Täytemetalleja

Täytemetalleja, also known as fill metals, are a group of metals used in the production of ammunition. They are typically used as a core material within the bullet, providing structural support and improving the bullet's performance. The most common täytemetalleja used in ammunition include lead, copper, and steel.

Lead is the most widely used täytemetalli due to its high density, which contributes to the bullet's weight and velocity. However, lead has been the subject of controversy due to its potential health and environmental impacts, leading to a push for more environmentally friendly alternatives.

Copper is another popular täytemetalli, known for its excellent corrosion resistance and good mechanical properties. Copper-jacketed bullets, where a copper layer surrounds a lead core, are often used in hunting and self-defense applications.

Steel is used in some specialized ammunition, such as armor-piercing rounds, due to its high strength and hardness. Steel-tipped bullets are designed to penetrate armor and other hard materials.

The choice of täytemetalli depends on the specific requirements of the ammunition, including the intended use, the type of target, and the desired performance characteristics. As with any material used in ammunition, the selection of täytemetalleja must balance performance with safety and environmental considerations.
