ALLOYS

It is a mix of metals and others elements( metals or not) very ised in industrially to inprove the properties of metals

what are metals?

metals are found in nature forming minerals or in a pure estate. the process of estracting and transforming is called metallurgy

Phisical

Good electric,termal and sounel conductor

Characterieste shine

Pense and heavy materials

Chemical

Ferrous materials Get oxidation

Non ferrous metals resist better to oxidation

Mechanical

Very ductile

Very malleable Very resistant to sresses

Ecologhical

They have durability

They are recyclabe➡️ steal aluminiun and copper are the most recyclabe metals They are rensable

Ferrous metals

Good macnetic Properties Very bittle and Difficult Handle

Iiron

Good mechanical properties It is strong malleable and ductile

Steal

Black colour, brattle and bard Resist Better to corrosion

Foundry

No ferrous materials

Soft and reed colour Higt termal and electrical conductivity Resistant to corrosion

Copper

Softh and white colour Resistant to corrosion Veri malleable and ductile

Tin

Blue grey We use it in glavanizations

Zinck

Soft and heavy Hight termal conductivity Very malleable

Lead

Low densityVery ligt Higth conductivity Resistant to corrosion

Aluminiun

Ecologycal imact of metals

Mining can cause problems such as pollution, large consuption of resources and lanscape degracation
