Magnesium offers the lowest density among structural metals, making it highly attractive for weight-sensitive applications. Common uses include:

Automotive and aerospace components to optimise fuel efficiency and performance.
Sports equipment and consumer electronics where lightness enhances usability and portability.
Alloys used in rapid-prototyping and engineering experiments due to good castability.

Because magnesium is highly reactive, its processing requires careful handling, but advances in protective coatings and alloying have expanded its practical uses significantly.

Lead and Tin: Traditional Roles with Modern Considerations

Lead has historically been used for shielding against radiation, batteries (lead-acid) and sound damping, while tin has found roles in coatings, ceramics, and soldering alloys. However, lead is increasingly restricted in many consumer products due to health concerns, and tin is often implemented in small but critical quantities for protection against corrosion and for reliable solder joints. In today’s market, the use of these metals is carefully managed to balance performance with safety and environmental considerations.

Brass and Bronze: Copper Alloys with Distinctive Properties

Bronze (copper with tin) and brass (copper with zinc) are two well-known copper-based alloys. Their uses are defined by their specific properties:

Bronze: Hardness, wear resistance, and hardness stability under heat make it ideal for bearings, bushings, sculpture, and musical instruments.
Brass: Predictable machinability, pleasing aesthetics, and acoustic properties suit plumbing fittings, decorative hardware, musical instruments, and architectural features.

These alloys respond well to shaping processes and maintain consistency across production runs, which is why they persist in engineering and design.
