Overview
IMPA 872323 Materials for air vent heads
The main body of the IMPA 872323 air vent head is gray cast iron, which is the most used type of cast iron. Gray cast iron is generally classified as a brittle material, but it still has a certain absorption of external deformation work and a certain toughness of the material. Its carbon content is generally 2.8%~4.0%, because of its casting performance and good process performance and other characteristics, it is widely used in more complex structure castings, and even for pouring containers under pressure.
