• When electricity is passed through the cell copper is dissolved at the anode by oxidation, Cu 2+ ions go into the solution. At the cathode, copper is deposited by reduction. • As copper ions move from the anode to the cathode the anode gets smaller as the cathode gets bigger. This is called a redox reaction.

BRASS • Brass for industrial purposes is an alloy of Copper (60%) Zinc (37%) and Lead (3%). • This yellowish colored alloy is used to produce such articles as meter fitting (taps), wood screws, machine screws, electrical components etc.

Types of brasses • Brasses can be classified as follows ▫ α-brasses ▫ α-β brasses ▫ Delta metal
![αbrasses All brasses obtained between o to 39 of zinc content known as α-brasses • All brasses obtained between o to 39% of zinc content known as](https://slidetodoc.com/presentation_image_h/db71dc28c7c798df957145a3d464934f/image-47.jpg)
α-brasses • All brasses obtained between o to 39% of zinc content known as α-brasses, because the resulting alloy consists of crystals of a uniform solid solution of zinc dissolved in copper which is known as alpha solution
![The alpha brasses possess good tensile strength combined with considerably ductile when • The alpha brasses possess good tensile strength combined with considerably ductile when](https://slidetodoc.com/presentation_image_h/db71dc28c7c798df957145a3d464934f/image-48.jpg)
• The alpha brasses possess good tensile strength combined with considerably ductile when cold, making them suitable for producing sheet, strips, wire etc. • These brasses retain high strength in compression at elevated temperatures as compared to alpha – beta brass, and there fore require greater power to hot them.
![αβ brasses All brasses obtainable between 39 to 46 6 zinc content are α-β brasses • All brasses obtainable between 39% to 46. 6% zinc content are](https://slidetodoc.com/presentation_image_h/db71dc28c7c798df957145a3d464934f/image-49.jpg)
α-β brasses • All brasses obtainable between 39% to 46. 6% zinc content are known as α-β brasses, because every resulting alloys consists of a second zinc- rich constituent, namely the beta solid solution, in additional to α-solid solution. • The alpha-beta brasses when cold contain hard beta crystal which increased tensile strength but reduce the ductility
![DELTA METAL This is a high tensile brass produced by adding 3 Fe DELTA METAL • This is a high tensile brass produced by adding 3% Fe](https://slidetodoc.com/presentation_image_h/db71dc28c7c798df957145a3d464934f/image-50.jpg)
DELTA METAL • This is a high tensile brass produced by adding 3% Fe to a composition of the brass, thus overall composition being Cu 60%, Zn 37% and Fe 3%. This brass resist corrosion. Too much iron reduces machinability. • At a temperature of 5500 C this metal can be worked by forging, rolling, stamping or pressing into desired shape.

BRONZES • The term bronze is normally applied to the alloys of copper and tin, but more generally with the additional of other elements such as zinc, nickel, phosphorus, aluminum, lead etc • The composition of Bronze is typically Copper (88%), Tin (10%) and Zinc (2%). • Typical examples of these are phosphor bronze, gunmetal, lead bronze, plastic bronze and nickel bronze.
![The physical appearance of Bronze is a dark reddishyellow colour The • The physical appearance of Bronze is a dark reddish-yellow colour • The](https://slidetodoc.com/presentation_image_h/db71dc28c7c798df957145a3d464934f/image-52.jpg)
• The physical appearance of Bronze is a dark reddish-yellow colour • The copper-tin alloys usually contain 5 to 20%, although most of the commercial bronze contain from 10 to 12% tin, other cast gun metal have 5 to 10% of tin.
![Phosphor bronze Phosphor bronze are coppertin containing 5 to 20 of tin 0 Phosphor bronze • Phosphor bronze are copper-tin containing 5 to 20% of tin, 0.](https://slidetodoc.com/presentation_image_h/db71dc28c7c798df957145a3d464934f/image-53.jpg)
Phosphor bronze • Phosphor bronze are copper-tin containing 5 to 20% of tin, 0. 1 to 1. 5% of phosphorus and rest copper. Phosphorus results in the formation of every hard copper phosphide constituent which improves hardness and wear resistance of the metal.
![GUNMETALS These are alloys of copper tin and zinc with the zinc in GUNMETALS • These are alloys of copper, tin and zinc, with the zinc in](https://slidetodoc.com/presentation_image_h/db71dc28c7c798df957145a3d464934f/image-54.jpg)
GUNMETALS • These are alloys of copper, tin and zinc, with the zinc in small proportions up to 6%(max) Usually, however, the percentage of zinc is limited to 2. 5 owing to the tendency toward brittleness with greater proportions • The zinc improves the casting properties and enable sounder casting to be made. It is also a much cheaper metal than tin so that it uses enables an economy to be affected.

• A typical composition of a gum metal is admiralty gum metal which its composition are Cu 88%, Sn 10% and Zn 2%. • Gunmetals are used for less expensive sand castings than the alloy bronzes where harder and better wearing qualities are required than for brass parts. Typical application of gunmetals include gearwheel, pump casting, bearing bushing and marine fitting.
