Now the shower room material in the market in addition to everyone's common aluminum alloy as the main material, there are some higher grades of stainless steel for the main material, appearance looks more upscale atmosphere, of course, the price is higher than the aluminum alloy shower room. Some owners in the shower room, some tangled, the performance of the stainless steel shower room is not very understanding, do not know the stainless steel shower room and aluminum alloy shower room which kind of good?
Here is a comparison of the advantages and disadvantages of the aluminum alloy shower room and stainless steel shower room.
1. Comparison of corrosion resistance
(1) rust: aluminum alloy is not rusty. The main alloy elements contain copper, silicon, magnesium, zinc and manganese. The secondary alloy elements are nickel and iron, and the iron content of the aluminum alloy is very small. Instead of stainless steel, it mainly relies on the chromium oxide film formed on the surface (protective film) to resist corrosion. If the film is subjected to continuous special destruction, the metal surface will be corroded. Of course, the protective film is thin, solid, fine and stable.
(2) the cleaning supplies for bathing are more or less alkaline, for a long time, with deposition or cleaning, the material will be corroded, but the problem will not exist for the stainless steel, but the surface of the aluminum alloy will have a corrosion reaction.
(3) if the environmental salt is high, like living seaside, stainless steel in the presence of chloride in the environment, corrosion is very fast, it is recommended to choose 316 stainless steel, its corrosion resistance, atmospheric corrosion resistance and high temperature strength is especially good, processing hardened, can be used under harsh conditions, the price will be higher.
Two. Comparison of hardness
The hardness of stainless steel is larger than that of aluminum alloy, so many shower rods and shower columns in many shower rooms are made of stainless steel and more sturdy. The choice of stainless steel material for shower room is 304 stainless steel, high temperature resistance, excellent corrosion resistance and good intergranular corrosion resistance.
Three. Comparison of appearance effect
Stainless steel is polished by high brightness, and the worst surface quality is above 8K. It is very beautiful and texture. The surface of aluminum alloy and profile is processed by oxidation coating, and the appearance quality of stainless steel will not be processed any more.
Four. Comparison of cleanness and convenience
Scribble on the surface of stainless steel can be easily cleaned; the surface of aluminum alloy is easy to leave traces, and it is difficult to remove. And in the wet environment such as bathroom, aluminum alloy will oxidize and hang "white ash" phenomenon, which will bring difficulty to cleaning.
Reminding you: cleaning the stainless steel surface should be cleaned with stainless steel lines, some of the surface processes are unidirectional (for example, we now say more wire drawing is one way). This is not only because it is easy to clean, but also does not breed bacteria easily.
Five. Price comparison
The stainless steel shower room is more expensive than the aluminium alloy shower room. Shower room is not big, although the one-time investment is higher, but in terms of safety and service life, it seems that the aluminum alloy is better.
In a word, the aluminum alloy is strong and durable, the oxidation resistance is not rusty, the drawing process is mature and simple, the appearance is simple and beautiful. Of course, the most important thing is the real price, so it is still the mainstream of the shower room. Stainless steel is expensive because of its high cost and complex technology, so it is generally used in a high grade product.
It is important to note that many small brands in the market cater to the psychology of consumers in favor of stainless steel and use low-grade low grade stainless steel as the main material (such as 301, 302) to fake 304 stainless steel to deceive consumers. These low standard stainless steel are easily rusty and corroded in the use of the bathroom, and their use is not even more effective than the common aluminum alloy. Kim.
