It is the most commonly used cast iron and the most widely used cast material based on weight. Most cast irons have a chemical composition of 2.5–4.0% carbon, 1–3% silicon, and the remainder iron. Grey cast iron has less tensile strength and shock resistance than steel, but its compressive strength is
Cast iron 4.5% C, ASTM A-48: 130: 200: 7.3 "Liquidmetal" alloy [citation needed] 1,723: ... The ultimate tensile strength of a material is an intensive property ...
It is the most common cast iron and the most widely used cast material based on weight. [2] It is used for housings where the stiffness of the component is more important than its tensile strength, such as internal combustion engine cylinder blocks, pump housings, valve bodies, electrical boxes, and decorative castings.
Specific strength: Strength per unit density (Nm/kg) Specific weight: Weight per unit volume (N/m^3) Surface roughness: The deviations in the direction of the normal vector of a real surface from its ideal form; Tensile strength: Maximum tensile stress of a material can withstand before failure (MPa)
In general: ductile materials (e.g. aluminum) fail in shear, whereas brittle materials (e.g. cast iron) fail in tension (see: Tensile strength). To calculate: Given total force at failure (F) and the force-resisting area (e.g. the cross-section of a bolt loaded in shear), ultimate shear strength is:
Brittle materials, which include cast iron, glass, and stone, are characterized by the fact that rupture occurs without any noticeable prior change in the rate of elongation, [1]: 59 sometimes they fracture before yielding. Brittle materials such as concrete or carbon fiber do not have a well-defined yield point, and do not strain-harden ...
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 ...
Cast iron retains high strength in fires, despite its low melting point. It is usually around 95% iron, with between 2.1% and 4% carbon and between 1% and 3% silicon. It does not corrode as easily as steel.
