Types of Brass

Brass basically refers to a yellowish alloy of copper and zinc, which moreover also comprise a little bit amounts of other metals, but generally 67 percent copper and 33 percent zinc. Brass has been widely used in the manufacturing of ornaments, objects, or utensils and so on. As a consequence of aforesaid discussion on can conclude that brass is a only term which is used for the alloys of copper and zinc.

The strength and versatility of brass objects solely depend upon the of the proportions and quantity of the zinc and copper. While copper and zinc blended together efficiently, it gives birth to brass. At a world level Brass has been often termed as substitutional alloy.

On the bases of brass's usage, application etc. we can categorize the types of brass as mentioned below. Following are the major Brass types :-


Admiralty Brass :-

The type of brass consists 30% zinc and 1% tin which suppresses dezincification in most environments.

Alpha Brasses (Prince's Metal) :-

This type of brass has been usually used in forging, pressing etc. and it consists of less that 35 % zinc. This type of brass is capable of being shaped or formed into other objects. Furthermore, they contain only one phase, with face-centered cubic crystal structure.

Alpha-Beta Brass :-

Alpha-Beta Brass has been also known as Duplex Brass. It consists zinc form 35 % to 45 % zinc and is suitable for hot working. It usually comprises both ? and ?' phase that is the ?'-phase is body-centered cubic and is harder and stronger than ?. Alpha-beta brasses are usually worked hot.

Aluminum Brass :-

As this type of brass encompasses of huge amount of aluminum, aluminum brass has been widely known for its ability to improve corrosion resistance.

Arsenical Brass :-

As it consists of an addition of arsenic and frequently aluminium, arsenical brass has been widely used for boiler fireboxes.

Beta Brasses :-

Beta brasses usually consists of zinz quantity upto 45 % to 50 % and these can only be worked hot. Beta brasses are relatively harder, stronger, and suitable for casting.

Cartridge Brass :-

It is a brass type consisting 30% of zinc brass and having good cold working properties.

Common Brass :-

Also called as Rivet Brass, common brass is a 37% zinc brass, cheap and standard for cold working.

DZR Brass :-

DZR brasses are having relatively small percentage of Arsenic. It is a Dezincification resistant Brass.

High Brass :-

High brass incorporates 65% of copper and 35% of zinc, that further makes it highly preferred item to be used in screws, springs, rivets and many more. High brass has a high tensile strength.

Leaded Brass :-

Leaded brass is generally an alpha-beta brass having an addition of lead. It possesses superb machinability. One can put these in machineries at superb ease.

The aforesaid types of brass are among the few of large varieties of brass that are available in the market. Apart from above mentioned types of brass, there also exists a never ending list, which is used for different types of uses and applications.
