Production Process:

Raw Material Preparation: The first step in producing nickel-copper alloy foam involves preparing nickel and copper powders in the appropriate proportions. Strict control over the composition ensures the desired properties of the resulting alloy.

Mixing and Alloy Slurry Preparation: Nickel and copper powders are mixed according to the designed ratio, and a suitable amount of binder and foaming agent is added. The mixed material forms a slurry used for the subsequent foaming step.

Foaming: The alloy slurry is placed in molds with a foaming agent. Under the action of the foaming agent, the material in the mold expands, forming a foam-like structure. This step can be achieved through heat treatment or chemical reaction.

Sintering: The formed foam structure undergoes sintering to establish strong connections within the alloy. This step helps improve the mechanical strength and stability of the foam.

Post-Processing: Further processing steps may include surface coating, adjusting porosity, or other customized treatments to meet specific application requirements.
