The difference between stainless steel, aluminum alloy and copper alloy in the shower room
The current mainstream hardware of the shower room is basically divided into three types: copper alloy, aluminum alloy and stainless steel.
Most of the copper material is in the form of a hinge in the shower room, which is called the swing door. Copper alloys have good corrosion resistance, wear resistance, high hardness, and are not easily scratched.
Copper is divided into cast copper and forged copper. Casting melts the metal and then flows into a cavity of a specific shape, which forms a specific shape after solidification; forging is to heat the metal, but it is still solid, and then placed on a platform or a mold of a specific shape, with a hammer Tools such as forging are made into specific shapes. Cast copper production process is simple, can be produced in a single piece or in batch, the price is relatively low; but because of the production principle, there will inevitably be fine pores, and the density is far less than forged copper. Forging can refine the metal grains and the strength is higher than that of the castings, but the manufacturing cost of the mold is high, and the price is several times higher than that of the cast copper. Moreover, in order to enhance the corrosion resistance of the copper alloy, it is necessary to add a plating layer, and the degree of adhesion of the plating layer to the copper alloy is an important index for measuring the quality.
Forged copper itself is costly and technically demanding, so it is used in high-end shower rooms that are expensive.
The aluminum alloy refers to the titanium-magnesium alloy in the shower room, and the titanium-magnesium alloy can be said to be an enhanced version of the aluminum-magnesium alloy. Titanium-magnesium alloys are superior to aluminum-magnesium alloys in corrosion resistance and mechanical properties, but are more difficult to process, especially in hot working. The toughness of titanium-magnesium alloy is three to four times that of ordinary aluminum alloy, and the higher the toughness, the greater the pressure that can withstand. Therefore, considering the comprehensive safety, economy and aesthetics, many sliding door manufacturers of professional shower room manufacturers are mainly made of titanium-magnesium alloy.
The purity of aluminum alloy is a very important indicator. In order to save cost, some shower room manufacturers use mostly recycled aluminum materials. The surface has many trachoma, pinholes and lines, and the color is dark, the texture is soft, and it is easy to be deformed or broken. The shampoo, body wash and other cleansing products that have been in contact with the shower room for a long time have more or less acidity and alkalinity. After a long time, the profile is difficult to clean and rust, which may easily lead to the explosion of the shower room. Good shower room manufacturers, such as Furui shower room selection, strict control, the use of raw aluminum, the original aluminum texture is relatively uniform, the surface will also be processed by multiple layers, can be oxidized and colored in a variety of colors, the coating is firm, the color is bright, preservative.
Stainless steel is mostly referred to as 304 stainless steel in the shower room. 304 stainless steel is a grade of stainless steel produced according to American ASTM standards. Its corrosion resistance is very good. In order to maintain corrosion resistance, 304 stainless steel must contain more than 18%. Chromium, more than 8% nickel. There are many manufacturers who have introduced the stainless steel shower room. The actual chrome-nickel content is not up to standard. The production waste of 304 stainless steel is mixed with other materials. It is not only corrosion-resistant, but also has no guarantee of safety. In view of the production cost of 304 stainless steel, most of the low-priced stainless steel shower rooms belong to this category, which is highly undesirable. It is well known that the hardness of stainless steel is very high. According to this characteristic, the shower room made of stainless steel is not easily deformed and is stable for a long time.
Comprehensive comparison (only compare high quality products of three materials), hardness: forged copper > stainless steel > titanium magnesium alloy; corrosion resistance: stainless steel > forged copper > titanium magnesium alloy; easy forming degree (affects the fit with each component) ): titanium magnesium alloy > forged copper > stainless steel.
Therefore, to buy a shower room, first of all, on the premise of determining the structure is reasonable, safe, and qualified materials, and then choose the material shape according to personal preference, in order to find a shower room suitable for you.
