“Stainless steel”, “titanium steel” and “alloy” are used loosely in jewellery listings, and the words hide the only question that matters: what is on the surface, and how fast does it come off? This guide separates the four materials you will actually meet and gives a test for each that you can run at home.<\/p>\n

The four materials behind most low-cost jewellery<\/h2>\n\n\n\n\n\n\n\n\n
Label on the listing<\/th>\nWhat it usually is<\/th>\nWhat wears first<\/th>\n<\/tr>\n<\/thead>\n
Stainless steel (304 \/ 316L)<\/td>\nIron-chromium alloy; 316L adds molybdenum for corrosion resistance<\/td>\nNothing structural; scratches show, colour does not flake<\/td>\n<\/tr>\n
“Titanium steel”<\/td>\nMarketing term \u2014 almost always stainless steel, not titanium<\/td>\nSame as stainless, unless plated<\/td>\n<\/tr>\n
Zinc or copper alloy<\/td>\nCast base metal, cheap to shape into detailed designs<\/td>\nThe plating, then the base metal (pitting, green skin)<\/td>\n<\/tr>\n
Plated (gold \/ rose gold \/ silver colour)<\/td>\nA thin layer \u2014 often 0.03\u20130.5 \u00b5m \u2014 over brass, zinc or steel<\/td>\nThe plating at contact points, in weeks to months<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Why “titanium steel” is a translation artefact<\/h2>\n

In Chinese sourcing documents the phrase \u949b\u94a2 (titanium steel) is a trade name for 316L stainless steel. Titanium metal is a different element with roughly half the density and far lower thermal conductivity. If a listing says titanium and quotes a price under about $15 with a heavy feel, it is steel. Ask for the grade (304 or 316L) rather than the marketing name \u2014 a supplier who can name the grade usually knows what they are shipping.<\/p>\n

Nickel is the real allergy question<\/h2>\n

Stainless steel contains nickel bound inside the alloy; the risk comes from nickel release<\/em> at the surface, which is what the EU’s REACH entry on nickel release limits for items in prolonged skin contact. 316L releases less than 304 because of its molybdenum content, which is why surgical steel is 316L and not 304. Plated brass is the bigger problem: once the plating wears through at the inside of a ring or the back of an earring, the base metal is in direct contact with skin.<\/p>\n

Three tests you can run<\/h2>\n
    \n
  1. Magnet test.<\/strong> 304 and 316L are weakly magnetic or non-magnetic depending on cold-working; a strong pull usually means a plated steel core, no pull means either true 316L or a non-ferrous alloy. It narrows the field, it does not identify the grade.<\/li>\n
  2. Rub test.<\/strong> Rub the inside of the band with a white cloth and a drop of alcohol. Colour on the cloth means a coating, not solid metal.<\/li>\n
  3. Weight and warmth.<\/strong> Titanium feels noticeably lighter and warmer to the touch than steel of the same size. A “titanium” bracelet that feels like steel is steel.<\/li>\n<\/ol>\n

    What the Chinese standard actually regulates<\/h2>\n

    GB 11887-2012 covers precious-metal jewellery purity and marking \u2014 it governs what may be called gold, silver or platinum, and what must be stamped. It does not<\/strong> certify “titanium steel” as titanium, because that term is not a precious-metal designation at all. If a seller claims a standard number, check that the number belongs to the material being sold.<\/p>\n

    How to make any of them last longer<\/h2>\n
