 1. Properties of copper

Copper is a reddish metal with luster, good ductility and easy to process. Copper is stable in dry air and easily oxidized in humid environment. It is soluble in nitric acid and hot concentrated sulfuric acid, and slightly soluble in hydrochloric acid and dilute sulfuric acid.It has good thermal conductivity and etching and processing performance. The application of copper in nameplate is mainly based on copper alloy, such as brass, which is copper-zinc alloy (zinc is less than 50%);Bronze, a copper-tin alloy (tin under 35%).

 2, the coloring of copper

Previous copper plate, the main means of adornment is chrome plated, for light and corrosion protection, now it is not using copper as the main purpose of the name plate, and the true natural beauty of the nature of the action should is the use of copper and copper generated compounds of of primitive simplicity is beautiful, for other material part of nameplate, and reflects its unique style and artistic value.The classical coloring of copper and its alloys is most commonly used in the following ways.

 1. Tan

Basic copper carbonate: 40~120g/L; Temperature: 15~25℃; Ammonia water: 200mL/L; Time: 5~15min. The work piece of pure copper or steel plating can be immersed in the above solution and shaken continuously. After 5min, it can turn brown and deepen continuously.Clean and dry before polishing.Polishing is the workpiece and leather edge material at the same time in the barrel of rolling mill, so that the raised part of the show the natural color of copper and concave part of the formation of a shallow deep transition tone, appear antique, elegant ancient.Apply a coat of varnish after coloring for lasting preservation.

 2. The ancient black

Cook copper or copper alloy in vinegar or smoke with straw, make lampblack film is adherent, can besmear varnish again.

 3. Bronze

The copper alloy will be boiled with vinegar first, and then with ammonium carbonate, sodium chloride, copper sulfate and other aqueous solution coating, after a few days will produce bronze rust. You may also like:nameplate of camera;Please click to view ~
