The difference between copper alloy, aluminum
The mainstream hardware materials of shower rooms are basically divided into three types: copper alloy, aluminum alloy and stainless steel.
Most of the copper materials in the shower room are in the form of hinges, which is the so-called flat door. Copper alloy has good corrosion resistance, wear resistance, high hardness, and is not easy to scratch.
Copper is divided into cast copper and forged copper. Casting is to melt metal and then flow into a cavity with a specific shape. After solidification, a specific shape is formed. Forging is to heat the metal, but it is still solid, and then placed on a platform or hole. , The compactness is far less than forged copper. Forging can refine the metal grains and has higher strength than castings, but the manufacturing cost of the mold is very high, and the price will be several times higher than that of cast copper. Moreover, copper alloys must be plated in order to enhance corrosion resistance, and
The degree of adhesion between the plating layer and the copper alloy is an important indicator of good or bad.
Forged copper itself has high cost and high process requirements, so it is used in expensive high-end shower rooms
Aluminum alloy refers to titanium-magnesium alloy in the shower room. Titanium-magnesium alloy can be said to be an enhanced version of aluminum-magnesium alloy. The corrosion resistance and mechanical properties of titanium-magnesium alloy are better than aluminum-magnesium alloys, but they are more difficult to process, especially hot processing. Very difficult.
The strength and toughness of titanium-magnesium alloy is three to four times that of ordinary aluminum alloy. The higher the strength and toughness, the greater the pressure it can withstand. Therefore, considering safety, economy and aesthetics, the sliding doors of many professional shower room manufacturers are mostly made of titanium-magnesium alloy.
The purity of aluminum alloy is a very important indicator. In order to save money, some shower room manufacturers use recycled aluminum materials, which contain trachoma, pinholes, lines, dark color, soft texture, and easy to deform or break. Shampoos, body washes and other cleansing products that have been in contact with the shower room for a long time have more or less acidity and alkalinity. The profiles are difficult to clean and rust over time, which can easily cause the shower room to explode. Good shower room manufacturers, like Furui shower room selection
Strictly check, the primary aluminum is used, the texture of the primary aluminum is relatively uniform, and the surface will be treated with multiple layers, which can be oxidized and colored in a variety of colors, the coating is firm, the color is bright, and it is corrosion resistant.
Most of the stainless steel in the shower room refers to 304 stainless steel. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. 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 so-called stainless steel shower rooms launched by many manufacturers. The actual content of chromium and nickel is not up to the standard. It is synthesized by mixing 304 stainless steel production waste with other materials. Not only is the corrosion resistance not high, but the safety is not guaranteed. In view of the production cost of 304 stainless steel, most of the low-priced stainless steel shower rooms fall into this category, and it is not recommended 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 and is stable for a long time.
