That being said, cast iron has a far greater thermal expansion coefficient and as the current article says, burrs, and is not useful in a laboratory environment not set up to create and handle master gages. In 98.5% of laboratory settings, a cast iron surface master is more detrimental to accuracy than a granite surface plate.
The cast iron was aged to reduce stress in the metal in an effort to decrease the likelihood of the plate twisting or warping over time. Cast-iron surface plates are now frequently used on production floors as a tool for lapping granite surface plates to achieve certain grades of accuracy. The metal allows itself to be impregnated with the ...
Protective metal plates that became available when cast iron was developed enabled fires to be placed against walls without danger to the fabric of the building. The other function of the fireback is to act as a radiator of stored heat. The metal is heated by the fire, and then that heat is radiated into the room.
In 2002, Lodge became the first cast-iron cookware manufacturer to season their products in the foundry. [6] [7] In 2013, Lodge started their carbon steel cookware line making high-quality carbon steel cookware. [8] Lodge introduced a line of enameled cast-iron cookware in 2005; this was to match the ability of European manufacturers' abilities.

Cast iron is a poor heat conductor compared to copper and aluminum, and this can result in uneven heating if a cast-iron pan is heated too quickly or on an undersized burner. [7] Cast iron has a higher heat capacity than copper but a lower heat capacity than stainless steel or aluminum. [ 8 ]
Cast iron is made from pig iron, which is the product of melting iron ore in a blast furnace. Cast iron can be made directly from the molten pig iron or by re-melting pig iron, [4] often along with substantial quantities of iron, steel, limestone, carbon (coke) and taking various steps to remove undesirable contaminants.
Ductile iron is used in many piano harps (the iron plates which anchor piano strings). Ductile iron is used for vises. Previously, regular cast iron or steel was commonly used. The properties of ductile iron make it a significant upgrade in strength and durability from cast iron without having to use steel, which is expensive and has poor ...
