Aluminum vs. Steel - 9mm penetration test
This video demonstrates a ballistic test comparing the penetration resistance of aluminum and steel plates against 9mm ammunition. The HK P30 pistol was used to fire rounds at both materials, clearly showing steel's superior ability to stop projectiles compared to aluminum. The test highlights practical material differences relevant to ballistic applications.
