What is the difference between titanium steel and titanium alloy?
titanium steel
The name titanium steel is not a standard academic name, but a commercial name. Titanium steel is also called 316L stainless steel because the anti-corrosion, acid, and alkali resistance of 316L stainless steel is better than that of ordinary stainless steel. Titanium steel does not contain titanium, and its main component is still iron. This commercial name is to distinguish it from other stainless steels and gain higher value when used as jewelry. However, there are currently many so-called titanium steel jewelry in China, which generally contain a small amount of nickel. Nickel can cause allergies and inflammation in a small number of people.
Titanium alloy
An alloy formed by titanium and other metals and non-metals. A certain treasure is usually called "titanium" if it sounds nicer. These metals and non-metals such as aluminum, platinum, vanadium, chromium, iron, aluminum, tin, oxygen, carbon, etc. Taking the most commonly used TC4 ferroalloy as an example, its titanium content is 90%, aluminum 6%, and vanadium 4%, so it is also called titanium 6 aluminum 4 vanadium. TC4 titanium alloy is the earliest developed and most widely used titanium alloy in the world, and it is also the earliest titanium alloy used in medical treatment. It has high anti-corrosion properties, is stronger than pure titanium, has good toughness, and is relatively easy to process and weld, so its overall performance is excellent, and it does not cause allergies like pure titanium. The safest standard for titanium alloy jewelry is F136, which is ASTMF136 that complies with the standards of the American Society for Testing and Materials International (ASTM). GR23 or G23, which sellers often refer to, is a grade under it.
Pure titanium
The important point is that there is no pure titanium jewelry in the true sense. They are all titanium alloys. The highest titanium content is freshly made titanium sponge, but titanium is too active and easily reacts with oxygen, nitrogen, hydrogen, etc. in the air when exposed to air, so it is almost impossible to achieve 100% purity. Generally speaking, if the titanium content is higher than 95%, it is generally made of industrial pure titanium. The higher the titanium content, the softer it is, but the tougher it is.
How to distinguish between titanium alloy jewelry and titanium steel jewelry?
1. Weight method: Pure titanium jewelry is nearly half lighter than titanium steel jewelry!
2. Fire method: As the saying goes, real gold is not afraid of fire. When pure titanium jewelry is heated in fire, it will turn into gold or blue, and titanium steel jewelry will turn gray!
3. Magnetic attraction method: It can be identified by magnets. Pure titanium jewelry will not be attracted by magnets, but titanium steel jewelry will be attracted by magnets!
