What “the material” actually is
구리 is sold as grades, not as a single substance. Chemistry Cu, density 8.96 g/cm³, heat band 1085 °C.
This atlas treats 구리 as a system: mill route, coatings, tests and the cavity it sits in.

구리 is one of 32 materials in this atlas, grouped under metals: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.
Scores compare 구리 with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.
Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
깊이 읽기
Deep dive: 구리
구리 (Cu) is a family of grades whose density 8.96 g/cm³, heat band 1085 °C, and fire letter A1 metal.
Heat, fire and insulation
Conductivity note: ~400 W/m·K. Insulation score 6/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
Fire letter in editorial use: A1 metal. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
How it is made and used
Origin: Chalcolithic / industrial electrorefining 1860s, Cyprus / global. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span buildings to defence / safety. Pairings matter: aluminum.
Market and circularity
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 78/100. Ask which scrap, which certificate, which year.

Thermal mark 6/100 versus the atlas. Conductivity note: ~400 W/m·K.
What is the density band?
8.96 g/cm³
How is it made?
Origin story: Chalcolithic / industrial electrorefining 1860s (Cyprus / global).
Can it be recycled?
Circularity mark 78/100 — editorial, route-specific.
Typical melting or failure heat?
1085 °C
What should it be paired with?
aluminum: The lighter conductor when cross-section is free.
Where is it specified?
Buildings, transport, energy and consumer goods — see the uses chapter.
