Copper
In watches, copper is the best thing. It is cheap, and the characteristic is extremely easy to process. It is mainly used in movement, and most movement uses brass alloy plywood. Usually the colors of the movement we see are yellow and white. The yellow movement is usually plated with titanium oxide. The white movement is galvanized nickel alloy.
Compound of steel, chromium and nickel
Stainless steel is difficult to process, and its corrosion resistance and wear resistance are better than the former. The surface can be electroplated or not, and only polished, sandblasted, and sand drawn. Form a three-dimensional appearance with different effects.
titanium
Due to the craze for all-steel watches, titanium gradually emerged. Its material is called “Aviation Age” metal. What is titanium? Titanium metal is found in the earth’s crust, and its appearance can be a bright and shiny metal. Or silver gray, dark gray powder. Titanium is a light, hard, heat-resistant and cold-resistant metal. There is an oxide film on the surface to prevent wear and corrosion.
Tungsten Titanium Alloy
First, press the tungsten carbide and titanium carbide powder into the blank with a pressure of 1000 Pa. Then die-cast the mold, and then sinter it into extremely high-density parts at a high temperature of 1450 degrees Celsius in a special furnace. Finally, after multiple processes and polished with diamond powder, a sparkling tungsten-titanium alloy is made with good wear resistance.
