Note: The actual weight per square meter may vary due to manufacturing tolerances in sheet thickness. These tolerances are generally tight for copper and brass but can be more significant for materials like mild steel, leading to slight variations in weight. Additionally, when purchasing sheet metal by the tonne, the actual number of sheets received may vary depending on the exact thickness of each sheet. Buyers should consider these factors when estimating material requirements.
Specific Gravity of Common Sheet Metals
The specific gravity (SG) of a metal is its density relative to water (SG = 1.0 for water). This chart provides industry-standard SG values for common sheet metals, ensuring accurate weight calculations when estimating material requirements.
Why is Specific Gravity Important?
- Helps calculate sheet weight per square meter (kg/m²).
- Useful for material selection in fabrication & manufacturing.
- Ensures accurate costing & shipping estimations.
