Introduction to jewelry materials:

what is titanium steel?

Titanium steel, also known as 316L stainless steel and 316L stainless steel, is actually the same material, but the names of regions and merchants are different. In order to make it more fashionable and technological, merchants call it "titanium steel". In fact, it does not contain "Titanium". The real material is called 316L stainless steel, it has a wide range of uses, its characteristics are strong acid resistance, strong alkali resistance, no discoloration, no allergy, no deformation, hard and bright. It is mostly used in medicine, precious watches, pens, industry and so on. Due to different names from different places,

early 316L stainless steel was used on watches and precious pens of famous fashion brands. Due to the rise of European and American LIERSHERF, it gradually revealed new ideas on decoration design. With its unique metallic luster and material properties of fine steel, it has gradually become the focus of fashion and trendy accessories. The rugged, simple, calm, implicit, enthusiastic and bold style and the cold metal performance have won the love of fashion and young people and white-collar workers. The material is the same from the inside to the outside, and its characteristics are strong acid resistance, strong alkali resistance, no discoloration, no allergy, no deformation, hard and bright. And passed the artificial sweat test, no corrosion, no discoloration, no fading, no allergy. First-class craftsmanship, combined with hard and bright features, can better show personalized and unique style.

With the change of trend, 316L stainless steel accurate die casting technology has been successfully developed and its unique design makes the style more three-dimensional, combining advanced technology into one, injecting a sense of future and technology, fully grasp the fashion pulse and fashion trend, which is different from the special texture of ornament and is deeply loved by taste people.

What is titanium? (Also known as titanium, pure titanium)

titanium was discovered at the end of the 18th century. In 1791, British chemical enthusiast W Gregor found an unknown new element in minerals. 1795german chemist M.H. Clapruus (Klaproth) discovered this element when studying the jinredstone (TiO 2). He named it after the son fo the Earth Titan in Greek mythology (the Chinese translation of its original name, named titanium). In ancient Greece, the spirit of Titan "was a synonym for marching forward bravely, naming titanium to indicate the natural strength of metallic titanium. Titanium (Ti)--- silver gray metal, specific gravity 4.5, melting point 1668°C. Titanium is a very special metal, which is very light in texture, but very tough and corrosion resistant. It will not turn black like silver and will maintain its own tone for life under normal temperature. The melting point of titanium is similar to that of platinum, so it is often used in aerospace and military precision parts. After adding current and chemical treatment, different colors will be produced. Due to the above characteristics of titanium, its unique silver gray tone is highly polished. Mercerized. Matt has a good performance. It is the most suitable jewelry metal except precious metal platinum and gold. It is often used in modern jewelry design abroad and is a popular jewelry material in the world. As for the style design, the simple and clean cutting, high design and low-key avant-garde style are highly praised by young white-collar workers. However, due to the high requirements of titanium processing technology, it is difficult to cast and form titanium with common equipment, and it is difficult to weld it with common tools, so it is difficult to form a production scale. Therefore, it is difficult to see its trace in the domestic jewelry market, which is commonly known as titanium and pure titanium in the market.

What is tungsten steel?

Tungsten steel is another high-tech product pursued by mass buyers after space ceramic. It is used in aerospace science and technology within shuttle and is now converted to civilian use. In fact, tungsten steel has a lot to be loved by consumers. This material is different from the material used for ordinary watches. Its hardness is close to that of natural diamonds and its hardness (HRA is 89-91 degrees, also known as hardness 9, Diamond hardness is 10), wear-resistant and scratch-free (no wear), no deformation, corrosion-resistant and rust-free, non-allergic to the skin, the surface is as bright as a mirror, with King Kong luster, it is a noble choice for fashion people, never fade, and has the advantage of being able to withstand mechanical impact.

They can be polished into a variety of angular patterns (such as tungsten ring, watch dial, etc.) to increase the styles and patterns of jewelry and watches. Tungsten steel was originally a kind of color-Silver Black. Now it can be electroplated into gold and black, adding aesthetics to noble famous watches.

The manufacturing process of steel ornaments mainly includes:

(1) wire cutting: use Molybdenum wire of different sizes (a kind of metal with high hardness), use a wire cutting machine, cut out the appearance of the ornament at a very slow speed, and then polish the whole hand. The more complex and difficult the styles, the slower the shipment.

(2) accurate die casting: First use wax to carve out the sample, then put it into the special gypsum, remove wax, dissolve the raw material with a high temperature of 1500~2000 degrees, and then pour it into the gypsum mold. Recompression. Demoulding, then, all-human hand polishing. Because die casting requires a special gypsum mold, the price varies.

(3) polishing surface: apply polishing wax on the high-speed rotating cotton polishing wheel, and then touch the ornament cloth wheel to make the surface bright and reflect light. Some customers misunderstood that it was electroplated. In fact, it was not electroplated, because the material inside and outside steel ornaments was the same, and only polishing was needed to have the mirror effect. For products with electroplating, we have instructions.

(4) sand drawing surface: use sandpaper tape to make the surface of the ornament into frosted effect (light does not reflect), so that there is a matte effect on the surface.

(5) sand blasting: the main working principle of sand blasting is: Place sand (very fine abrasive, silver gray) in water, use grinding liquid pump and compressed air, spray the grinding liquid to the surface of the steel jewelry at high speed through the spray gun to form a layer of silver gray coating. It makes jewelry more upscale and discoloration resistant, which is more and more popular among people of all tastes.

(6) vacuum electroplating: vacuum electroplating mainly includes ion electroplating, vacuum evaporation, sputtering plating and ion electroplating. (also called Nano electroplating electrograph method) they are all used under vacuum conditions, various metal and non-metal films are deposited on the surface of the object by distillation or sputtering. In this way, a very thin surface coating can be obtained. At the same time, it has the outstanding advantages of fast manufacturing speed and difficulty in fading, however, the price is also relatively high, and there are few types of metals that can be operated, which are generally used as functional coatings for higher-grade jewelry and watches.

(7) Resin Inlay: (also known as epoxy, hard plastic) first heat ornament with high temperature, and then apply the resin to the jewelry, because it is heat treatment, therefore, it is not easy to fall off during wearing.

(8) inlaid zircon: There are mainly two types, one is sticking with AB glue, because it is a special glue, so it is very firm. The other is that the machine press inlay is used, the workmanship is complicated, very firm, and the workmanship is fine, but the price is more expensive than that of AB adhesive.

(9) carbon fiber inlay: it is expensive, but it is used in jewelry, moving with the sight, the effect is three-dimensional, very beautiful. Carbon fiber is a kind of fibrous carbon material. It uses some organic fibers containing carbon, such as nylon silk, acrylic fiber, rayon and so on as raw materials to combine these organic fibers with plastic resin bonding, placed in an inert atmosphere and heated carbonized under a certain pressure. Carbon fiber is a new material with conductivity, high strength, low density, corrosion resistance and high temperature resistance. Composite materials made of carbon fiber and plastic can replace aluminum alloy to make light aircraft with high thrust, low noise and low power consumption. It is used on jewelry to make the surface have three-dimensional fibrous shape, and light reflection will move up and down with your sight. Make the style more special and fully show the trend.
