Specifications Material: Copper, purity 99.9% Dimensions: Width 300 mm × Length 300 mm Thickness options (7 choices): 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.8 mm How this product solves problems Ensures consistent electrical paths and low-resistance connections for circuits and grounding systems. Provides an efficient thermal path for heat spreading or dissipation in compact assemblies. Offers predictable mechanical and processing behavior so parts can be fabricated to tight tolerances without material surprises. Compatibility and performance notes Suitable for use where high electrical and thermal conductivity are required. Sized to fit common prototyping and small-panel applications; cut-to-fit for custom enclosures and assemblies. Material purity supports stable long-term performance in electrical, thermal, and general fabrication roles. Practical applications Electronics prototyping and small heat spreaders: use as a thermal interface or copper pad to move heat away from components. EMI/RFI shielding and grounding: line small enclosures or backplanes to improve electromagnetic compatibility and provide reliable grounding paths. Custom electrical contacts, busbars, or craft/metalwork: thin, uniform sheets for precise forming, trimming, and integration into assemblies. Ordering tips Select the thickness that matches your bending, conductivity, and mechanical rigidity needs; seven thicknesses available between 0.1 mm and 0.8 mm. Each sheet measures 300 mm × 300 mm for straightforward integration into standard fixtures and work areas.
