Iridium doped barra de oro de tungstenos high inspection costs

Buy physical gold bullion to be the people is an important way for investment purposes, but ICBC sold bullion investment-oriented customers but was questioned adulteration. Although ICBC denied the challenge, but industry insiders believe that the incident also reflects the investment in gold bullion there can not be ignored in the inspection problem.

Tianjin Gold Jewelry Association Secretary-General Gui Quan told reporters, many banks are concerned about the precious metals business and investment-oriented bars placed in a prominent position on the operating room. But the reporter also found that, in addition to Industrial and Commercial Bank of China, China Construction Bank and a few other banks launched the "ICBC gold", "golden CCB" create their own brand products, most banks only physical gold sales channels. That is, in the majority of banks to buy physical gold, if there is still gold producer after-sale issues bear responsibility. And to the bank's customers to buy gold, fancy is precisely the flagship bank.

"This incident is to dampen the impact or greater public confidence in buying physical gold," the person in charge of Tianjin Song told reporters that his concerns. He said that in physical gold sales, although the proportion is growing banking channels, but the amount of gold store sales can maintain double-digit annual growth of about. But now, a lot of physical gold investors, said: "The results of the investigation and so to say."

Tianjin jewelry Campbell Supervision and Inspection Center Director Caowei Yu told reporters: "If the Internet said is mixed with the gold iridium or tungsten, testing it really difficult." Because of the incorporation of gold or tungsten iridium, not two substances are uniformly mixed, and is similar to the surface mixed with sand. Currently, the test bars are mainly two ways: one is non-destructive testing, through the X-ray spectral test for gold bullion, the price of 200 yuan, but this method is ineffective against incorporation of iridium or tungsten; Another method is chemical testing , first cutting off part of bullion dissolved in aqua regia, through the analysis of the chemical composition to determine the purity of gold, but this test method once to 1,000 yuan, not only high prices, but also loss of part of the gold.

Due to the test level and cost constraints, and now all banks and gold companies, only repurchase its own brand or type of investment bullion sales channels, which also in turn will increase the cost of public investment in gold. In this regard, Li Gui fully recommend that investors buy gold or through formal channels, while not freeloaders, in order to maximize protection of their interests.
