Copper: the market has 2 kinds of properties of the properties of copper: H59 copper, recycling and reprocessing of zinc copper alloy. The difference is that the price of raw materials, ranging from 2-3 million, will determine the final sale price in the terminal market. Faucet in China also generally exists such a phenomenon, and H59 copper is often said that the electrolysis of environmentally friendly copper, no harm to people.
With zinc as the main, containing iron, copper and other metal elements of the alloy.

aluminium alloy
Market more space aluminum as a gimmick, in fact, there is no space aluminum bathroom hardware hanging. The so-called space aluminum, with metal magnesium as the main raw material, aluminum alloy material for secondary synthesis, referred to as magnesium alloy. Magnesium is very active because of its structure, easy to explode in the process of processing, so the general use of the processing workshop for explosion proof workshop. Enterprises in the domestic mainly in the production of magnesium alloy for a national audit qualifications, products used in many high-tech aerospace, and market sales of just general to aluminum mainly alloy product of raw materials, the prices of raw materials is one third of the copper (H59 environment-friendly copper) and the national unit has not yet issued the environmental protection technical specifications of the aluminum alloy.

stainless steel
In general there are several specifications of the model itself is not the same significance.
National standard is generally in Type 304 stainless steel as the main materials, the market also has with 202, 201, 403 grades level types of raw materials to replace 304, can be imagined, this product will have a qualitative change, and ultimately harm the consumer interests.

No similar raw materials, plastics, wood and other materials produced acrylic bathroom pendant has the existence of its own advantages and disadvantages.

In the China market, the industry standard is different from the European and American countries, which includes a series of factors, such as weather, climate, water quality, natural environment and so on. As a hardware, the national industry standard of the people's Republic of China is in after the finished product surface plating need to 12 microns to anti-corrosion, rust prevention and environmental protection fundamental) and also Bureau of quality and technical supervision will be on the products of professional anti acid, anti-corrosion test. This test basic named "salt fog test" the most professional international standard machine for its products qualified testing.

Salt spray test
Need to be able to reach 96 hours of products not to be corroded side for qualified.

Aluminum alloy does not have the basic conditions to meet the test, and testing standards are not the same.
Bathroom accessories process is necessary and you simply describe: raw material - cutting - Stamping lathe milling - Pipe - welding quality inspection - polishing and electroplating assembly, packing and delivery.
