C95500 vs C95800

When choosing the right material for your project, understanding the differences between different types of copper alloys is crucial. Two of the most commonly used copper alloys are C95500 and C95800. These alloys are similar in many ways but have notable differences that can impact their suitability for different applications. This blog post will explore these differences in detail to help you make an informed decision.

Difference Between C95500 and C95800

C95500 and C95800 are both cast bronze alloys that are commonly used in a wide range of industrial and commercial applications. The main difference between these two alloys lies in their composition. C95500 is a high-strength aluminium bronze alloy that contains around 81% copper, 10% aluminium, 5% nickel, and 4% iron. On the other hand, C95800 is a high-strength nickel aluminium bronze alloy that contains around 79% copper, 10% aluminium, 9% nickel, and 2% iron.

One of the main benefits of C95500 is its excellent resistance to corrosion and stress cracking. This makes it an ideal choice for marine and chemical processing applications where exposure to harsh environments is common. In addition, C95500 offers good machinability and weldability, making it easier to work with than other alloys that exhibit similar properties. However, C95500 is not recommended for applications where it will be subjected to high temperatures, as it tends to lose its strength and flexibility at temperatures above 400°F.

C95800, on the other hand, is a highly versatile alloy that offers excellent strength, corrosion resistance, and wear resistance. It is often used in environments that require high strength, such as oil and gas, aerospace, and marine applications. Unlike C95500, C95800 retains its strength and flexibility at high temperatures, making it suitable for high-temperature environments. Additionally, it is often used in applications that require high wear resistance, such as bearings and bushings.

Regarding physical properties, C95500 and C95800 have similar densities and thermal expansion coefficients. However, their mechanical properties differ significantly. C95500 has a higher ultimate tensile strength, yield strength, and hardness than C95800. This makes it a better choice for applications that require high strength and durability. On the other hand, C95800 has a higher elongation at break and is more ductile than C95500. This makes it a better choice for applications requiring flexibility and toughness.


Choosing the right material for your project ensures its success and longevity. C95500 and C95800 are excellent bronze alloys offering various benefits and properties. However, they differ in composition, mechanical properties, and suitability for different applications. By understanding these differences, you can make an informed decision and choose the right alloy for your needs. Whether you need high strength, corrosion resistance, wear resistance or a combination of these properties, there is an alloy that will meet your requirements.
