These materials are Iron-Carbon alloys with high percentages and are called foundries because this is the industrial manufacturing process of them.
The higher percentage of Carbon means that the melting temperature of these is much lower than that of steels and also achieves a greater fluidity of the liquid material, which allows the filling of parts of smaller thicknesses and complicated shapes, that is, they have better collability.
On the other hand, the lower melting temperature allows the metal-mold interaction to be less aggressive and consequently healthier parts can be obtained.
Their low cost, and excellent collability, have led to an extensive development of these alloys in applications such as: engine blocks, piston liners, gears, valve bodies, automotive parts, and many other parts for machinery.
Our TVH® TV25 grey iron bars are one of the most widely used ferrous materials and their name is due to the appearance of their surface when broken. This ferrous alloy generally contains more than 2% carbon and more than 1% silicon, as well as manganese, phosphorus and sulfur.
A distinguishing feature of gray iron is that carbon is generally found as graphite, taking on irregular shapes described as “flakes.” This graphite is what gives the grey colour to the breaking surfaces of parts made of this material.
