1. Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a variety of alloys composed of more than two elements, it is called special brass. Brass parts has strong wear resistance. Brass is often used to make valves, water pipes, connecting pipes for internal and external air conditioners, and radiators.
2. Red copper, also known as red copper, is a simple substance of copper, so named because of its purple-red color. See copper parts for various properties. Red copper is industrial pure copper with a melting point of 1083°C, no allotropic transformation, and a relative density of 8.9, which is five times that of magnesium parts. The mass of the same volume is about 15% heavier than ordinary steel parts.
The red copper is generally called red copper because of its rose red color and purple after forming an oxide film on the surface. It is copper containing a certain amount of oxygen, so it is also called oxygen-containing copper.

The mass of the same volume is about 15% heavier than ordinary steel. Because it has a rose red color and is purple after an oxide film is formed on the surface treatment, it is generally called copper. It is copper containing a certain amount of oxygen, so it is also called oxygen-containing copper.
Red copper has good electrical and thermal conductivity, excellent plasticity, and is easy to be processed by hot and cold pressure. It is widely used in the manufacture of wire cutting, cables, electric brushes, electric spark copper and other products that require good electrical conductivity.
The difference between copper and brass
1. Appearance color
Brass: It is light golden yellow and shiny.
Copper: Rose red, shiny.
2. Ingredients
Red copper: The content of copper has reached 99.9%.
Brass: about 60% of copper; about 40% of zinc parts; some grades contain about 1% of lead, which is impurity.
3. Strength
Brass: higher.
Copper: lower.
4. Density
The density of brass (8.93g/cm3) is mostly used for mechanical bearing lining, and it is wear-resistant. metal castings are often used to make valves and pipe fittings.
Red copper. Pure copper, also known as red copper, has a density (7.83g/cm3), a melting point of 1083 degrees, and is non-magnetic.
