2000PCS 10mm 1.2mm Thick Heavy Duty 16 Gauge Stainless Steel Jump Rings, Unwelded Metal Round Strong Craft O Ring for Necklace Bracelet Keychain Chainmail Jewelry Making

Important Purchase Notes 1. These rings are stamped and cut rings, not saw-cut rings. The palm display images show the cutting quality; all products are polished and feature the natural color of stainless steel. 2. The rings are made of half-hard 304 stainless steel wire. Hardness ranking: Stainless Steel > Iron > Brass > Aluminum Alloy. As stainless steel is the hardest among common ring materials, you need to use large‑size pliers to open and close larger rings easily. 3. Our product dimensions are expressed as outer diameter × wire diameter. The wire gauge uses American Wire Gauge AWG – please avoid confusing it with British Standard Wire Gauge SWG. 4. Our products can pass 304 stainless steel test solution testing and XRF spectrometer composition testing. Stainless Steel Identification Methods: Magnet Adsorption Test (Not Accurate, Not Recommended): 201/202/303/304/316 stainless steel is non-magnetic or weakly magnetic. Only when a product shows strong magnetism can it be preliminarily judged as non-201/202/303/304/316 stainless steel. 304/316 Stainless Steel Test Solution (Moderately Accurate, Moderate Cost, Recommended): Different grades of stainless steel have different compositions. They react with the test solution and show different colors, so you can identify the stainless steel grade by color change. XRF Spectrometer Composition Analysis (Highly Accurate, High Cost, Recommended): It can accurately distinguish different grades of stainless steel through professional composition analysis.
