Unit 45- Typical materials
Metal
Gold
properties
In mass, gold is a yellow-colored metal. Gold is a good conductor of electricity and heat. It is inert and a good reflector of infrared radiation. Gold is usually alloyed to increase its strength.
additive manufacturing
3D printing
Aluminium
properties
It is ductile and malleable.
The high purity aluminium has a much greater resistance to corrosion than the ordinary steel.
additive manufacturing
Extremely fine metal powder is partially melted
Steel
properties
The physical properties of steel include high strength, low weight, durability, ductility and resistance to corrosion. Steel, as we all know, offers great strength though it is light in weight.
additive manufacturing
Additive manufacturing (AM) of steels involves the layer by layer consolidation of powder or wire feedstock using a heating beam to form near net shape products.
silver
Properties
Silver ( Ag ) is a white, soft, lustrous, very ductile and malleable metal.
It is a very good conductor of electricity and heat.
It has the highest electrical conductivity of all metals, but the high cost of it has restricted us from using it
additive manufacturing
For the additive manufacturing industry is its use in dental alloys, electrical contacts and high capacity batteries.
titanium
properties
Titanium is lightweight, strong, and extremely resistant to corrosion. It has a shiny, dark grey/silver appearance and is non-toxic in the human body (which is why it is used in surgical tools)
additive manufacturing
titanium alloys are used in additive manufacturing to produce a wide range of industrial components, including blades, fasteners, rings, discs, hubs and vessels.
