Final answer:
Amalgams are higher in compression strength but weaker in tensile strength and flexural strength compared to composites or glass ionomers.
Step-by-step explanation:
Amalgams, which are used by dentists to fill cavities, have higher compression strength compared to composites or glass ionomers. However, they are weaker in tensile strength. Tensile strength is the ability of a material to resist breaking under tension or pulling forces. Amalgams are also weaker in flexural strength, which is the ability of a material to resist deformation when subjected to bending. However, they have good hardness and elasticity properties.
