The price of Platinum Mesh is primarily driven by purity (typically 99.9% or 99.95%), wire diameter, and mesh count (apertures per inch). For laboratory and industrial catalysts, the surface area-to-weight ratio is critical. Buyers should specify the weaving method (plain, twill, or knitted) as it affects structural integrity. Ensure the supplier provides a Material Analysis Report (MAR) or a Spectroscopic Analysis to verify the precious metal content, as even a 0.1% deviation significantly impacts the valuation.
