For manufacturing, we use the sheet material processing can be anyone of your choice:
Bronze - an alloy of copper, usually with tin as the main alloying element, but applied and alloys with aluminum, silicon, beryllium, lead and other elements, except for zinc and nickel. Alloys containing zinc and nickel have been called shpiatr and are not bronze, but it is a cheap imitation. The name "Bronze" comes from the Italian. bronzo, which, in turn, was either from the Persian word «berenj», meaning "copper" or the name of the city of Brindisi, from which the material was delivered to Rome.
Depending on the doping of tin bronze known, aluminum, silicon, beryllium, etc. All can be divided into bronze, pewter and tinless. The density of bronze, depending on the type of 7.5-8, the melting temperature of 930-1140 ° C;
Ferrous metals - iron and its alloys (steel, ferroalloys, cast iron), in contrast to other metals, known as colored. For ferrous metals also include chromium, manganese and vanadium, are primarily used in the manufacture of iron and steel. Ferrous metals account for more than 90% of the total volume used in the economy of metal, of which the main part consists of a variety of steel.
In addition to carbon in the iron and steel contains other components such as silicon, manganese, sulfur and phosphorus.
For iron and steel with the required properties (corrosion resistance, toughness, ductility, etc.) to add it alloying materials: aluminum, manganese, molybdenum, copper, nickel and chromium.
Steel - a mixture or solid solution of iron and carbon (and other elements), characterized by eutectoid transformation. The carbon content in steel is not more than 2.14%. Carbon gives alloys of iron strength and hardness, reducing the ductility and toughness.
Given that the steel can be added alloying elements, steel is called with not less than 45% iron alloy of iron with carbon and alloying elements (Alloy, High-grade steel).
In the ancient written sources was named special terms: "Ouzel", "Haralug" and "The way". In some Slavic languages, and today was called "Ouzel", for example in the Czech Republic.
Steel - the most important construction material for mechanical engineering, transport, construction and other industries.
Steel with high elastic properties are widely used in machine building and instrument making. In engineering, they are used for the manufacture of springs, shock absorbers, power springs for various purposes, in the instrument - for many of the elastic elements, membranes, springs, plates, switches, bellows extensions, suspensions.
The springs, spring machines and elastic elements are characterized by a variety of instruments of shapes, sizes, and various operating conditions. Feature of their work lies in the fact that for large static, cyclic or shock loads are not allowed residual strain. In this regard, apart from all spring alloys, mechanical properties, characteristic of all construction materials (strength, ductility, toughness, endurance), must possess high resistance to small plastic deformations. In the short-term static load resistance of the small plastic deformation is characterized by the elastic limit, the long-term static and cyclic loading - relaxation resistance.
