It is a chemical element also known as tungsten. Along with iron it forms very complex, stable and hard carbides, which withstand very high temperatures. In percentages of 14 – 18%, it provides high-speed steels with which it is possible to triple the cutting speed of carbon steels for tools.
DetailsIt is the maximum stress that a material with elastic properties can withstand without suffering permanent deformations. If stresses above this limit are applied, the material does not recover its original shape when the loads are removed. A material subjected to stresses below its yield limit is temporarily deformed according to Hooke’s law.
DetailsIt is a zinc alloy with aluminum, magnesium and copper. The zamak offers important features like hardness and has high tensile strength. It is a cheap material, has good mechanical strength, plastic deformability and good castability. The disadvantage is that intercrystalline corrosion occurs in cases of temperature with humidity.
