Classification of brass:
In general the brass is classified into three broad categories which differ in its content ratio and proportions.
The Alpha brass contains zinc in 35% and contains 65% of copper. This is considered as the high quality brass which will be easy to bend, roll and work with. It has also got more corrosion resistance.
Alpha Beta Brass:
The brass which contains more zinc of about 35%-45% percent which is almost 55%-65% of copper. It is similar to pure brass Aluminium in which silicon,tin are added in addition. This is less flexible than the alpha brass.
This type of brass contains the combo of 45%-50% percent zinc with 50%-55% of copper and it’s too hard to work with in making things out of it.
~Besides these three main categories the other categories include gamma brass and white brass.
Other materials used in Brass:
In addition, materials like tin, arsenic, silicon, manganese, phosphorus may be used in a very small amount in the making of Brass.
Basic properties of brass:
Brass contains the ability to withstand for a long period of time holding a strong durability. As both copper and zinc is a metal with no iron content it has got a great durability. Though it’s bright and shiny appearance fades away(can be polished again), that in no way will affect its durability and usage.
As the molecules present in copper have the power to kill the harmful bacteria and microbes, using them in things of our routine life will help to protect through its antibacterial properties.
Beauty to home, Aesthetics, Decorative:
Besides other bronze and copper things, brass has got a little more attractiveness because of its golden color shade, it is mostly chosen for aesthetic purposes.

Various kinds and types of finish can be brought out of it such a bright finish, antique finish, matte finish, brushed etc.
-Color:– Brass is of bright golden color in appearance and may vary depending on the amount of other metals mixed with it.
-Malleability:- It has the malleability which can be Shaped or extended and easily to work with, where coldwork can also be applied to it. (plates, sheets)
-High Conductivity:- Brass is a good conductor of heat and electricity which transfers high electricity voltage without getting overheated.
-Corrosion resistance:- Brass has got the high power of corrosion resistance. Though it gets into contact with regular moistures and salt water, it can withstand from getting oxidation.
-Fatigue resistance:- Continuous or a lot of usage, may lead to weakness in metals. unlike other metals brass is resistant and highly tolerated towards the fatigue. Aesthetic appeal
-Acoustics:- The brass is mostly used in musical instrument and making bells as it creates sound sharper with smooth tone than the other metals which last for a bit longer
~In manufacturing process brass have got good Machinability, Tensile strength, workability and natural elegance
~Brass is also eco friendly and Recyclable, hence making sure about the environmental welfare.
Maintenance of Brass:
According to the maintenance of brass, its quality and life time can be extended for a long period of time. Here are some basic steps in maintenance of Brass.

The aluminum brass contains 77% copper, 20 % zinc and 2% aluminum which is also corrosion resistant. Things like Heat exchangers, condensers are made out of it.
Cartridge brass is Mainly utilized to manufacture ammunition cartridges which contains 70% copper and 30% zinc, that lies under alpha brass classification
This type of brass contains high tensile strength which has the combination of 65% copper and 35% zinc that is used to make bolt,screws and rivets etc.
The gilding brass is the Softest brass of all types which carries 95% copper and 5% zinc and it looks like a reddish colour similar to the appearance of pure copper.
This type of brass as the name itself implies is the content in which lead is added to brass. It is mostly used by the Electronic and industrial manufacturers.
