### substance | mixture:

Alloy
* Many alloys contain zinc, including brass, an alloy of zinc and copper
  - harden with age and usually surpass the strength of steels
* Most alloy contains chromium
  - irons
  - has corrosion resistance
  - is made of metal
* Some alloy consists of copper
  - is made of copper
* Some alloys are easier to anodize and dye than others
  - have superconductive abilities and others are used to make nuclear fuel pellets
* are a very important kind of mixture in modern life
  - defined by a metallic bonding character
  - for improving crystal life when using higher stress coatings such as magnesium fluoride
  - heat treatable and most are weldable
  - made when two or more metals are mixed together
* are metals composed of more than one metallic element
  - that consist of more than one element
  - with impurities
  - mixed metals that offer a wide array of specific material properties
  - mixtures, where at least one part of the mixture metal
  - prepared by mixing of metals on their molten state
  - the metals mixed with gold
  - used in a wide variety of applications
  - usually synthetic materials, developed by scientists for special purposes
* can also contain small amounts of non-metallic elements.
* contain atoms of different sizes, which distorts the regular arrangements of atoms.
* containing aluminum or magnesium are structurally strong and lightweight
  - rhenium also have many other applications
* electrodes with high hydrogen overvoltage for analytical use in voltammetry.
* improve creep and fatigue properties, but reduce corrosion resistance.
* is bicycle business shorthand for aluminium alloy
  - solid objects
* mixture of metals in certain composition.
* often have properties that are different to the metals they contain.
* show quite different properties compare to their constituent metals.
+ Impurity, Useful impurity: Chemistry
  * Impure materials are useful sometimes. Alloys are metals with impurities.
+ Metal
  * Most metals are solid at room temperature, but this does not have to be the case. Mercury is liquid. Alloys are mixtures, where at least one part of the mixture is a metal. Examples of metals are  aluminium, copper, iron, tin, gold, lead, silver, titanium, uranium, and zinc. Well-known alloys include bronze and steel.

### substance | mixture | alloy:

Aluminum alloy
* Some aluminum alloys exhibit hot short tendencies and are crack sensitive.
* are generally difficult to weld on earth, requiring special procedures.
* are the current metal of choice for interconnects
  - second largest group of alloys produced
* is the primary material for the exterior skin on modern aircraft.

### substance | mixture | alloy:

Brass
* Most brass does conduct heat.
* Most brass has conductivity
  - metallic luster
* Some brass does conduct electricity.
* are perhaps the least susceptible copper alloys to sulfide pitting
  - very thin pieces of brass and coppers are half that thickness
* contains zinc and possibly small amounts of lead.
* expands and contracts more than iron for the same changes in temperature.
* frequently contain lead in order to improve machinability.
  - pitch
* is albums
  - bronze
  - conductors
  - decoration
  - families
* is located in metal objects
  - orchestras
  - memorials
  - plates
  - sections
  - wind instruments
* tends to throw back the reflection of light making it harder to read.

### substance | mixture | alloy | brass:

Alpha brass
* inhibited against dezincification can however suffer pitting under some circumstances.
* is brass

Baritone horn
* Most baritone horns have the bell curved forward to help project the sound.
* is brass

Bugle
* are beads
  - brass instruments
  - herbs
* are located in boxs
  - brass bands
  - military bands
  - music stores
  - troops
  - musical instruments
  - used for music
* is brass
