1. Density: Non-ferrous metals are generally lighter in density compared to ferrous metals. For instance, aluminum has a density of around 2.7 grams per cubic centimeter (g/cm³), while iron has a density of 7.87 g/cm³.

2. Strength: Non-ferrous metals can range from being as soft as lead to as strong as titanium. For example, copper and aluminum alloys can achieve high strength levels while remaining lightweight.

3. Corrosion Resistance: Many non-ferrous metals have excellent corrosion resistance, making them suitable for outdoor or marine environments. Examples include aluminum, copper, and titanium.

4. Electrical and Thermal Conductivity: Non-ferrous metals are generally good conductors of electricity and heat. Copper and aluminum are among the most widely used metals for electrical wiring due to their excellent conductivity and relatively low cost.

5. Malleability and Ductility: Many non-ferrous metals are malleable and ductile, which means they can be easily shaped or drawn into various forms without breaking. Examples include copper, gold, silver, and aluminum.

6. Non-Magnetic: Unlike ferrous metals, non-ferrous metals do not exhibit magnetic properties. This makes them suitable for applications where magnetism is undesirable or where non-magnetic materials are required.

7. Special Properties: Certain non-ferrous metals possess unique properties that make them valuable for specific applications. For example, titanium is highly resistant to corrosion and high temperatures, while beryllium has excellent dimensional stability and high thermal conductivity.

8. Biocompatibility: Some non-ferrous metals, such as titanium and certain stainless steel alloys, are biocompatible and can be used in medical implants or devices.

9. Toxicity: Some non-ferrous metals can be toxic, particularly when inhaled as fumes or dust. Proper safety measures and regulations should be followed when working with such metals to minimize any potential health risks.

10. Recyclability: Many non-ferrous metals are recyclable, allowing them to be recovered and reprocessed into new products, contributing to sustainability and reducing the need for primary metal production.

Overall, non-ferrous metals offer a wide range of properties and applications, making them indispensable in various industries and sectors, including transportation, aerospace, construction, electronics, energy, and consumer goods.
