Palladium is a good thing

Yes, there is nothing wrong with my Pinyin input method. What I want to talk about here is not the literary old man Ba u200bu200bJin who passed away recently and whose surname was Li, but the precious metal palladium used as a raw material for jewelry. Of course, if you want to talk about palladium (Palladium, Pd), you have to talk about platinum (Platinum, Pt) first.　　 For Chinese people Yes, there is nothing wrong with my Pinyin input method. What I want to talk about here is not the literary old man Ba u200bu200bJin who passed away recently and whose surname was Li, but the precious metal palladium used as a raw material for jewelry. Of course, if you want to talk about palladium (pd), you have to talk about platinum (pt) first. For Chinese people, platinum is a new thing. In our traditional concept, precious jewelry is either gold or silver. In ancient times, the term'platinum' was even used as a synonym for'silver'. Over the past ten years or so, under the indoctrination of the media and advertising, we learned that there was still a thing called'Platinum', and later we learned that the more scientific name should be'Platinum', and that pt logo was also bombarded by TV commercials. The next ear is familiar. Nowadays, if you are buying a wedding ring and you do not buy platinum, it seems to be a very lost thing. Who told Maggie Cheung to tell us'rare platinum is eternally pure'! Traditionally, whether you like gold or silver is largely a color consideration. For platinum to seize the market, apart from relying on the new generation's love for silver and white, it naturally has a unique weapon. Like the diamond salesmen debeers, the International Platinum Association also chose marriage, choosing the attribute of 'eternity' as its selling point. Diamonds never wear out and are naturally the best symbol of eternal love. What about platinum? Yes, some platinum alloys do have quite high hardness. Although they will not be scratched by other things, they will generally not be worn out. For example, pt/co 950 in pt950 (95% platinum) has a Vickers hardness of 135, and it can even reach 270 after special treatment. However, pure platinum is actually a very soft thing, but the poor 43, and 'eternity' is not even touched at all. But if you want to be 'eternalTherefore, every time I see the slogan of Platinum’s 'eternal purityIn fact, it is true that gold is used for jewelry. Although platinum is popular nowadays, it is not the best choice. Here is the palladium mentioned at the beginning of the palindrome. Of course, pure palladium is also a very soft metal, with a Vickers hardness of 44, which is so much better than platinum. However, once it is not 'cleanFor example, the Vickers hardness of pt/ru 950 in pd950 is 150, which is higher than similar platinum alloys. Of course, palladium as a jewelry metal is not only characterized by hardness, but more importantly, it is affordable. On the one hand, the density of palladium is lower than that of platinum. For the same 1 cubic centimeter, platinum weighs 21.45 grams, while palladium is 12.023 grams, which is only 56% of the former. This means that the weight of palladium for jewelry of the same size is only A little more than half of platinum. More importantly, although both are rare metals, the price of palladium began to be speculated by speculators from more than 300 US dollars per ounce in 2001 to more than 1,000 US dollars per ounce. The price collapsed, and then it was beaten back to its original shape and fell to 350. About US$/ounce; while platinum is trending healthy, currently at about US$1080/ounce. Considering the density and price together, the raw material price of palladium for jewelry of the same size is only about 20% of platinum. It is a pity that in the jewellery market, benefit is never considered an advantage. Under the teaching of advertising, we all believe that being inexpensive can highlight how deep love is? Therefore, nowadays, palladium is destined to stand aside in the wedding jewelry market just like silver and k gold. Of course, if the price of palladium madly returns to $1,000 or even higher someday, then advertisements such as 'rare palladium xxxx' will appear in our lives.
