Tip:
The data is alphabetically sorted to ease its review.
Remarks:
- Tensile Strength: Measures the maximum stress that a material can withstand before breaking while being stretched or pulled.
- Flexural Modulus: shows material’s stiffness when it is bent.
- Impact Strength: indicate the material’s ability to resist a high-force or shock load without fracturing.
- Density: The mass per unit volume of a material. It can be compared to the density of water which is 1.00 g/cm3.
- Melting Point: The temperature at which the material changes from a solid to a liquid state.
- Price per kg: Approximate cost of the material per kilogram, which can vary based on market conditions and supplier.
