bonded metals
Bonded Metals are defined to be composite materials formed by the permanent joining of two or more metallic layers through various bonding techniques such as diffusion bonding, brazing, or adhesive bonding. It increases the mechanical property, corrosion resistance, and aesthetic appeal.

Key Features:
- Bonding Techniques :The predominant techniques are diffusion bonding (a form of solid-state joining), brazing (working with a filler metal), and adhesive bonding (applying a special type of adhesive). The choice of technique depends on the strength, conductivity, and durability desired.
- Strengthening: Bonding metals allows for an increase in strength, thermal/electrical conductivity, corrosion, and abrasion resistance, thus making them candidates for tough applications.
- Applications: In general, the need for high performance has led to bonded metals being used in aerospace, automotive, electronic, and architectural industries.
The bonded metals are significant in that they combine the best properties of different metals to meet particular engineering and design requirements. For instance, in aerospace, bonded metal panels provide lightweight yet durable structural elements that enhance fuel efficiency and safety; in the automotive case, bonded metals are weight-saving to the advantage of strength imparted to vehicle body systems, thus improving performance and efficiency. Therefore, bonded metals also ensure that consumer electronics are durable and aesthetically pleasing in designs such as smartphones and laptops. Constant development of bonding technologies maintains the position of bonded metals as an important material choice for modern-day industries.
