1. Copper material top
The copper gyro handle is heavy, the common processing method is casting, CNC cutting face straight out, polishing anti-oxidation treatment, stone washing and grinding, making old black processing. In terms of production cost, the cost of polishing and anti-oxidation treatment, stone cleaning and frosting treatment is higher, and the cost of making old black processing is lowest. The two pieces of vintage aunts in the main building are actually the products that players make their own.
Below is the surface that the stone washes the ground of the ground to wash the ground ~ ~ ~, the red copper gyro that does not suggest to buy mirror polishing, easy to scratch mark.
2. Titanium alloy top
Titanium alloy surface can do mirror polishing, laser engraving, bluing, grinding and other processing, so the titanium alloy fingertips gyro can be more beautiful, frosted is not much said.
Mirror surface technology is the biggest advantage of the titanium alloy gyroscope, titanium alloy is better than stainless steel and copper mass high hardness, wear resistance, so the mirror processing of gyro is suitable for playing with for a long time, not easily get scratches.
3. Stainless steel top
Stainless steel gyro (also have zinc alloy) common technology is blue, and add the special coating for stainless steel gyro are generally not copy foreign titanium alloy design of gyro, people don’t like this kind of products .
The color gyro in stainless steel gyro is attractive, but it is the abrasion resistance, if you start to pay attention to protect the oxidation layer.
4. Aluminum alloy top
Aluminum alloy gyroscope is easy to distinguish, the main is lighter in weight, this kind of products are mainly used mobile phone aluminium magnesium alloy shell of borax, such as oxidation process, can make the color of the beautiful ~ ~ ~. The disadvantage is that the weight is lighter and the inertia is small, so the rotation is usually below 4 minutes.
