State an advantage of using wood
Considered to be a warm and comforting material
State a disadvantage of using wood
Wood typically needs a finish, which adds cost and time
What is a ferrous metal
A metal that contains iron therefore making it magnetic
What is a non-ferrous metal
Metal that doesnt contain iron, therefore it isnt magnetic
State two advantages of each hardwood
Birch- strong, durable Beech-strong, durable Balsa-lightweight, buoyant Walnut- strong, durable Oak-strong, durable Ash-strong, good elasticity Mahogany- easy to work with, finishes well Teak-strong and surable
State 2 advantages for each softwood
Scots pine- strong, easy to work with
Spruce- strong, resistant to splitting
Cedar- durable outdoors, easy to work with
Reds pine- strong, straight grained
Douglas fir- durable with good workability
State two advantages of each ferrous metal
Cast iron- strong, tough
Mild steel- easy to weld, ductile
Tool steel- resistant to wear, brittle
Stainless steel- corrosion resistant, tough
State two advantages of each non-ferrous metal
Zinc- casts well, ductile
Copper- tough, conducts heat and electricity well
Aluminium- good strength-to-weight ratio
Brass- polished well, conducts heat and electricity well
Duralumin- stronger than pure aluminium, good strength-to-weight ratio
State an advantage of using metals
They can come in a range of colours
