This highly depends on the temperature and the conditions. Heatshields for a space craft are made from lightweight ceramics, suitable for temperatures well above 1000 deg. C. Heat shields for use in more common applications, like a car exhaust system, are made from sheeth-metal. The choice of the metal or alloy being dependent on the environmental conditions.
What else can I help you with?
Is the shield still used today?
Yes, shields are still used today, primarily in law enforcement and military contexts. Modern shields are often made from advanced materials like Kevlar or composite plastics and are designed for protection against various threats, including projectiles and melee attacks. Additionally, shields are utilized in some sports, historical reenactments, and by certain security personnel for crowd control and personal defense.
Why most of the heat exchangers are made use of forced convection?
Better heat transfer than natural convection. When compared to water or liquid cooled heat exchangers, the argument could be made that air is a cheaper cooling medium.
What are manufactured boards?

What does the heat shield do on a spacecraft?
As the name implies, a heat shield shields something from heat. In the case of a spacecraft heatshield, it shields and protects the craft itself from the tremendous amount of heat created by air friction due to the extremely high speed of the craft during reentry into the Earth's atmosphere.
