When sourcing or manufacturing jewelry cleaning and polishing products on Alibaba.com, understanding surface finish specifications is critical for meeting buyer expectations. The term "polished surface" encompasses multiple grades, each with distinct technical requirements and applications. For B2B suppliers in Southeast Asia looking to sell on Alibaba.com, mastering these specifications can differentiate your products in a competitive marketplace.
Surface roughness is measured using the Ra (Roughness Average) parameter, which quantifies the microscopic peaks and valleys on a material's surface. For jewelry polishing cloths, the effective Ra value depends on both the fiber material and the manufacturing process. Premium microfiber cloths designed for mirror finishes typically achieve effective Ra values below 0.1μm when used with appropriate polishing compounds.
Surface Finish Comparison for Jewelry Polishing Applications
| Finish Type | Ra Value Range | Typical Applications | Material Compatibility | B2B Price Tier |
|---|---|---|---|---|
| Mirror Polish | Ra<0.1μm (4μin) | High-end watches, precious metals, gemstones | Gold, silver, platinum, ceramic | Premium |
| Satin Finish | Ra 0.4-0.8μm | Everyday jewelry, stainless steel accessories | Stainless steel, brass, copper | Mid-Range |
| Brushed Finish | Ra 0.8-1.6μm | Costume jewelry, fashion accessories | Base metals, plated items | Economy |
| Standard Polish | Grit 150-400 | General cleaning, maintenance | All metal types | Entry-Level |
