, aluminum, steel) upon request. Contact us for bulk orders or custom dimensions.

Frequently Asked Questions (FAQ)
-
Q: Can this copper expanded metal be used for gaskets in high-frequency applications?
A: Yes, the 0.3mm copper expanded metal is suitable for RFI/EMI gaskets in frequencies up to several GHz, provided proper compression and contact with a conductive mating surface. The diamond pattern offers multiple contact points that enhance shielding effectiveness. -
Q: Is the sheet flat or does it have a curved profile?
A: Our standard expanded metal sheets are flattened during production to achieve a relatively flat surface. However, due to the expansion process, some slight natural bowing may exist. For critical flatness, we recommend using a press or roller to flatten after cutting. -
Q: What is the open area percentage? Does it affect shielding performance?
A: The approximate open area is 55-60%. Higher open area reduces weight and improves airflow, but may slightly lower shielding effectiveness at very high frequencies. For most general EMI shielding purposes, the balance is adequate. -
Q: Can I order smaller quantities or samples before bulk purchase?
A: Absolutely. We accept single-sheet orders for prototyping and testing. Contact our sales team for sample pricing and availability. -
Q: How should I cut this expanded metal sheet?
A: Use tin snips, aviation shears, or a fine-toothed hacksaw. For cleaner edges, you can also use a grinder with a cutting wheel. Always wear protective gloves and eyewear. -
Q: Does the copper tarnish over time? How can I protect it?
A: Copper naturally develops a patina (oxidation) over time, which may slightly increase surface resistance. For applications requiring long-term conductivity, consider applying a clear conductive coating or using the product in a dry environment. Alternatively, you can request a tin-plated version. -
Q: What is the typical lead time for orders?
A: For standard 12" x 24" sheets, we maintain stock and can ship within 3-5 business days. Larger quantities or custom sizes may require 7-15 days depending on production schedule. -
Q: Can this material be soldered or welded?
A: Yes, copper is easily soldered with standard electrical solder and flux. Welding is possible but may require special techniques due to the thin strand. For most applications, mechanical compression or conductive adhesive bonding is recommended.
