This video tests the ballistic resistance of 2.5-inch thick 6061 aluminum blocks against high-caliber rounds. A .50 BMG API round penetrated the first block and lodged in the second, while an AP round nearly exited the second block. Even powerful .500 S&W Magnum rounds were stopped by the aluminum, demonstrating its surprising durability against firearm projectiles.

Quick Summary

This experiment tested 2.5-inch thick 6061 aluminum blocks against high-caliber rounds. A .50 BMG API round penetrated the first block and lodged in the second, while an AP round nearly exited the second. Even .500 S&W Magnum rounds were stopped by the aluminum.

Frequently Asked Questions

What type of aluminum was tested for its strength against firearms?

The video tested 6061 aluminum, a precipitation-hardened alloy, using blocks that were 2.5 inches thick. This specific alloy is commonly used in various engineering applications due to its good strength-to-weight ratio.

How did .50 BMG rounds perform against the aluminum blocks?

A .50 BMG Armor Piercing Incendiary (API) round penetrated the first 2.5-inch aluminum block and lodged in the second. A standard .50 BMG Armor Piercing (AP) round penetrated even deeper, nearly exiting the second block.

Can aluminum blocks stop .500 S&W Magnum rounds?

Yes, the 2.5-inch thick 6061 aluminum blocks proved capable of stopping powerful .500 S&W Magnum rounds, including heavy 350-grain and 700-grain loads. The blocks showed significant damage but prevented full penetration.

What is the difference between API and AP .50 BMG rounds in this test?

In this test, the .50 BMG API round penetrated the first block and lodged in the second. The .50 BMG AP round penetrated deeper into the second block, nearly passing through, indicating potentially better penetration characteristics.
