They are conspicuous, too, so they must be made of a naturally elegant-looking material. Tools — Ever wondered what metal your wrenches, pliers, screw drivers, and other house tools are made of? Judging by their physical features, you can easily tell that they are copper-based. Specifically, most of them are made of beryllium copper, a non-sparking and non-magnetic alloy that works well in hazardous workspaces.
Musical Instruments — Copper alloys are also valued for their acoustic quality, especially brass, an alloy of copper and zinc. There are so many brass-based musical instruments that an entire subset of them was named brass. Pipes used to convey water or substances requiring zero-level contamination are often made of copper alloys. It lasts longer, repels mold and mildew, and looks appealing. However, since copper is a little bit more expensive than its galvanized counterpart, you have to be ready to fork out more cash.
Over a hundred different copper-based alloys have been discovered since the industrial revolution, and most of them are massed produced and commercially available. Thanks to reputable copper suppliers like Rotax Metals, you have access to superior materials for your projects.

Copper is the only naturally occurring metal other than gold that has a distinctive colour. Like gold and silver, copper is an excellent conductor of heat and electricity. It is also very malleable and ductile. Copper is also resistant to corrosion it does not rust very easily. Copper is soft but tough.
It is easily mixed with other metals to form alloys such as bronze and brass. Bronze is an alloy of tin and copper and brass is an alloy of zinc and copper. Today copper, because it is such a good conductor of electricity, is used in electrical generators and motors for electrical wiring and in electronic goods, such as radios and TVs. Copper also conducts heat well, so it is used in motor vehicle radiators, air-conditioners and home heating systems.
As copper does not corrode easily it is also used for water pipes. Its malleability means that copper pipes can be bent to go round corners easily, without breaking. Copper sulphate is used as a fungicide to stop plant roots from blocking drains and sewerage systems. The blue-green colour of treated timber is the result of copper naphthanate and copper-chrome-arsenate which have been introduced under pressure to help protect the wood from borers.
Copper is also used for making coins and scientific instruments as well as in decorative applications. There is about 15 grams of copper in a mobile phone and recently copper has been replacing aluminium in computer chips.
As copper does not rust easily and can be easily joined, it is useful for making water pipes and hydraulic systems. The use of copper in water pipes dates back to the ancient Egyptians and the Romans. Copper's ability to conduct heat means it is used for car radiators, air conditioners, home heating systems and boilers to produce steam. It is also ideal for the base of cooking pots. Copper sulphate is used to kill algal blooms in water reservoirs, to protect timber, to stop plant roots from blocking rains and sewerage systems and to kill insects.
Copper production was boosted in the s and s by the need for copper-based fertilisers to aid crop growth in previously unproductive land. The earliest bronzes were natural alloys derived from mineral deposits which also contained tin. Many musical instruments are made from brass. It is also used for decorative pieces, from light fittings to taps and instruments for astronomy, surveying, navigation and other scientific purposes. Old copper utensils displayed in a Jerusalem restaurant.
Copper was the first metal used by people. It was discovered by Neolithic Man about years ago and used in place of stone, as it was far easier to shape. Early coppersmiths in Iran found that heating copper softened it and hammering copper made it harder. Its beautiful colour also made copper attractive for use in jewellery and ornaments. There is evidence that copper was used from early times, a piece of copper tubing used years ago was unearthed by archaeologists from the Pyramid of Cheops in Egypt.
