Aluminum is not as hard as some other metals, such as steel or titanium. It is relatively soft and lightweight compared to these metals.
Brass is harder than some metals like aluminum and copper, but not as hard as others like steel or titanium.
Spoons are not soft, but they are smooth. They are made out of hard metals like aluminum, steel and other metals.
I think it is because metals are non-porous, with more dense and compacted molecules compared with water, wood or other porous materials.

- metals have metallic bonds- metals have a high density compared to liquids- metals are generally hard
Hard metals are materials that have high strength and resistance to wear and deformation. They are different from other materials in terms of their physical properties because they have a higher melting point, greater density, and are more difficult to shape or deform. Additionally, hard metals tend to be more brittle and have a higher level of conductivity compared to other materials.
Alkali earth metals are relatively soft compared to transition metals, like iron or copper. They can be cut with a knife due to their low hardness.
The main metals used in making a blender are stainless steel and aluminum. Stainless steel is often used for the blades and the casing due to its durability and resistance to corrosion. Aluminum is commonly used for the motor housing and other components because it is lightweight and helps with heat dissipation.
it is a common observation that metals of group 1 i.e., li,na,k,rb,cs and group 2,be,mg,ca,sr,ba are soft.similarly the metals of p-block elements in lower parts of groups are also soft but harder than alkali and alkaline earth which are s-block. the metals of d-and f-block elements are called hard metals.
Uranium is a heavy metal that is typically classified as a ductile metal, meaning it can be easily shaped or stretched. However, it is not as malleable as other metals like gold or copper, giving it a relatively hard texture compared to those metals.
Barium is a soft, silvery metal that is easily cut with a knife. Its hardness is relatively low compared to other metals.
The thermal conductivity of hard core depends on the specific material composition. Generally, hard materials like metals have higher thermal conductivity compared to softer materials. For example, metals like copper and aluminum have high thermal conductivities, while materials like plastics have lower thermal conductivities.
