Pre-1886
Precious metal
Electrochemical isolation without cheap electricity kept aluminium a showcase metal.
铝 did not arrive as a finished commodity. Hall–Héroult 1886 around USA / France still explains who makes it and which tests it sits in.
Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.
起源
Hall–Héroult 1886USA / France
年表
1825Ørsted / Wöhler isolation
Tiny samples of aluminium were scientific curiosities, costlier than gold in display culture.
1854Deville process
Henri Sainte-Claire Deville made aluminium a luxury metal for Napoleon III’s tableware lore.
1886Hall–Héroult
Independent US and French patents electrolysed alumina in cryolite — still the core cell chemistry.
1888Bayer process
Karl Bayer digested bauxite to pure alumina, feeding the cells.
1906Wilm duralumin
Age-hardening Al–Cu alloys made airframes think in aluminium, not wood and fabric only.
1919–1939Aviation sheet
Duralumin skins and spars defined interwar and WWII airframes.
1959铝 beverage can
Coors and later two-piece DWI cans created a closed-loop scrap stream.
1970s6000-series extrusions
Al–Mg–Si extrusions became architecture’s default curtain-wall metal.
1990sAuto BIW trials
Audi Space Frame and others proved aluminium bodies at a cost premium.
2010s–High-recycled can sheet
Used-beverage-can loops in some regions exceed 70% recycled content.
时代
1886–1945
Cell and airframe
Hall–Héroult plus duralumin put aluminium into aircraft and power lines.
1945–1970
Consumer metal
Pots, foil and early cans; hydroelectric smelters clustered on cheap power.
1970–2000
Extrusion architecture
6000-series profiles remade façades and window walls.
2000–now
Light vehicles and recycling
EV battery enclosures and high-scrap can sheet dominate the sustainability story.
里程碑
Hall–Héroult 1886
1888Electrolysis made aluminium an industrial metal.
Duralumin 1906
1959Precipitation hardening unlocked aircraft structure.
UBC loop
2010s–Beverage cans became a textbook closed-loop aluminium product.
Knowing this timeline is how to read a mill certificate without treating 铝 as timeless.
