Metals Flashcards
Ferrous?
Contains iron
Non ferrous
No iron
Examples of non ferrous
Aluminium
Copper
Examples of ferrous
Mild steel
Stainless steel
Cast iron
High carbon steels
Properties of aluminium
Lighetweight
Ductile
Corrosion resitance
Conducive
Low density
Well machined
Cons of aluminium
ENergy inetnsive process
Can be expenisve
Not as strong as steel
Pros of aluminium
Widely recyled
Low energy to recyle
Low weight
Compared to steel what is aluminiums stiffness and density
about a third of it
Uses of aluminium
Drink Cans
Aircraft bodies
Cooking shit
Foil
What si alumnium when as a raw material
relatively soft with low strength
Properties of copper
Ductile
Mallable
Conductive
Corrsive resiatnces
Uses of copper
Wiring
PCB circuits
Water pipes and tanks
Plumbing and heating
Properties of mild steel
Tough
Ductile
malleable
High tensile strenth
Cons of mild steel
Poor corrosive resitance
Cannot be hardened expect for case hardening
Uses of midl steel
General purpose engineering
Structural material
nuts
Bolts
Outer panels for white goods
What metal can be used in MIG and TIG
Alumnium
What metal can be used in brazing adn sodlering
copper
High carbon steel proeprties
High reistance to wear
Cons of high carbon steel
Brittle
Poor corrsive restance
Uses of high carbon steel
Hand and machien cutting tool s
Stainless steel properites
Tough
Hard
Corrosive reistances
Very durable
Simialr to mild steel
Ductile
Uses of stainless steel
Kicthen shit
cutlery
surgical shit
Cast iron proeprities
Cost effective
Heavy
Rigid
Good compression strength
Casts well
condctive
high melting point
uses of cast iron
pans
machien parts
disc brakes
use of zinc
protects other metals
galvanisign
why is zinc used in galavansiign
does not corrode
tin proeprties
soft
conducitve
malleabel
ductile
corrosive resit
anti contamination
low melting point
uses of tin
sodlering
proeprties of tungsten
very very tough
very dense
restiant to corrosion
high tensile strength
very durable
stupid high metling point
what is tngsten in pure form
very soft
what is one of the hardest forms of tungsten
tngsten carbide
because fo tungstens strength when made in compounds what is it used for
high speed cuttign tools
tups for ciruclar saws
drill bits
giv some emtal alloys
bronze
brass
tungsten carbide
bronze proeprties
tough
corrosive retsance
can be cast
harder than copper
low friction coefficint
high fatigue restance
uses of bronze
statues
coins
bearinings
electrical products
what to always add on the end of a material
ALLOY
proeprties of brass
corrosion restatnce
good thermal conductor
low metling point
elcrticla conducitve
cast well
uses of brass
where low friction require
insrtuments
why will most shit never be made of pure alimium
expensive
not sutiable for structrual shit
with other shit very good
very good rpoerties in alloy form
ways to meausrue how metals are udner laods
