What materials can we machining for watch?
There are many parts required to make up a watch, and what you can see at a glance is the case. In addition to directly caring for the "internal organs" of the watch, such as the movement, dial, hands, etc., the case also determines the quality of the watch to a large extent. Various properties, such as: water resistance, dust resistance, anti-magnetic properties, shock resistance... The materials used to make the watch case have their own characteristics:
Stainless steel watch case
1: As the preferred material for many watch brands, it has good texture, strong corrosion resistance, anti-rust, anti-magnetic, high strength and toughness.
2: Never fade, not deform, no irritation to the skin, less prone to allergies, comfortable to wear.
3: It can be polished, frosted, and can be coated with various materials. 316L stainless steel has high hardness and brightness. No oxidation, high density. The polished case has a fairly white luster, so it is loved by fashionistas.
Ceramic watch case
Advantages of Ceramic Watch Cases
1. Ceramics are known for their hardness, especially when compared to steel or other metals. This material is typically three to four times harder than stainless steel. There are no signs of wear even after years of use.
2. Although ceramic watches look heavy, they are lighter than most metals and have a light texture, which is basically similar to aluminum. It is easy to wear on the wrist and comfortable to wear.
3. Because ceramic watches do not contain metal, they will not rust and are more resistant to corrosion. Most people, even those with sensitive skin, can wear a ceramic watch without experiencing skin irritation or allergic reactions. Some brands use ceramic in sports and diving watches because it can also withstand the erosion of seawater.
4. Ceramic is an excellent material for black watches. Unlike coated metal watches, ceramic watches are more resistant to fading and abrasion. In addition, the ceramic is not affected by UV rays, which means that the watchchr(34)s color will not fade even when exposed to sunlight.
Many watch manufacturers use ceramics such as - Rolex, Omega, Rado, IWC, etc.
Disadvantages of Ceramic Watch Cases
1. Although ceramic is scratch-resistant and durable, it is prone to chipping;
2. The processing is difficult, and the process of manufacturing ceramics is very complicated. Heating and cooling require a lot of time, the process control is complicated, and the yield is relatively low. Once formed, the ceramic needs to be polished, which also adds to the cost, which is one reason why ceramic watches tend to be more expensive than metal watches.
3. High price, as just mentioned, because ceramics are difficult to manufacture, watches made of this material are more expensive compared to traditional metal watches.
Tungsten steel watch case
This material is different from the materials used in general watches. Its hardness is close to that of natural diamonds, it is not easy to wear, its brightness is like a mirror surface, it will never fade, and it can withstand mechanical shocks. Tungsten steel was originally a color - silver, and now it can be electroplated into gold and black, adding aesthetics to noble watches. The disadvantage is that it is easy to break without falling, so be careful when using it.
Titanium watch case
Titanium has very good advantages as a watch material, such as: titanium watches are quite comfortable to wear because they are surprisingly light; titanium is hypoallergenic, it does not contain nickel, and it is very comfortable to wear even when the skin is sweaty ;Since titanium is harder than steel, titanium watches are more durable; corrosion-resistant properties make titanium especially suitable for diving watches; titanium is very environmentally friendly, it comes from the earth and is recyclable.
high strength
The density of titanium alloy is generally about 4.51g/cm3, which is only 60% of steel. The strength of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloys is much greater than that of other metal structural materials.
good corrosion resistance
Titanium alloy works in humid atmosphere and seawater medium, and its corrosion resistance is much better than stainless steel; its resistance to pitting corrosion, acid corrosion, and stress corrosion is particularly strong; it is resistant to alkali, chloride, chlorine, organic substances, nitric acid, sulfuric acid etc. have excellent corrosion resistance.
