Note: Actual weight per square metre may vary slightly due to manufacturing tolerances in sheet thickness. These tolerances are generally tight for copper and brass but can be more significant for materials such as mild steel, leading to slight differences in final weight. When purchasing sheet metal by the tonne, the exact number of sheets supplied may also vary depending on actual thickness.

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 metal weight per square metre (kg/m²).
• Useful for material selection in fabrication and manufacturing.
• Ensures accurate costing and shipping estimations.

Use this chart alongside the sheet metal weight table for calculations.

Material	Specific Gravity	Density (kg/m³)
Mild Steel, Corten, Galv, Zintec, HR4, CR4	7.85	7850
400-Series Stainless Steel	7.75	7750
300-Series Stainless Steel	7.9	7900
Brass (CZ108, CZ120)	8.44	8440
Bronze (Phosphor Bronze)	8.8	8800
Pewter (Lead-Free)	7.3	7300
Galvanized Steel	7.85	7850
Copper (C101, C103)	8.92	8920
Aluminium (1050, 6061)	2.71	2710
Zinc (EN988)	7.20	7200

Frequently Asked Questions

How do I calculate sheet metal weight?

To calculate the weight of sheet metal, use the following formula:

Weight (kg) = Length (m) × Width (m) × Thickness (mm) × Specific Gravity

• Length and width in metres
• Thickness in millimetres
• Specific gravity is the same as density in g/cm³ and varies by material

For example, a 1 metre × 1 metre × 1mm thick copper sheet (SG = 8.92) weighs:
1 × 1 × 1 × 8.92 = 8.92 kg

For quick calculations with custom sheet sizes, you can also use our sheet metal weight calculator, which automatically estimates weight based on dimensions and material type.

What is the standard density used for aluminium in weight charts?

Most aluminium weight charts use a density of 2711 kg/m³, which is standard for Grade 1050A H14 and similar aluminium alloys.

What thickness is 1.5mm sheet metal in gauge?

1.5mm thick sheet typically corresponds to 16 gauge for steel and aluminium. Gauge values can vary slightly depending on the metal type.

Does the chart apply to all metal types?

The chart covers common sheet metals including aluminium, brass, copper, steel and stainless steel. Weight varies depending on the density of the specific material and alloy.

Can I order custom sizes based on these weights?

Yes. We offer sheet metal cut to size for many of the metals listed in this chart. Sheets can be trimmed or laser cut to your required dimensions for fabrication, signage, craft and engineering applications.
