Small density, high strength, corrosion-resistant features. (The density is about half that of stainless steel, but the strength is slightly higher than that of stainless steel.)
This is used in extreme bicycles, racing cars, high-grade parts are used. And golf heads.
Close to the density of human bone, non-toxic. There are many medical uses for titanium alloys for artificial joints. Part of the human body implanted devices (pacemakers) and so on are using titanium to do the shell, to ensure the safety of contact with the human body.
Aluminum alloys:
Aluminum alloys are made of pure aluminum with the addition of some alloying elements, such as aluminum-manganese alloys, aluminum-copper alloys, aluminum-copper-magnesium hard aluminum alloys, aluminum-zinc Aluminum-manganese alloy, aluminum-copper alloy, aluminum-copper-magnesium hard aluminum alloy, aluminum-zinc-magnesium-copper super hard aluminum alloy. Aluminum alloy has better physical and mechanical properties than pure aluminum: easy processing, high durability, wide range of application, good decorative effect, and rich color. Aluminum alloy is divided into rust-proof aluminum, duraluminum, super-hard aluminum and other categories, various categories have their own scope of use, and have their own code for users to choose.
Aluminum alloy still maintains the characteristics of light weight, but the mechanical properties are significantly improved. The application of aluminum alloy material has the following three aspects: one is as a stressed component; two is as a door, window, tube, cover, shell and other materials; three is as a decorative and adiabatic material. Using the feature that aluminum alloy can be colored after anodic oxidation treatment, various decorations are made. The surface of aluminum alloy plates and profiles can be anticorrosive, rolling, painting, printing and other secondary processing, made into a variety of decorative plates and profiles, as decorative materials.
Ferroalloys:
Variety use As a steelmaking deoxidizer, the most widely used are ferromanganese and ferrosilicon. Strong deoxidizers are aluminum (ferroaluminum), calcium silicate, silicon zirconium, etc. (see steel deoxidation reaction). Commonly used as alloy additives are: ferromanganese, ferrochrome, ferrosilicon, ferrotungsten, ferromolybdenum, ferrovanadium, ferrotitanium, ferronickel, niobium (tantalum) iron, rare-earth ferroalloys, ferroboron, ferro-phosphorus, and so on (Table 1 Commonly used ferroalloys). Various iron alloys and according to the needs of steelmaking, according to the alloying element content or carbon content of many grades, and strictly limited impurity content. Containing two or more alloying elements of ferroalloys called composite ferroalloys, the use of such ferroalloys can be added at the same time to deoxidize or alloying elements, the steelmaking process is beneficial, and can be more economical and reasonable utilization of **** raw ore resources. Commonly used: manganese silicon, silicon calcium, silicon zirconium, silicon manganese aluminum, silicon manganese calcium and rare earth ferrosilicon.
Steelmaking with pure metal additives are aluminum, titanium, nickel and metal silicon, metal manganese, metal chromium and so on. Some easily reducible oxides such as MoO□, NiO, also used in place of ferroalloys. In addition, there are nitrided ferroalloys, such as nitrided ferrochrome, ferromanganese, etc., as well as mixed with a heating agent heating ferroalloys.
Copper alloy:
Brass The copper alloy with zinc as the main added element has a beautiful yellow color, collectively known as brass. Copper-zinc binary alloy called ordinary brass or simple brass. Three or more brass is called special brass or complex brass. Containing less than 36% zinc brass alloy consists of solid solution, has good cold working properties, such as zinc content of 30% of the brass is commonly used in the production of cartridge cases, commonly known as cartridge brass or seven three brass. Containing 36 to 42% of zinc between the brass alloy by and solid solution composition, which is most commonly used is 40% of zinc-containing six-four brass. In order to improve the performance of ordinary brass, often add other elements, such as aluminum, nickel, manganese, tin, silicon, lead and so on. Aluminum can improve the strength, hardness and corrosion resistance of brass, but the plasticity is reduced, suitable for the sea vessel condenser tube and other corrosion-resistant parts. Tin can improve the strength of brass and corrosion resistance to seawater, so called naval brass, used as ship thermal equipment and propellers. Lead can improve the cutting performance of brass; this easy-cutting brass is commonly used for clock parts. Brass castings are often used to make valves and pipe fittings.
Bronze Originally referred to as copper-tin alloy, after the brass, copper alloys other than white copper are called bronze, and often in the name of bronze before the name of the first major additive elements of the name. Tin bronze casting performance, good friction reduction performance and good mechanical properties, suitable for the manufacture of bearings, worm gears, gears and so on. Lead bronze is the modern engine and grinding machine widely used bearing material. Aluminum bronze has high strength, good wear and corrosion resistance, and is used for casting high load gears, bushings, marine propellers and so on. Beryllium bronze and phosphor bronze have high elastic limit and good electrical conductivity, suitable for the manufacture of precision springs and electrical contact components, beryllium bronze is also used to manufacture coal mines, oil depots and other use of non-sparking tools.
White copper copper alloy with nickel as the main added element. Copper-nickel binary alloy called ordinary copper; plus manganese, iron, zinc, aluminum and other elements of copper alloy called complex copper. Industrial copper is divided into two categories: structural copper and electrical copper. Structural copper is characterized by good mechanical properties and corrosion resistance, and beautiful color. This kind of copper is widely used in the manufacture of precision machinery, chemical machinery and ship components. Electrotechnical copper generally has good thermoelectric properties. Manganese copper, copper, copper, copper is a different amount of manganese manganese white copper, is the manufacture of precision electrical instruments, varistors, precision resistors, strain gauges, thermocouples and other materials.
