There are more and more copper doors in the market, so what kind of copper material is suitable for copper doors? There are several types of copper. The selection of materials for villa copper doors depends on the decoration style of buildings. At present, the main types of copper are as follows:

一. 黄铜一铜锌合金

1、 Brass copper zinc alloy

颜色随含锌量的增加而由黄红色变到淡黄色。黄铜力学性能比纯铜高，被广泛用于机械制造业中制作各种结构零件。 一般情况下不生锈也不会被腐蚀，塑性较好。

The color changes from yellow red to light yellow with the increase of zinc content. Brass has higher mechanical properties than pure copper, and is widely used in mechanical manufacturing to produce various structural parts. Generally, it is not rusty and will not be corroded, and has good plasticity.

二. 青铜一铜锡合金

2、 Bronze copper tin alloy

除锌镍外，青铜耐蚀性较好。

Except for zinc and nickel, bronze has good corrosion resistance.

三. 白铜一铜镍合金

3、 Cupronickel alloy

分为结构铜镍合金和电工铜镍合金，结构铜镍合金力学性能高。

It can be divided into structural Cu Ni alloy and electrical Cu Ni alloy, which has high mechanical properties.

四. 紫铜纯铜常被称作紫铜

4、 Pure copper is often called red copper

具有良好的导电性、导热性、耐蚀性、延展性好。可塑性较强被认为做铜门的优质材料。

It has good conductivity, thermal conductivity, corrosion resistance and good ductility. It is considered to be a high-quality material for copper doors.

紫铜门高雅古典，黄铜门时尚欧式。铜门选择哪种材料制作还要考虑建筑装修风格。如果比较古典中式还是用紫铜板比较合适,铝合金包装箱;如果很欧式的话建议采用黄铜板制作。

The copper door is elegant and classical, and the brass door is fashionable and European style. What kind of material should be selected for copper doors? The architectural decoration style should be considered. If it is more classical, Chinese style or copper plate is more appropriate, aluminum alloy packaging box; if very European style, it is recommended to use brass plate.

在选购别墅铜门时，可通过一看、二问、三对比的方式判断产品真伪。一看即看色泽，紫铜是铜单质，具有玫瑰红色的金属光泽，表面形成氧化膜后呈紫色，故一般称为紫铜。光泽暗淡或者表面发黑的多为劣质材料;二问即向商家询问铜板的纯度、加工工艺，或向商家索取原料的检验报告等；三对比即可以货比三家，同类型的产品，价格过低的谨慎购买。总的来说在购买之时更好向有经验的人请教，或是向正规机构咨询，避免上当受骗!

In the purchase of villas copper doors, you can judge the authenticity of the products through a look, two questions, and three comparisons. One look at the color, copper is copper, with a rose red metallic luster, the surface of the oxide film after the formation of purple, it is generally known as red copper. The materials with dull luster or black surface are mostly inferior materials; the second question is to ask the merchant about the purity and processing technology of copper plate, or ask for the inspection report of raw materials from the merchant; the third one is to compare the products of the same type with those with low price. Generally speaking, it is better to consult experienced people or consult with regular institutions when purchasing, so as to avoid being cheated!
