Molybdenum is a metal that is easy to blacken. There may be some black spots on the surface. At this time, using a strong toothpaste to remove the black spots almost perfectly! Remember that if black spots are not a quality issue, but the chemical nature of molybdenum, molybdenum will become completely black in the air, but there are effective ways to deal with this problem.

【note】
1Select theoretical density 10mm positive tolerance dense molybdenum plate cutting and polishing, high-precision laser engraving, the grinding process basically completely removes the cutting marks, no need to worry about cutting hands, pure molybdenum nature is not easy to process hard
2 purity 9905 molybdenum, theoretical density, average 10.3g, of course, impossible 100% perfect, has done its best to perfection, laser lettering clear contrast is very high, very delicate, please specify in advance if there are special requirements.
3 When leaving the factory, the edges and corners are distinct, the cling film is carefully wrapped, and you should pay attention to the bumps.
4 special attention of molybdenum, molybdenum metal, chemical stability, corrosion resistance is relatively strong, the general corrosive substances exposed in the lives of ordinary people can not dissolve it, but molybdenum will slowly turn yellow and brown in humid air until Turning black, that is to say, molybdenum is afraid of moist air, it will slowly darken, but after all, molybdenum is also a corrosion-resistant metal, this black film only stays on the surface, it will not get worse and worse, you need to use toothpaste On its surface, then rubbing it twice, it seems that the molybdenum, which looks very corrosive, will instantly shine as new.
