At present, many daily necessities are made of materials such as copper, iron, stainless steel, etc. These materials contain heavy metal elements, which may cause excessive standards if not handled properly.
For example, the main element of stainless steel contains manganese, chromium, and nickel. To maintain corrosion resistance, stainless steel must contain a certain amount of chromium. If the chromium is not handled properly, it may lead to excessive chromium. Similarly, improper handling of manganese may result in excessive manganese.
The copper alloy used to make the faucet contains trace amounts of metal elements such as iron, aluminum, and lead. If there is no lead, it is difficult to form during casting. The higher the lead content, the easier the casting process is. Therefore, the copper faucet on the market generally contains a certain amount of lead. If the lead-free process is not done well when the factory is manufactured, it will lead to excessive lead.
Another reason is that the company’s technology and equipment are aging, resulting in the control of trace elements. Usually, when the new equipment is first put into production, its products are qualified, but when the equipment is used for a long time, the trace elements of the product will exceed the standard. This situation cannot be repaired from a technical point of view, and only new equipment can be replaced. However, some factories continue to use it in order to save money. This is a technical problem and a cost issue.
A bathroom equipment seller told reporters that most of the faucets on the market today are copper cores, but the quality is not good. Small manufacturers, cheap faucets, the possibility of lead exceeding the standard is very large. This is because some manufacturers do not buy standard brass alloys in order to control costs, but purchase cheap lead brass from small workshops as raw materials. This lead brass is often high in lead but at half the price of brass alloy.
How to distinguish inferior faucets from the price? Some insiders told reporters that a copper faucet with a formal process should cost more than 100 yuan, while tens of faucets are likely to use lead brass.
“Compared to large products, tens of dollars of faucets are really not worth spending so much time and energy to pick one by one, and will not pay attention to the problem of excessive lead content.” A Shanghai resident who is renovating at home told reporters.
In this regard, some insiders said that domestic consumers pay insufficient attention to the quality and safety of faucets, which also makes many unqualified inferior faucets have opportunities.
