# Brass plate application

Brass plate application
Among metallic materials, brass not only has excellent extensibility, but also can be processed independently of temperature. Even under severe corrosion conditions, copper plates will automatically form a strong, non-toxic passivation protective film in order to prevent corrosion. This protective film is damaged when automatic repair, strong stability.

Brass plate is easy to work, strong tension. So can do all kinds of deep drawing and bending manufacturing force parts, such as rivets, conduits, radiator parts, etc. At the same time has good mechanical properties, electrical conductivity and thermal conductivity, widely used in hardware, daily electrical appliances and building materials and other industries.

Classification of brass plate
(1) lead brass

The density of lead is insoluble in brass, so it is distributed on the grain boundary as a free particle. Lead brass has α and (α+β) two kinds, α lead brass is affected by lead, so the high temperature plasticity is very low, can only use cold deformation or hot extrusion. And (α+β) lead brass has strong plasticity at high temperature and can be forged.

(2) tin brass

In order to improve the heat resistance of the alloy, the addition of tin can effectively improve, especially the resistance to seawater corrosion.

At the same time, tin can be dissolved into liquid copper to achieve solid solution and strengthening. However, the increase of tin content is not conducive to the plastic deformation of the alloy, so the tin content of tin brass can be controlled in 0.5% ~ 1.5%.

(3) the manganese brass

Manganese has a high solubility in solid brass, so adding 1% ~ 4% manganese without reducing thermoplasticity can effectively improve the strength and corrosion resistance of the alloy. Manganese brass has (α+β) structure, and HMN58-2 is commonly used. It has good performance in hot and cold conditions.

(4) iron brass

As a crystal core, iron can refine the grains and prevent the recrystallized grains from growing, so as to improve the mechanical and technological properties of the alloy. Usually the iron content is controlled below 1.5% effect is the best, iron brass has a structure of (α+β), with high strength and toughness, high temperature plasticity is good, cold state can also be deformed.

How many materials is brass made of  ?
Brass is an alloy composed of copper and zinc, brass composed of copper and zinc is called ordinary brass, if it is composed of more than two kinds of alloy is called special brass.
A variety of alloys is called special brass.

So far, the earliest copper products found in the world are mainly in Western Asia, such as the Zawai Chami region of Iraq, where copper ornaments were found, dating from about 10,000 to 9,000 BC.

Copper ornaments have also been found in the Ali Kashgar region of western Iran, dating from 9,000 to 7,000 BC. Copper needles and cones have been found at the site of Chayoni in southern Turkey, dating from about 8,000 BC. These copper products are natural red copper products, not copper obtained by smelting ore.

From the use of pure copper, to smelting copper ore to obtain pure copper, and then to smelting bronze alloy, human beings have experienced a very long period of exploration, just like the magic world with copper bit by bit to create a sparkling time and space tunnel.
