Brass
Brass

Brass is basically two-component copper (Cu) and zinc (Zn) alloys. In order to improve the properties of brass such as workability and corrosion resistance, other chemical elements are added in smaller quantities, thereby obtaining "special meshes". It can be said that the best mechanical properties are achieved with a zinc content of about 40%. By adding zinc, the tensile strength of the brass is increased, and it reduces electrical and thermal conductivity. The basic application of brass is in machine processing, construction, architecture and manufacturing of parts for the electrical industry. It also has great uses in the production of ammunition and in the military industry. The CuZnPb3 alloy is used for hot processing in the process industry, in the electrical industry and in the manufacture of machine tools. The alloy MsZn37 (Ms63) is the most important alloy for cold processing as well as for semi-finished products obtained by pulling, rolling or pressing. Meaning is an inevitable segment of the modern industry. By adding a third component, such as aluminum, nickel, or lead, its properties of strength, corrosion resistance and cutting edge on the machines are enhanced. Any brass product can be recycled. Messing products produced by recycling have the same characteristics and characteristics as they are derived from primary raw materials and therefore have an extremely important ecological significance.

Composition and application of the most important types of brass:

Name Designation  Copper Alloys  Application

Yellow tomb CuZn20 19... 22 %Zn Electrical engineering, decorative items, metal hoses
Yellow tomb CuZn30 31... 28 %Zn  Condensing and other heat exchanger pipes, for deep drawing of the shell
Crushing Brass CuZn37 35... 28 %Zn Base alloy for cold deformation: pipes, sheets, springs, screws
Brass for forging CuZn40 38... 41 %Zn For deformation in the hot and cold state: wires, hardware, locks, screws
Hard brass CuZn30Pb2

40... 44 %Zn  +  2%Pb

Basic alloy for processing by cutting off the chip: engraving brass, timing gear, screw, profile

Copper
Copper

Copper belongs to heavy metals. Its specific weight is about 8.93 kg / cm3 and the melting temperature is 1083ºC. Copper has no allotropic modification properties.

Bronze
Bronze

Bronze refers to the alloy of copper and tin. However, more broadly, it does not have to be a double alloy or a tin must be an alloying element (therefore, in addition to tin, there are also aluminum, lead, manganese and other bronze.
