Hardware gadgets material and workmanship can not be ignored 
 It is understood that the general hardware accessories, the four components of copper, alloy, stainless steel and iron, its price is also a big difference. Currently the largest home improvement use stainless steel hardware, stainless steel, a material impure, easy to print out the water stains and other shortcomings, many families began to use aluminum alloy parts. According to industry sources, some businesses claim that the aluminum is only containing the aluminum composition of the alloy, aluminum alloy material which blends with other ingredients, including silicon, magnesium, aluminum material surface layer thickness and surface treatment have a great relationship, these factors tend to affect the price and quality of the material. A corporate CEOs introduced the surface treatment process such as oxidation, grinding, plating, wood grain and paint, prices vary greatly, the framework of the sliding door, for example, the use of oxidation products of the grinding process the market average in each square meters, about 180 yuan, the product of the plating process has reached around 260 yuan per square meter, the price difference of nearly 45%. 
 Common aluminum alloy on the market are mainly two kinds of aluminum-magnesium alloy and alumina, the price difference between nearly one-third of consumers in identifying the surface of the alumina and aluminum-magnesium alloy material looks almost more difficult than , but consumers can judge from the feel, water stains. The experts said that the relatively heavy aluminum-magnesium alloy material, the surface is smooth, not prone to water stains traces, good toughness; alumina surface rough, easy, black and appear water-soaked traces. If both the surface of minor scratches on the aluminum-magnesium alloy material is easy to erase, while alumina is difficult to remove. In addition, the door handle but also because the pitch, different models, prices also vary widely.
