1

metals consists mostly of iron (ex: steel)

Ferrous

2

contain little or no iron (ex: copper and aluminum)

Non-ferrous

3

process of forming a material into a particular shape by pouring it in a fluid state into a mold, and then letting it harden

Casting

4

Shapes are produced by forcing semi-molten material through a die with a pressure ram. Long linear shapes are produced.

Extrusion

5

Formed by hammering, pressing, or rolling metal into the desired configuration

Forging

6

Accomplished b y buffing, grinding, polishing, or otherwise texturing the metal surface for a specific appearance

Mechanical finishes

7

Involve the reaction of various solutions on the metal surface. These finishes may or may not have an effect on the performance of a metal surface.

Chemical finishes

8

are either materials applied to the metal or formed by the metal itself through a chemical or electrochemical process

Coatings

9

The reddish brittle coating formed on the surface of iron esp. when exposed to moisture and air

Rust

10

The process or result of combining oxygen to form an oxide

Oxidation

11

The process by which steel is coated with a layer of zinc

Galvanizing

12

commonly referred to as anodized finishes;

Electrolytic finishes

13

aluminum can be covered with a protective or decorative film or another metal usually by electrodesposition

Electroplating

14

This finish creates a different feeling in that colors are glassy

Porcelain or Vitreous Enamel

15

a malleable, ductile, magnetic, silver-white metallic element from which pig iron and steel are made

Iron

16

a hard, brittle, non-malleable iron-based alloy; contains the most carbon; hardest among all irons

Cast Iron

17

a tough, malleable, relatively soft iron that is readily forged and welded; contains the least amount of carbon

Wrought Iron

18

Crude iron that is drawn from a blast furnace and cast into pigs in preparation for conversion into cast iron, wrought iron, or steel

Pig Iron

19

An oblong mass of metal that has been poured while still molten into a mold of sand, esp. a mass of iron from a blast furnace

Pig

20

Any of various iron-based alloys having a carbon content less than that of cast iron and more than that of wrought iron; used as a structural material

Steel

21

an iron alloy that is corrosion resistant because of addition of chromium; popular use as column covers, railings, kitchen sinks, and fine eating utensils

Stainless Steel

22

Steel that has properties made up mostly of carbon

Carbon Steel

23

Steel that includes silicon, which allows the steel to minimize energy loss during electrical applications

Electrical Steel

24

To coat a metal esp. aluminum or magnesium, with a hard, noncorrosive film by electrolytic or chemical action

Anodize

25

The gradual deterioration of metal by chemical action, as when exposed to weather, moisture, or other corroding agents

Corrosion

26

a ductile, malleable, silver-white metallic element that is used in forming many hard, light alloys; highly resistant to corrosion; excellent thermal and electrical conductor

Aluminum

27

a ductile, malleable, reddish-brown metallic element that is an excellent conductor of heat and electricity and is widely used for electrical wiring, water piping, and in the manufacture of alloys, as bronze and brass

Copper

28

an alloy of copper and zinc; bright yellowish

Brass

29

an alloy of copper and tin with phosphorous; rich golden-brown

Bronze

30

a lustrous, low-melting, bluish-white metallic element used in plating and in making alloys and soft solders

Tin
