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 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 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. The mass of the same volume is about 15% heavier than ordinary steel.

The red copper is generally called red copper because of its rose red color and purple after the oxide film is formed 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, 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 conductivity and thermal conductivity, excellent plasticity, and is easy to be processed by hot and cold pressure. It is widely used in the manufacture of electrical wires, cables, electric brushes, and special electrolytic copper for electric sparks 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; 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. Brass 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.

Main performance:

1. Room temperature organization

Ordinary brass is a binary alloy of copper and zinc, and its zinc content varies widely, so its room temperature structure is also very different.

2. Pressure processing performance

α single-phase brass (from H96 to H65) has good plasticity and can withstand hot and cold processing, but α single-phase brass is prone to medium temperature brittleness during hot working such as forging, and its specific temperature range varies with the Zn content. The change is generally between 200 and 700°C.

3. Mechanical properties

Because of the different zinc content in brass, the mechanical properties are also different. The mechanical properties of copper vary with the zinc content. For alpha brass, as the zinc content increases, both σb and δ continue to increase.
