In academic or engineering is not “steel” word, this is the dialect. Generally speaking, the steel is a carbon tool steel and carbon alloy steel, there are many types of grades.

China’s mainland market for the awareness of steel jewelry is still in its infancy, but the momentum of development is good, is gradually becoming China’s mainstream trend. Its characteristics are never fade, no deformation, no stimulation of the skin, environmental protection, its appearance shine imitation Cartier love bracelet extraordinary, in the early nineties of last century has become Europe and the United States in the mainstream of high-end fashion jewelry processing materials.
Main steel introduction and comparison:
316L stainless steel
316L stainless steel is stainless steel, corrosion resistance is very strong, very good texture. The main component is Fe, Cr, Ni, Mo, density close to iron, generally do not affect the human skin. Swiss watches are usually made of this material case, crown and strap.
904L stainless steel
904L stainless steel is a super heat-resistant stainless steel alloy, up to 21% of the chromium alloy content, so that its corrosion resistance can be comparable with precious metal materials. Is currently only used in high-tech fields, such as the aerospace, chemical and petrochemical industries, but also used in surgical transplant surgery. In 1988, Rolex took the lead in introducing 904L stainless steel into the watchmaking field, and so far, the only company in the industry to apply this material extensively and systematically to case, crown and watch manufacturing.
904L stainless steel manufacturing process is very harsh. After the first casting, the metal will be re-dissolved into a vacuum container, after purification to remove impurities contained therein, and confirmed by the scanning electron microscopy quality, can be used to manufacture watches. Because of this extremely difficult to damage the steel material, the manufacturing and stamping process is a great challenge – it must go through special tools and process processing, including rolling steel, die stamping, and ultimately made of watch parts.
316L and 904L are an austenitic steel body, 904L contains nickel, chromium and copper, 316L does not have. 904 compared to more resistant to corrosion just wear, the price is 316 times 3 times
Titanium alloy is based on titanium to join other Replica Cartier jewelry elements of the alloy. Titanium has two kinds of homogeneous amorphous: 882 ℃ below the closed hexagonal structure of α titanium, 882 ° C above the body of the heart of the β titanium.

Titanium alloy features:
Titanium alloy density is generally 4.51g / cubic centimeter, only 60% of steel, pure titanium strength is close to the strength of ordinary steel, some high-strength titanium alloy than the strength of many alloy structural steel. So the titanium alloy specific strength (strength / density) is much larger than other metal structure materials.
Good corrosion resistance
Titanium alloy in the humid atmosphere and sea water medium work, its corrosion resistance is much better than stainless steel; pitting corrosion, acid corrosion, stress corrosion resistance is particularly strong; alkali, chloride, chlorine organic products, nitric acid, sulfuric acid And so have excellent corrosion resistance.
Rose gold (rose gold) is a gold and copper alloy, because of its very stylish, beautiful rose red color, which is widely used in jewelry design and processing. Also known as pink gold (pink gold), red gold (red gold). Because this metal was once popular in Russia in the early nineteenth century, it was also called Russian gold, but the term is now rarely used.

Rose gold watch watch has long been in the antique watches (pocket watch) can often see, considered more personalized design, romantic and elegant, more alternative, and even some people say that the rose gold looks very ” Demon “. Rose gold watch watch, including the use of pink gold watch, asked in the dial and strap with the coordination, such as: dial commonly used champagne color, with black and more, and leather strap with brown and black many.
Rose gold features
Rose gold composition: pure gold + copper + silver / zinc. Because of its high proportion of synthesis, with a strong ductility, high hardness, color and other characteristics, while the integration of 25% of other metals, hardness, easy to deformation or scratches, the use of precision fine gold design, can enjoy Play complex design ideas. According to reports, K gold plasticity is very strong, through the modern technology pull out the wire than the human hair is also fine. In addition, the appearance of gorgeous K gold jewelry process complex, the production process www.ourlovestore.com cumbersome, need to go through a professional machine drawing processing woven weaving, so the shape of exaggerated, different styles of gold jewelry than the general 18K gold expensive. As K gold jewelry prices higher, more people do not buy for “every day wear”, but with clothing to attend different occasions.
Rose gold color
Usually, rose gold from 75% of the 18K gold and other alloys (commonly known as three-color gold). Hardness than pure gold, compared with the traditional gold and platinum, pink rose gold not only can make the color of colored stones more concentrated, but also reflects the fine metal material, delicate. Such as tide Acer, Jinlin, the new Jinshan, the old temple launched the rose gold series, its pink, rose and other warm colors to bring people warm and happy; in style is also varied, heart-shaped, Pear-shaped, emerald-shaped. Variety of different styles of jewelry, can be described as bright and dazzling, women, whether it is professional wear, or evening dress and dress, with the show are elegant temperament.
