五金配件要看原料和做工

专业人士表示,常用的五金配件主要包括铜、铝合金、不锈钢和铁,它们的报价也相差很大。目前,不锈钢五金大多用于家庭装修,但不锈钢原材料存在原材料不纯、水渍印刷简单等缺陷,现在许多家庭开始使用铝合金原料的配件。
据统计,销售市场上某些店家声称的铝材料原本只是含有铝成份的铝合金材料,在其中掺合有硅、镁等其他成份,而表面膜层薄厚及表面解决技术性等因素,也一般危害着材料的价格及品质。外表面处理技术主要包括氧化、打磨、电镀、木纹和烤漆等。,而且商品报价也相差很大。
专业人士表示,市场上常见的铝合金材料主要包括铝镁合金和氧化铝。两者的价格差异接近三分之一,因为氧化铝和铝镁合金的数据在外观上相似,使得消费者很难区分它们,但它们仍然可以与手感、水渍等区分开来。铝镁合金的数据相对较重,外观相对光滑,不仅仅显示水渍,而且具有良好的耐磨性。然而,氧化铝数据外观粗糙,变黑简单或显示出水渍痕迹。另一方面,如果两个表面都有轻微的划痕,铝镁合金数据将被简单地擦除,而氧化铝将难以去除。此外,由于孔间距和型号的不同,门把手的报价也会有很大差异。

当心不锈钢变成“不锈钢”
一些市民报告称,在购买不锈钢配件时,他们发现有大量的不锈钢,即不锈钢材料中混入了大量的铁,价格相差近两倍。以浴巾架为例,不锈钢原材料的报价平均每200元,而不锈钢的报价只要每70元,外观基本相同。然而,不锈钢材料外观较亮,长期使用的不锈钢外观简单、暗、生锈。
此外,还有一些以劣质铝合金为原料的假冒商品,其外表面涂有一层金属光和假冒高级不锈钢来区分这两种数据。市民在购买时可以撞击他们的外表。如果大声的噪音被宣布,大部分是不锈钢。如果是沉闷的噪音,很可能是铝“覆盖在外套里”的金。

Selection of hardware fittings depends on raw materials and workmanship
Professionals said that the commonly used hardware accessories mainly include copper, aluminium alloy, stainless steel and iron, and their quotations vary greatly. At present, stainless steel hardware is mostly used for household decoration, but stainless steel raw materials have defects such as impurity of raw materials, simple watermark printing and so on. Now many families begin to use parts made of aluminum alloy raw materials.
According to statistics, the aluminum materials claimed by some shop owners in the sales market were originally aluminum alloy materials containing aluminum content. In addition, silicon and magnesium were added to the aluminum alloy materials, and the factors such as the thickness of the surface film layer and the technical solution of the surface were also harmful to the price and quality of the materials. External surface treatment technology mainly includes oxidation, grinding, electroplating, wood grain and baking paint. And the quotations for goods are quite different.
 
Professionals say that the common aluminium alloy materials in the market mainly include aluminium magnesium alloy and alumina. The price difference between the two is close to one-third, because the data of alumina and aluminium-magnesium alloys are similar in appearance, which makes it difficult for consumers to distinguish them, but they can still be distinguished from hand feel and water stains. The data of Al-Mg alloy is relatively heavy and its appearance is relatively smooth. It not only shows water stain, but also has good wear resistance. However, the alumina data are rough in appearance, simple in blackening or showing water stains. On the other hand, if there are slight scratches on both surfaces, the Al-Mg alloy data will be simply erased, while the Al-Al alloy data will be difficult to remove. In addition, due to the difference of hole spacing and model, the price of door handle will also vary greatly.
 
Beware of stainless steel turning into "stainless steel"
 
Some citizens reported that when they purchased stainless steel parts, they found a large amount of stainless steel, i.e. stainless steel materials mixed with a large amount of iron, the price difference was nearly double. Take bath towel rack as an example, the average price of stainless steel raw materials is 200 yuan, while the price of stainless steel is only 70 yuan, the appearance is basically the same. However, the appearance of stainless steel materials is bright, and the appearance of stainless steel used for a long time is simple, dark and rusty.
 
In addition, there are some counterfeit commodities made of inferior aluminium alloys, whose outer surface is coated with metal light and counterfeit high-grade stainless steel to distinguish the two kinds of data. Citizens can bump into their appearance when they buy. If loud noise is announced, most of it is stainless steel. If it's a dull noise, it's probably the gold that aluminium "covers in the jacket".
