Copper
: There are two types of copper in the retail market: H59 copper and recycled zinc-copper alloy. The difference is that the price of raw materials varies from 20,000 to 30,000, which will also determine the final sale price in the terminal market. This phenomenon is also common in faucets in China, and H59 copper is commonly referred to as electrolytic environmentally friendly copper, which is harmless to people.
Zinc alloy
An alloy containing mainly zinc molecules and covering metal molecules such as iron and copper.
Aluminum alloy
Most of the market uses space aluminum as a gimmick. In fact, there is no bathroom hardware pendant with space aluminum. The so-called space aluminum is an alloy composed of metallic magnesium as the main raw material and aluminum as the secondary raw material, referred to as magnesium-aluminum alloy for short. Because of its very active structure, magnesium molecules are prone to explode during processing, so most of the processing workshops generally used are explosion-proof workshops. Most of the domestic companies that mainly produce magnesium-aluminum alloys have first-level qualifications approved by the state. The products are mostly used in high-tech aerospace. What the market sells is only general aluminum alloy products whose raw material prices are copper. (Less than one-third of H59 environmentally friendly copper) The relevant national units have not yet issued environmental technical indicators for aluminum alloys.
Stainless steel
Generally, there are models with several specifications, and their meanings are also different.
The national general standards generally use 304 stainless steel as the main material. Some people in the market use 202, 201, 403 and other secondary grade materials to replace 304. It is conceivable that the product will undergo qualitative changes and ultimately damage The interests of consumers.
In addition, bathroom accessories made of materials such as plastic, wood materials, and acrylic have their own advantages and disadvantages.
In the Chinese market of bathroom hardware accessories, the industry standards are different from those of countries such as Europe or America. This includes a series of factors such as the country's weather, climate, water quality, and natural environment. As for hardware, the national industry standard of the People's Republic of China is: the surface plating of the finished product needs to reach 12 microns (to play the basis of anti-corrosion, anti-rust and environmental protection). In addition, the Technical Quality Supervision Bureau will conduct professional anti-acid and anti-corrosion tests on the products. , This kind of test is basically named "salt spray test". The most professional international standard machine conducts qualification test on its products.
