• Enhanced Strength Compared to Pure Zinc: The inclusion of aluminum particles in ZnAl20 elevates its strength compared to pure zinc powder. This translates to improved load-bearing capacity and better resistance to mechanical wear. Imagine ZnAl20 as a zinc warrior, fortified with aluminum to withstand greater stresses.
• Good Electrical Conductivity: While not a champion conductor like copper, ZnAl20 exhibits decent electrical conductivity. This property makes it suitable for applications requiring the passage of electricity, such as conductive coatings and electromagnetic shielding. Think of ZnAl20 as a bridge, allowing electrons to flow reasonably well across its metallic network.
• Low Melting Point: Compared to many other metal powders, ZnAl20 boasts a relatively low melting point. This characteristic makes it ideal for processes like thermal spraying and metal injection molding (MIM). During these processes, ZnAl20 particles readily melt and flow, enabling the creation of desired shapes and coatings.

This means it can react with oxygen in the air and form oxides, potentially affecting its properties. If your application involves high-temperature environments, ZnAl20 might require additional protection or alternative materials might be a better choice. Imagine ZnAl20 as a metal powder that needs a heat shield at extremely high temperatures to prevent it from reacting with oxygen too readily.
• Limited Formability: ZnAl20, once processed into a solid form, might exhibit limited formability compared to some other metals. This means it might not be ideal for applications requiring extensive bending or shaping after solidification. Think of ZnAl20 as a more rigid material once set, not as easily bendable as some other metals.
• Moisture Sensitivity: ZnAl20 can be sensitive to moisture. Exposure to moisture can lead to the formation of oxides and affect the flowability of the powder. Proper storage and handling are crucial to maintain the integrity of ZnAl20 powder. Imagine ZnAl20 as a bit like a fussy teabag; it needs to be kept dry to perform optimally.
