Copper investment casting parts find applications in electrical engineering. The capability of copper to retain electrical conductivity close to 95% makes it ideal for applications of electrical transmission. Copper investment casting offers flexibility in designing parts according to various applications. The flexibility of investment casting to easily combine several assembly parts into a single continuous structure and to cast any design complexity makes it the choice of various casting applications. |

The Oldest Metal Casting Technique Copper investment casting is the oldest metal casting technique and was used in India, China and Egypt over 5,000 years ago. Pure copper doesn't support free casting, but when mixed with tin or lead it becomes easily cast-able. Egyptians discovered that even before they began building the pyramids. Ancient Egyptians used bee-wax to form the structure then covered it with clay. That was then placed into a fire to melt away the wax. The clay would harden with a cavity in the shape of the bee-wax model. The copper would then be melted and poured it into the cavity, which would later be recovered as a sculpture. |

Takes Away the Need of Welding Copper investment casting can conceivably reduce the weight of such structures by reducing the number of parts. It also takes away the need of welding and joining together different parts, with the most visible difference being the absence of nuts, bolts, and fasteners.

It Has Various Commercial Applications Although copper investment casting is widely regarded as the method of sculpture and art-works, it has various commercial applications too. Investment casting is the technique that allows the production of mechanical parts with thin wall capabilities and good finish. Today, the applications of copper castings are there in pump parts, machine tool parts, pipe fittings, etc.The Ideal Solution Investment casting parts and structures have high strength and mechanical properties, and are seldom susceptible to worn out fatigue. The mechanical properties and microstructure of the alloys can be easily controlled by the setting time, as rapid cooling techniques produce excellent strength casting parts. The selection for copper cast alloys is literally endless and the metallurgical and physical properties vary according to the type of alloy. |
