What are the properties of cast metal?
Metal castings quality is determined by the casting properties of the metal:
- Fluidity.
- Shrinkage. Shrinkage cavity. Shrinkage porosity.
- Surface quality.
- Resistance to cracks formation.
What is cast iron and its uses?
As a result of its good tensile strength and ductility, malleable cast iron is used for electrical fittings and equipment, hand tools, pipe fittings, washers, brackets, farm equipment, mining hardware, and machine parts. A common classification for malleable cast iron is ASTM A47.
What is the hardness of cast iron?
For ductile cast iron ASTM A536 60-40-18, its 130-180 BH, 65-45-12 is 160-210 BH, 70-50-05 is 170-230 BH, 80-60-03 is190-270. However, according to the experience of Dandong Foundry in China, the hardness of cast iron should be controlled under 220 BH.
Is cast iron ductile?
It is a material with good moldability and it is very ductile. The material is also known as nodular cast iron or GS cast iron.
What type of material is cast iron?
alloy
cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus.
What are advantages of cast iron?
Cast iron cookware can go anywhere.
What is the density of cast iron?
Known density of selected metals and alloys
| Metal or alloy | Density (g/cm3) |
|---|---|
| Iron (grey cast) | 7.20 |
| Tin | 7.30 |
| Steel (carbon) | 7.86 |
| Stainless steels | 7.65–8.03 |
What are the important qualities of a casting material?
Castability of Casting Alloys Being cast with desired quality, an alloy must have various characteristics including ease of feeding, fluidity (flowability), low hot tearing tendency, low porosity caused by gas dissolution, no macrosegregation, no tendency to solder to the die, and no tendency to form sludge.
Is cast iron a brittle material?
Cast iron is harder, more brittle, and less malleable than wrought iron. It cannot be bent, stretched, or hammered into shape, since its weak tensile strength means that it will fracture before it bends or distorts.
What are uses of cast iron?
Cast iron is especially used to make stoves which can be heated with coal or wood. It is also used to make frying pans. Further, the spoons, forks and plates are made of stainless steel. The steel is also used to make the frame of stoves to give strength and an attractive bright appearance to the stoves.
What are elements in cast iron?
Increases strength and hardness but decreases ductility and weldability.
What are the mechanical properties of iron?
a portion is liable to become mechanically distributed through the mass of iron or steel in the state of an infusible powder, consisting of manganese in a low etate of oxidation, and injures the mechanical properties of the metal. But when oxide of
