Other metal material of the strap.

1) copper is the best thing in the wristwatch, it is cheap, and the characteristic is easy to process, it is mainly used in the machine core, and most of the current use is the brass alloy splint. Usually we see the color of the machine is yellow and white, the yellow machine is usually coated with titanium oxide, the white machine core is galvanized nickel alloy.
2) steel, chromium and nickel compound of pure steel, chromium and nickel compound stainless steel processing is difficult, corrosion resistance and abrasion resistance are better than the former, the surface can also don't electroplating, plating only do polishing or sand blasting, sand processing, forming the appearance of the effect of different stereoscopic effect.
3) titanium is emerging as a result of the boom of the all-steel watch. Its material is called the "aerospace age" metal. What is titanium? Titanium is found in the earth's crust, which can be bright and shiny metal, or silver gray, dark gray powder. Titanium is a lightweight, hard, heat-resistant, cold-resistant metal with an oxide film on the surface to prevent wear and corrosion.
4) tungsten titanium alloy with 1000 mpa pressure will first tungsten carbide and titanium carbide powder pressing into embryos pieces, die casting, and then again at 1450 degrees Celsius in the special furnace high temperature sintering for high density parts, finally through multiple processes after grinding with diamond powder is made from tungsten titanium alloy sparkle, wear-resisting performance is good.
5) tungsten steel is of high hardness, wear resistance, clear appearance, bright and bright, and is called "wear resistant material". It can be used in combination with steel, and it can be used to make the outer surface of the shell or the strap, the grain, and the surface of the shell and the surface to be abrasion resistant and decorative. (there is a drawback to tungsten steel, which is too heavy.)
6) precision ceramic precision ceramic is bright and clean, wear-resisting, not hurt the skin, the main ingredient is zirconia, under the condition of a certain temperature to obtain a good processability, again through the use of advanced processing methods, made into fine watchcase, strap, all sorts of color can also be through a particular way, more show luxuriant nobility.
7) high-tech ceramics will be highly refined zirconia or titanium carbide powder, and the powder will be formed in a sintering furnace at a temperature of 1450 degrees Celsius. Diamond powder is used to make a unique gloss of high-tech ceramics.
8) the high tech lanthanum will break down the rare earth elements lanthanum and refine them into fine particles, which can be put into a furnace and compressed by high temperature and pressure. Its hardness is higher than tungsten titanium, high-tech ceramics, more difficult to wear out, and emit mysterious light.
9) blue steel blue steel is a kind of steel which is formed by special cooking process, so it will emit a brilliant blue color. Blue steel is mainly used for Pointers. In addition to aesthetics, there is more corrosion resistance.
