Which one is more expensive, N05500 or Monel 4400?

N05500 is generally more expensive than Monel 4400 because it offers greater mechanical strength and hardness.

N05500 alloy (also known as Monel K-500) and Monel 4400 (UNS N04400) are both nickel-copper alloys that are comparable in corrosion resistance. However, N05500 alloy contains elements such as aluminum and titanium and undergoes specific heat treatment, making it higher strength and hardness. This enhanced performance makes N05500 more suitable in certain applications, especially where higher mechanical properties are required. The following is a detailed analysis of these two alloys:

Composition difference: N05500 alloy contains 2.3%~3.15% aluminum and 0.3%~1.00% titanium. The addition of these elements helps to improve its mechanical strength and hardness.
Performance comparison: The mechanical strength and hardness of N05500 are higher than Monel 4400, but the plasticity is slightly reduced. This means that N05500 will perform better in applications that can withstand greater forces, but may not be as good as Monel 4400 in situations where a high degree of plasticity is required.
Application fields: Due to its superior hot corrosion resistance and long-term structural stability, N05500 is often used to manufacture aeroengine turbine blades and gas turbine blades and other components with operating temperatures below 750 degree .
