Steel vs Aluminum Weight Calculator

Here is a comparison table between steel and aluminum weights, considering various types of each metal. The weight values are approximations based on typical densities and common types.

Material	Type	Density (g/cm³)	Density (lb/in³)	Notes
Steel	Carbon Steel	7.85	0.284	Most common type of steel
	Stainless Steel	7.75 – 8.0	0.280 – 0.290	Corrosion-resistant alloy
	Tool Steel	7.70 – 8.0	0.278 – 0.290	Used for cutting and machining tools
	Alloy Steel	7.7 – 8.05	0.278 – 0.291	Combined with other elements for strength
	Mild Steel	7.85	0.284	Low carbon steel, widely used
	Cast Iron	6.8 – 7.8	0.246 – 0.282	High carbon content, brittle
	High-Carbon Steel	7.8 – 7.85	0.281 – 0.284	Strong and hard but less ductile
	Low-Carbon Steel	7.85	0.284	More ductile and malleable
Aluminum	Pure Aluminum	2.70	0.098	Soft, malleable, and ductile
	2024 Aluminum Alloy	2.78	0.100	High strength, used in aerospace
	6061 Aluminum Alloy	2.70	0.098	Versatile, good corrosion resistance
	7075 Aluminum Alloy	2.81	0.102	Very high strength, aerospace applications
	Cast Aluminum	2.66 – 2.80	0.096 – 0.101	Used in automotive and construction
	5052 Aluminum Alloy	2.68	0.097	Good corrosion resistance, marine use
	3003 Aluminum Alloy	2.73	0.099	Good formability, used in cooking utensils
	6063 Aluminum Alloy	2.69	0.097	Architectural applications, good extrudability

Notes:

• Density is the mass per unit volume and is a crucial factor in determining the weight of a material.
• Steel is generally heavier than aluminum due to its higher density.
• Aluminum is chosen for applications where weight savings are crucial, such as in aerospace, automotive, and portable structures.
• Steel is preferred for applications requiring high strength and durability, such as construction and heavy machinery.

This table can help in choosing the right material based on weight considerations for different applications.
