The difference between stainless steel, aluminum alloy and copper alloy in shower room

- Oct 15, 2017-

There are three basic types of hardware: copper alloys, aluminum alloys and stainless steel.


Most of the copper in the shower room comes in the form of a hinge, which is known as flat opening. Copper alloy has good corrosion resistance, wear resistance, high hardness, not easy to scratch.

Copper is divided into copper casting and forging copper. The casting is to melt the metal and then flow into a specific cavity with a particular shape, which then forms a particular shape. The forging is to heat the metal, but it is still solid, and then it is placed on the platform or in a particular shape of the mold, using a tool such as air hammer to form a specific shape. Copper casting process is simple, can be single or mass production, the price is relatively low; But because of the reason of making the principle, it is inevitable that there will be fine pores, and the density is far from forging copper. Forging can refine the metal grain, the intensity is higher than the casting, but the manufacturing cost of the mold is very high, the price will be several times than the casting copper. In addition, copper alloys must be coated to enhance corrosion resistance, and the bonding degree of coating and copper alloy is an important measure of good or bad.

The cost of forging copper itself is high and the process requirements are high, so it is used in expensive and expensive shower rooms.

Aluminum alloy in the shower room refers to titanium magnesium alloy, titanium magnesium alloy can be said as the enhanced version of aluminum magnesium alloy. The corrosion resistance and mechanical properties of titanium magnesium alloys are better than that of aluminum magnesium alloys, but they are more difficult to process, especially the heat processing. The strength of titanium magnesium alloy is three to four times that of ordinary aluminum alloy, and the higher the strength, the more pressure it can bear. So comprehensive security, economy, beautiful sex consideration, now many professional shower room manufacturer's sliding door is mainly titanium magnesium alloy.

The purity of aluminum alloy is a very important indicator, some shower room manufacturer in order to save cost, used mostly in the form of recycling waste aluminum, trachoma, pinhole, line, surface darker color, texture soft, easy to deformation or fracture. Shower room long-term contact shampoo, bath liquid and other cleanser all have more or less acid alkalinity, time a long section material is difficult to clean, easy to rusting, easily cause shower room self-explosion. Good shower room manufacturers, like Fred shower room on strictly select material, use native aluminium, primary aluminum is evener, surface can also processing through many layers, can oxidation coloring a variety of color, coating and firm, tonal and bright, corrosion resistant.

Most of stainless steel in the shower room is 304 stainless steel, 304 stainless steel is according to the United States ASTM standard to produce a brand of stainless steel, its corrosion resistance is very good, in order to keep corrosion resistance, 304 stainless steel must contain more than 18% of chromium and nickel more than 8%. There are a number of manufacturers of so-called stainless steel shower room, its actual cr-ni content is not standard, is the production of 304 stainless steel waste mixed with other materials synthesis, not only corrosion resistance is not high, and also no guarantee security. In view of the production cost of 304 stainless steel, the typical price of stainless steel shower room with lower price falls into this category, which is very unadvised to buy. As we all know, the hardness of stainless steel is very high, according to this feature, the shower room made of stainless steel is not easy to deform, long stable.

Comprehensive comparison (only the high quality products of three materials), hardness: forging copper > stainless steel > titanium magnesium alloy; Corrosion resistance: stainless steel > forging copper > titanium magnesium alloy; Easy to formability (affects the fit of all components) : titanium magnesium alloy > forging copper > stainless steel.

So buy shower room, first in the premise that determines structure reasonable, safe, material is qualified, choose material modelling according to individual preference again, can find the shower room that suits oneself.
