What is the water content in light to medium size malleable iron castings?
View Answer Explanation
Refractory materials are basically used for strengthening the casting materials used in the casting process.
Refractories are generally inorganic non-metallic materials which can resist very high temperature.
Silicon carbide is widely used as refractory material in the mould making for casting processes.
Refractoriness of a material should always be greater than its application temperatures.
What is the amount of green permeability in light to medium size malleable iron castings?
In general, titanium is denser than steel due to compactness in grain structure of titanium.
Titanium alloys have melting point greater than that of steels.
In light to medium size malleable iron castings, lake sand constitutes of 30 parts.
Titanium is a toxic material which can also be affected by the attack of chlorides or mineral acids.
The properties of titanium can remain constant with abrupt variations in the temperature of a material.
