aluminium die casting for high speed in Malawi

Gray Iron – Iron Casting Research Institute, Inc.

Sep 07, 1990  ABSTRACT: Gray iron is the most versatile of all foundry metals. The high carbon content is responsible for ease of melting and casting in the foundry and for ease of machining in subsequent manufacturing. The low degree or absence of shrinkage and high fluidity provide maximum freedom of design for the engineer.

Gray Iron – IspatGuru

May 08, 2014  Gray Iron. Gray iron (also called grey iron) is a type of cast iron that has a graphitic microstructure. It is named after the grey color of the fracture it forms, which is due to the presence of graphite. It is the most common cast iron and the most widely used cast material. Gray iron is one of the oldest cast ferrous products.

Machining Cast iron In a Lathe or Mill - STEAMSHED

Nov 28, 2019  Cast iron machining in a lathe or mill needs a very slow speed to cut it properly – too high and there will be sparks everywhere and your tools will need re-sharpening very quickly. As a general rule of thumb, to get a smoother finish on cast iron, you tend to need a finer tip on your cutting tool with very slow transition along the work.

Cast Iron vs Cast Steel Metal Casting Blog

Aug 04, 2021  Cast iron is often cheaper than cast steel because of the lower material costs, energy, and labor required to produce a final product. Raw steel is costlier to purchase, and it requires more time and attention to cast. When designing cast products, however, it is worth considering long-term use and replacement costs.
