Aluminum foil is a versatile material used in cooking, packaging, and industrial applications. One of its most important properties is its melting point, which determines how it behaves under heat. Understanding the aluminum foil melting point can help you use it safely and effectively in various applications.

What Is the Melting Point of Aluminum Foil?

The melting point of pure aluminum is approximately 660.3°C (1220.5°F). However, household aluminum foil is often made from alloyed aluminum, which may slightly alter its melting point depending on its composition. Generally, aluminum foil starts to soften at lower temperatures (around 600°C or 1112°F) before fully melting.

Does Aluminum Foil Melt in the Oven?

Standard household ovens typically reach temperatures between 120°C to 250°C (250°F to 480°F), which is well below aluminum’s melting point. Therefore, aluminum foil does not melt in a conventional oven under normal cooking conditions. However, prolonged exposure to high heat (such as in a broiler or grill) can cause it to weaken or discolor.

Why Aluminum Foil Doesn’t Melt Easily

• Aluminum has high thermal conductivity, distributing heat quickly.
• Its oxide layer provides additional heat resistance.
• Most kitchen appliances do not reach extreme temperatures needed for melting.

When Can Aluminum Foil Melt?

While aluminum foil is heat-resistant, it can melt under extreme conditions:

• Direct flame exposure (e.g., over a gas flame or in a welding torch).
• Industrial furnaces reaching temperatures above 660°C (1220°F).
• Accidental placement in high-temperature processes, such as metalworking.

Safety Tips for Using Aluminum Foil with Heat

1. Avoid open flames – Aluminum foil can melt or catch fire if exposed directly to flames.
2. Do not use in microwaves – Foil can spark and cause fires in microwave ovens.
3. Check grill temperatures – Some grills can exceed safe heat levels for foil.
4. Use heavy-duty foil for high heat – Thicker foil withstands higher temperatures better.

Conclusion

The aluminum foil melting point of 660°C (1220°F) ensures its stability in most cooking scenarios. While it won’t melt in a standard oven, extreme heat sources should be avoided. Understanding these properties helps ensure safe and efficient use of aluminum foil in kitchens and beyond.
