Copper
Think of copper and you’ll likely think of a metal that is both decorative and useful. But how does it stand up as a building material? Read on to learn more.
Qualities of Copper
Copper is known for the following qualities:
• corrosion resistance
• durability
• its compatibility with other materials
• its natural tint and shades
• excellent thermal and electrical conductivity
• is very workable
• is environmentally friendly and recyclable (in fact, over eighty percent of copper ever mined is still in use)
• fire and pollution resistant
When copper is alloyed with tin, bronze is made. When it is alloyed with zinc, brass is made.
Uses of Copper
Copper is used in a number of ways when it comes to building. It can be used in roofing, for cladding, around windows, and on whole walls. Different finishes are being used to control the colour and patina of the copper. In fact, copper as a building material is growing in popularity.
When used in building wire systems, it is the most efficient, strongest, and most reliable metal available. Because copper is such an effective conductor, it is the best choice for electrical wiring systems. Copper building wire requires less insulation and smaller conduits than other metals with lower conductivity, as metals with lower conductivity need to be larger in diameter than copper to carry the same current. Copper is also strong, resisting stretching, creepy, nicks, and breaks. It is also compatible with all connectors and other devices.
Copper is also used in water pipes as it is easily joined and does not rust easily. It also conducts heat well, making it ideal for hot water pipes. Copper, when used in plumbing, is bacteriostatic. That means that bacteria cannot grow in the pipes, making it a hygienic source of water supply.
Considerations with Copper
Copper as a building material is initially more expensive to install and this could potentially be a disadvantage, depending on your budget. However, the very qualities of copper such as its strength, conductivity, and corrosion resistance means that it will last longer than other materials that you may choose for the same job. Over time, copper may actually work out to be cheaper.
