Coppers in a wide collection of alloys each with chemical composition and properties distinct from the others. Besides zinc, tin and nickel, others like aluminum and lead are among the alloying elements that help achieve different purposes like strength, machinability, corrosion resistance and conductivity. Brass and bronze which are primarily made of copper in the form of copper-tin alloys and copper-zinc alloys, respectively, are the main types of this metal. Brass charts and tables makes possible the boundaries of alloy composition, characteristics, and applications and thus helps in material selection in the manufacturing processes. Supporting documentation (specification, manufacturing process, usage guidelines) are important and these are the most commonly used references for engineers, metallurgists and manufacturers. Recognizing the multiple variations of copper alloys is what industries operating in the electronics, construction, marine, and automotive sectors require to make material selections that would best respond to diverse performance criteria.
Copper proves to be an exceptionally adaptable metal getting made in different grades with various chemical compositions aimed for various uses. Typically, level of copper is defined either based on purity or composition of valuable elements. An Example includes Electrolytic Tough Pitch (ETP) copper that has minor impurities which may be used in electrification process. While the kind A polyvalent oxygen free high conductivity copper (OFHC copper) has an even higher degree of purity used in electrical and electronic high-intensity applications, this kind of copper material does not possess a good impact on keen on beauty buildings. Apart from the copper grades there are also alloys with relatively high corrosion reisstance or strength. Selecting the right grade brings on perfect work performance and helps to keep equipment working longer in many sectors, from electronics to building.

Advantages:
Excellent Electrical Conductivity: Copper tops the popularity chart because of its high electrical conductivity level that enables it to be applied in power distribution, wiring and transmission lines such as in homes and industries.
Superior Thermal Conductivity: The high thermal conductivity feature of the copper is crucial to the effective release of heat from heat exchangers and cooling systems.
Corrosion Resistance: Copper being renowned high level of anti-corrosion in atmospheric and marine environment, prolongs its life much.
Malleability and Ductility: Copper is capable of being reshaped and drawn or rolled into a form without breaking by virtue of its being ductile and malleable together, a characteristic that adds to its structural strength.
Recyclability: Non-ferrous copper is the greatest recyclable material, approximately 90% of global demand is purchased from secondary sources, therefore, to lessen the footprint and save the resources.
Disadvantages:
Susceptibility to Oxidation: The brass as an oxidation-active metal gradually develops discoloration through the tarnish or patina which can tamper the attractiveness of the metal in certain instances.
Softness: While copper's unique flexibility and workability would fall under its advantages, the inherent softness would cause a dent or tear under very strong stresses or forces.
Cost: Often the price of copper is said to be very high particularly in large-scaled projects— this can reduce copper use especially in projects with low budgets.
Weight: Copper shows a greater density than the well-known aluminum, and as a result, weight per linear volume is increased; at the same time, it is important for applications where weight is a critical factor.
Compatibility Issues: Copper is prone to corrosion with some chemical compounds in certain environments is applicable and therefore suitable coatings and method have be performed to prevent corrosion.
