Gray Iron Sand Casting

Short Description:

Material: Gray Iron GG25, EN-GJL-250, HT250

Casting Process: Resin Coated Sand Casting

Weight: 18.50 kg

Application: Agricultural Machinery

Gray Iron Sand Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other metal-forming processes. Thanks to its ease of machining, high compressive strength, better thermal conductivity and excellent vibration absorption, the gray cast iron is one of the most widely used casting metal for a very long time, even in current industry production.
