Copper has been mined for thousands of years, dating back to prehistoric times. The metal's popularity has been linked to its physical properties, primarily its ductility, electrical conductivity, and corrosion resistance. To extend these properties, copper can be alloyed with different materials to create combinations that can be used in a wide range of applications. Copper is a base metal with the atomic symbol Cu.
Copper alloy is a metal whose main component is copper. Copper-based investment castings are used in a wide variety of applications, with more than 400 alloys with different properties.

Advantages of Copper-based Alloy Investment Casting
Since there are so many copper-based alloys, it makes sense for you to choose the right one for your needs. While each alloy has its own properties, they often share similar advantages that can help you make the right decision:
preservative
good ductility
Easy post-casting processing
low wear rate
High thermal and electrical conductivity
Self-lubricating bearing quality
Copper-based investment casting is incredibly versatile, so it's used in a wide variety of applications, such as marine propellers, plumbing and electrical wiring. We can investment cast any part you need from copper based alloys.

Types of Copper-Based Alloys
bronze
alloy of copper and other metals such as tin (about 12% composition), aluminium, manganese, zinc, and silicon, usually yellow/brown in color; melting point varies with alloying elements, but is usually around 950 o C.

For thousands of years, bronze has been used to cast metal objects such as weapons, jewelry, and artwork, but in modern times, these alloys are used in many applications such as bushings, bearings, gears, marine propellers, and other marine applications.

brass
G is usually an alloy of copper and zinc (can vary from a few percent to 40%) and is usually bright yellow/yellow-reddish brown; its melting point will vary depending on the alloying element, but tends to be between 900 o C and 940 o C Between C. Brass is a general term that can encompass many different grades, one of the most popular being nickel silver, made of copper, nickel, and zinc - it's not brassy in color, it's silvery.
Brass alloys are used in the production of musical instruments, plumbing components, decorative valves, locks and tools for non-sparking applications such as explosive atmospheres.

copper and nickel
These two also tend to combine. This is because the resulting alloy is strong and highly resistant to corrosion, mainly marine corrosion. The strongest alloy made from copper is beryllium copper, which has many similar properties to high-strength alloy steels, only more resistant to corrosion over time.
