Designers！Hello everyone！

We talked about last time

According to the different oxidation stages of copper

It is generally called according to its color

red copper，brown copper，green copper

This is actually a simple visual call

But as we go deeper into

Today we will lead you from the perspective of professional terms

different components of copper——copper alloy

(brass 5 16 tube)Recognize different types of copper

Except for pure copper

Most of the copper exists in the form of alloys

Copper alloy according to different alloy composition

(brass 5 16 tube)divided into：brass、bronze、gold bronze and cupronickel

01

brass

(Brass sample↑)

Brass is an alloy of copper and zinc，made of copper、Brass composed of zinc is called ordinary brass，If it is a variety of alloys composed of two or more elements, it is called special brass。Brass has strong wear resistance，Brass is often used to make valves、water pipe、Air conditioner connecting pipes and radiators, etc.。

in copper alloy

The most versatile brass is an alloy of copper and zinc

Named for the color yellow

Has good mechanical properties and wear resistance

Brass is a beautiful natural material

Its surface color gradually changes over time

Using brass as the surface cladding material of the building

can form naturally、Facades with varying shades

leave a warm impression

(brass 5 16 tube)Properties of Brass

beautiful color、durable、Environmental friendly

Make your designs look their best

Give people a bright surprise

Ado，previous case！

country city：Finland.Lahti

(brass 5 16 tube)

The project is located in the downtown area of Lahti

A transportation hub for railway transit and long-distance passenger transport

The famous red brick building railway station

sets a strong tone for the hub

Designer's choice of brass

the building has a visual impact on the city

Building wrapped in alloy copper

Also shining under the light of the city lights

02

(Bronze sample↑)

Bronze is the earliest alloy in the history of metal smelting，in pure copper（copper）alloys with added tin or lead，of special importance and historical significance，with pure copper（copper）compared to，Bronze has high strength and low melting point（25%tin smelted bronze，melting point will drop to800℃。pure copper（copper）The melting point of1083℃）。good bronze casting，Wear-resistant and chemically stable。

(bronze surface texture↑)

Named for the color blue。

Bronze is one of the earliest alloys in history

Other elements such as aluminum、beryllium、manganese、silicon alloy copper

Bronze generally has good corrosion resistance

Abrasion resistance、Castability and excellent mechanical properties

Wuhan Qintai Grand Theater ▼

architect：Guangzhou Pearl River Foreign Capital Architectural Design Institute

Wuhan Qintai Grand Theater uses bronze curtain wall

Shows the regional cultural heritage and development of the place

It shows the bronze culture of Chu and Han

The copper plate adopts multiple etching imitation cast copper curtain wall panels

Bronze culture is reproduced in modern society

03

gold bronze

(brass 5 16 tube)(Copper sample↑)

Gold and copper composition alloy and gold alloy composed of other components of gold-copper alloy。There are：Gold copper alloy、Gold copper nickel alloy and gold copper palladium alloy。Gold copper alloy has a wide purpose。Fujin gold copper alloy in English、Beauty and Canada and other countries have been used to make gold coins。Gold copper alloy has good corrosion resistance and low vapor pressure，Melting point，Is excellent solder alloy，It does not cause cracking of tapered alloy，Suitable for brazing electric vacuum devices。

Gold copper is gold and copper alloy

A new copper gold alloy material applied to curtain wall

Gradually form a significant warm gold surface

Although it is no longer flashing
