The history of man's involvement with copper goes back well over 9,000 years and includes the Bronze Age (3200 BC - 1100 BC) which was named after one of the best known copper alloys. Many of the oldest remnants and artifacts of that era are jewelry and cooking vessels that were made from copper. Copper castings discovered by archaeologists digging in what was ancient Mesopotamia, now known as Iraq, have been tested and found to be 5000 or more years old. Because of its electrical and thermal conductivity, as well as its resistance to corrosion and oxidation, copper continues to be one of the most in-demand metals for casting in today's high tech manufacturing environment. In fact, when projects call for high corrosion and high oxidation resistance as well as superior electrical and thermal conductivity, then copper investment castings are the preferred solution. | |||||||||

The Superior Choice of Casting Techniques - The precision castings process is also the superior choice. Other casting and manufacturing processes such as sand or plaster casting, punch pressing, extrusion or cold bending cannot easily attain the desired shape of the part being created when temperatures or other issues are in conflict with a particular process. Another major advantage of the investment castings process, versus other processes, is that parts that are made with this method are smoother and generally require less machining. This is both a cost and time saver in a large production environment where hundreds or thousands of components are being manufactured. Copper is very malleable and can be rolled out to 1/500 of an inch in thickness. It also has superior ductile properties which enable it to be drawn very thin to create wire no thicker than a strand of hair. Only silver is a better conductor of electricity. Copper also has a built in anti-rust mechanism that is triggered by the presence of excessive moisture. When exposed to moisture it will produce a green film called a "patina" that permanently stops the corrosion process.

Perfect for Delicate and Intricate Needs — The fact that it uses the lost wax method is what makes copper investment castings the right choice for delicate and intricate manufacturing needs. This method has been in use since at least 900 BC and due to the properties of wax, the process essentially enables anything that can be created in wax to be converted to metal.

Ideal for Harsh Environments — Many major industries including the aerospace, petrochemical, automotive, medical, electronics and turbine manufacturers utilize precision castings to make a wide variety of parts. Because of its superior properties, copper investment castings are ideal for components such as thermal heads and conductors, electrical conductors, precision gears, bushings, bearings, fluid valves, nautical vessel propellers and many metal parts that are used in a harsh environments or fresh and salt water. Of course, there are also copper recreational, decorating and jewelry items, many which have intricate designs that are also made from precision castings. The fact that copper transcends the industrial world and has made itself at home in the consumer products market as well, is a testament to the versatility of this multi-functional metal. |
