Physical Properties
Strength
Copper is a weak metal with a tensile strength about half that of mild carbon steel. This explains why copper is easily formed by hand, but is not a good choice for structures.
Toughness
Copper may not be strong, but it is not easy to break due to its high toughness. This property comes in handy for piping and tube applications, where a rupture can be dangerous and expensive.

Ductility
Copper is very ductile and also very malleable. The electrical and jewelry industries benefit from the ductility of copper.

Conductivity
Second only to silver, copper is not only an excellent conductor of electricity, but also of heat. As a result, copper serves well in applications such as cookware, where it quickly draws heat to the food inside.

Corrosion resistant
Copper is low in the reactivity series. This means that it doesn't tend to corrode. Again, this is important for its use for pipes, electrical cables, saucepans and radiators. However, it also means that it is well suited to decorative use. Jewellery, statues and parts of buildings can be made from copper, brass or bronze and remain attractive for thousands of years.

Antibacterial
Copper is a naturally hygienic metal that slows down the growth of germs such as E-coli (the “burger bug”), MRSA (the hospital “superbug”) and legionella. This is important for applications such as food preparation, hospitals, coins, door knobs and plumbing systems.

Non magnetic
Copper is non magnetic and non sparking. Because of this, it is used in special tools and military applications.
Attractive colour
Copper and its alloys, such as brass, are used for jewellery and ornaments. They have an attractive golden colour which varies with the copper content. They have a good resistance to tarnishing making them last a long a time.

Recyclable
Copper can be recycled without any loss of quality. 40% of the world's demand is met by recycled copper.
Steel
Corrosion resistance
All stainless steels have a high resistance to corrosion. Low alloyed grades resist corrosion in atmospheric conditions; highly alloyed grades can resist corrosion in most acids, alkaline solutions, and chloride bearing environments, even at elevated temperatures and pressures.
High and low temperature resistance
Some grades will resist scaling and maintain high strength at very high temperatures, while others show exceptional toughness at cryogenic temperatures.
Ease of fabricationThe majority of stainless steels can be cut, welded, formed, machined and fabricated readily.
Strength
The cold work hardening properties of many stainless steels can be used in design to reduce material thicknesses and reduce weight and costs. Other stainless steels may be heat treated to make very high strength components.
Aesthetic appeal
Stainless steel is available in many surface finishes. It is easily and simply maintained resulting in a high quality, pleasing appearance.
Hygienic properties
The cleanability of stainless steel makes it the first choice in hospitals, kitchens, food and pharmaceutical processing facilities.
Life cycle characteristics
Stainless steel is a durable, low maintenance material and is often the least expensive choice in a life cycle cost comparison.
Decision Making
We will use both on the renders and see which metal would be the most aesthetically pleasing. If we were to use copper, it would need to be a copper plated steel because steel is a stronger metal and would easily hold the weight of people and any weather condition or pressure against it.
