Copper Alloy Investment Casting

Historically, investment casting technology was mainly used for casting: tools, weapons and ornaments. Nowadays this technology is employed in many important manufacturing sectors, both industrial and artistic. Especially copper alloy investment casting, which is perfect choice for electrical connectors, heat exchangers, rivets, fasteners, nuts, bolts, and more.

The propagation of the metal usage skills and cast production is connected with the technology of creating models, moulds and casts. Archaeological studies confirm the knowledge of alloy preparation and the application of advanced methods of mould making. The wax model method, based on melting the wax before the mould is cast, ensures smoothness and precision of the model reproduction as well as thin wall of the cast. Wax model was covered with many layers of clay, dried and fired in the proper temperature to ensure refractoriness and mould durability.

Copper has been mined for thousands of years, dating to prehistoric times. The popularity of this metal is related to its physical properties, mainly its ductility, conductivity and resistance to corrosion. In order to expand on these properties, copper can be alloyed with different materials to create combinations that are capable of being used in a wide range of applications. They are commonly used for plumbing, marine and electrical applications because they provide excellent corrosion resistance, high thermal conductivity and toughness.

Copper alloys have a predominant component of copper and are typically classified as brasses or bronzes. Copper-based investment castings are incredibly versatile, with more than 400 different alloys with different properties. Investment casting is an effective and efficient metal manufacturing process because it allows for tight tolerances and is capable of producing intricate cores and passages. Our copper alloy investment casting parts include but not limited to gears, pumps, bearings, marine fittings. Copper alloys are also selected for their various properties that include electrical conductivity, salt water corrosion resistance and aesthetic appearance.
