What kind of copper is commonly used for casting copper
Generally speaking, copper can be divided into red copper, brass, bronze and white copper.
1.Red copper: Red copper is characterized by good conductivity and plasticity, but poor strength and hardness. Red copper contains few other components, and can generally be identified as pure copper;
2.Brass is an alloy composed of copper and zinc, which can be subdivided into simple brass and complex brass. The complex brass is also named nickel brass and silicon brass with the third component, so brass is not pure copper;
3.Bronze refers to copper-based alloys other than copper-nickel and copper-zinc alloys. The main varieties include tin bronze, aluminum bronze and special bronze (also known as high copper alloy);
4.White copper refers to copper-nickel alloy, which is a copper-based alloy with nickel as the main added element. It is silvery white and has metallic luster, so it is named white copper.
When we choose copper material, we should look at its color. Generally, copper casting handicrafts are made of red copper, red copper and brass. However, inferior copper, which contains impurities, can be broken into two sections with a hand bend, and black impurities can be seen inside, which is absolutely unacceptable.
Copper handicrafts can be divided into forged copper and cast copper in terms of technology. Cast copper is the most complex one in the process, but the artistic expression of cast copper is of great value, which is incomparable with other copper handicrafts, The casting of copper sculpture will go through the 13 processes of molding, turning over the mold, making the prototype, making the wax mold, repairing the wax mold, making the mold shell, losing the wax baking, casting, cleaning the mold shell, welding, polishing, assembling and making the effect, and a perfect artwork will be produced.
