What are Alloys?

An alloy is a mixture of chemical elements, at least one of which is metal. Unlike compounds with metal bases, alloys will retain all of the properties of metals in the resulting material, such as conductivity, ductility, opacity, and gloss, but may have different properties from pure metals, such as increased strength or hardness. In some cases, alloys can reduce the overall cost of the material while retaining important properties. In other cases, mixtures confer synergistic properties on the constituent metal elements, such as corrosion resistance or mechanical strength. 

An alloy is defined by its metal-binding properties. Alloy composition is usually measured by mass percentage in practical applications and atomic fraction in basic scientific research.  Alloys are usually classified as substitute alloys or interstitial alloys according to the arrangement of atoms forming them. They may be further classified as homogeneous (consisting of a single-phase), heterogeneous (consisting of two or multiple phases), or intermetallic compounds. An alloy may be a solid solution of a metallic element (a single phase in which all metallic grains (crystals) have the same composition) or a mixture of metallic phases (two or more solutions that form different crystalline microstructures within the metal). 

Examples of alloys include red gold (gold and copper) platinum (gold and silver), pure silver (silver and copper), steel or silicon (iron and non-metallic carbon or silicon respectively), solders, brass, tin, duralumin, bronze, and amalgam. 

Alloys can be used in a wide range of applications, from steel alloys (used in everything from construction to automobiles to surgical tools) to special titanium alloys for the aerospace industry to beryllium copper alloys for sparkless tools.

What are the Five Metal Alloys?

1.    Steel alloy

Alloy steels include nickel steel, chromium steel, manganese steel, tungsten steel, vanadium steel, and molybdenum steel. Nickel-steel alloy has better elasticity, less brittleness, and higher tensile strength. It also has greater ductility and hardness. It is used to make machine parts, shafts, boilerplates, etc. Steels containing 30% nickel are called invar alloys, which have a low coefficient of thermal expansion.

Chromium steel has greater ultimate strength. It is used for ball bearings, crushers, permanent magnets, shavers, rolling mill rolls, tableware, and so on. It contains between 1% and 2.5% chromium. If the percentage of chromium is high (12%), this alloy is called stainless steel, which is acid resistant, stain and rust-resistant, and can be used in surgical instruments, utensils, decorative accessories, etc. 

Manganese steel contains 2% manganese and is hard and strong. It has high resistance, non-magnetic properties, and a low thermal expansion coefficient. Used for heavy earthmoving equipment, crusher jaw plate, railway track, etc.

Tungsten steel contains 5 to 7 percent tungsten. This is used for lathe tools, drills, chisels, cutters, reamers, etc. 

Vanadium steel has high tensile strength and yield strength. Used for high-speed tools, locomotive castings, engine frame, chassis, crankshaft, axle, spring, etc. 

Molybdenum steel contains 0.2% to 0.3% molybdenum (two other metals, chromium, and manganese, are usually used with molybdenum). It also has a high tensile strength at high temperatures. Used for shafts, gears, axles, automobile, and aircraft parts.

2.    Copper alloy: 

Brass and bronze are important alloys of copper. Brass is an alloy of copper and zinc (70% to 85% copper). It is very resistant to corrosion and can be rolled into sheets, turned into tubes, drawn into wires, and cast into the desired shape. 

Add some nickel to the brass to make German silver or nickel silver. 

Bronze is an alloy consisting mainly of copper and tin. Gunmetal, bell metal, and phosphor bronze are various types of bronze. Gun metal contains copper, tin, and zinc. Bell metals contain copper and tin. Phosphor bronze contains copper, tin, and phosphorus.  Manganese bronze contains copper, manganese, aluminum, lead, iron, and zinc, and speculum metal contains copper and zinc. 

Different types of bronze have different uses. They are used in the manufacture of guns, bearings, clocks, underwater structures, axles, and axles. 

3.    Aluminum alloy: 

Aluminum can be alloyed with copper, silicon, magnesium, manganese, nickel, and iron. 

4.  Nickel alloy: 

Monel metal and nickel silver are two nickel alloys. Monel metal contains copper and small amounts of nickel and other metals. Nickel silver or German silver contains copper (50 to 80 percent), zinc (10 to 35 percent), and nickel (5 to 30 percent). It is very white and has good corrosion resistance. Used to make scientific instruments and utensils. 

5.  Magnesium alloy: 

The metallic and electronic metals are magnesium alloys. Dow contains magnesium (87 percent to 97 percent) aluminum (4 percent to 12 percent) and manganese (0.1 percent to 0.4 percent). Electronic metals contain magnesium (95% to 96%), zinc (4%), and small amounts of iron, copper, and silicon. These alloys are very light. They are easy to operate.  They are used to make aircraft parts, furniture frames, and so on.
