What is copper?
Red copper (also known as pure copper) is mainly composed of copper (Cu) from 99% or more . This is a metal with a characteristic red-orange color, easy to recognize. Red copper has extremely high electrical and thermal conductivity, widely used in the fields of: electricity - electronics, precision mechanical processing, production of high-tech components...
Outstanding features of copper:
- Color: Metallic orange red.
- Density: About 8.96 g/cm³.
- Conducts electricity and heat very well.
- High ductility, easy to bend and form.
- Non-magnetic, good corrosion resistance.
What is brass?
Brass is an alloy of copper (Cu) and zinc (Zn) , with the zinc content typically ranging from 5% to 45%. Depending on the zinc content, the color and properties of brass can vary.
Outstanding features of brass:
- Color: Light yellow to dark yellow, metallic shine.
- Easy to process, hardness and mechanical strength are higher than red copper.
- Good corrosion resistance, especially in seawater environments.
- May become slightly magnetic when containing high levels of zinc or other elements.

How to distinguish brass from copper
| Criteria | Copper | Brass |
|---|---|---|
| Color | Orange red, pink | Shiny gold, almost like real gold |
| Ingredient | Almost pure copper | Copper + Zinc |
| Electrical/thermal conductivity | Very high | Lower than copper |
| Hardness | Soft, pliable | Harder, easier to machine |
| Main application | Electricity - electronics, precision mechanics | Decoration, manufacturing machine parts |
Quick tips:
- Look at the color: If the metal has a bright red color -> red copper; if it has a yellow shine like yellow gold -> brass.
- Using a magnet: Copper is not attracted, brass can sometimes be slightly attracted if iron is added.
- Tap: The sound emitted from copper is usually deeper and warmer.
