aluminium alloy coil 1070 aluminum material aluminium alloy coil price
1070 aluminum alloy is a commercially pure aluminum belonging to the 1xxx series. It is widely
used in various industries due to its excellent electrical conductivity, thermal conductivity, corrosion
resistance, and workability. Below is a detailed introduction to 1070 aluminum alloy.
Basic Characteristics
♦ Composition: Aluminum content ≥ 99.7% (with trace amounts of iron, silicon, and other impurities),
making it a high-purity industrial aluminum.
♦ Density: Approximately 2.7 g/cm³, lightweight.
♦ Melting Point: Around 660°C.
♦ Electrical Conductivity: Conductivity is about 61% IACS (International Annealed Copper Standard), close
to pure aluminum (62% IACS).
♦ Thermal Conductivity: Thermal conductivity is approximately 230 W/(m·K), making it suitable for heat
dissipation applications.
♦ Corrosion Resistance: Performs well in most environments, especially in oxidizing conditions where it forms
a protective oxide layer.
1070 Aluminum Alloy's Mechanical Properties
| Mechanical Property | O (Annealed) | H14 (Half Hard) | H18 (Full Hard) |
| Tensile Strength (MPa) | 60 - 95 | 95 - 125 | 130 - 150 |
| Yield Strength (MPa) | 25 - 55 | 85 - 110 | 120 - 140 |
| Elongation (%) | 30 - 40 | 5 - 15 | 1 - 5 |
| Hardness (HB) | ~20 | ~35 | ~45 |
| Elastic Modulus (GPa) | ~69 | ~69 | ~69 |
O Temper (Annealed): Optimal ductility, suitable for deep drawing and bending.
H14/H18 Tempers: Cold-work hardened for higher strength but significantly reduced ductility.
Conductivity: Maintains high electrical (~61% IACS) and thermal conductivity (~230 W/(m·K)) in all tempers.
Main Applications
Electrical Industry: Conductors, busbars, cables (due to good conductivity and lower cost than copper).
Heat Dissipation Components: Heat sinks, heat exchangers (excellent thermal conductivity).
Packaging Materials: Food foil, pharmaceutical foil (non-toxic, corrosion-resistant).
Decorative Materials: Reflectors, signage (good surface treatment properties).
Chemical Equipment: Corrosion-resistant containers, pipe linings.
Our Company Advantages

for customers.
2) World leading technology and equipment, full sets of imported vertical intelligent storage and logistic
manage ment system,and finishing lines which fulfill all the requirements on various kinds of Aluminium
plate, sheet and strip products.The finishing lines including trimming lines,tension leveling lines,air-floating
type quenching lines,coating line and packaging lines.
For example:
All automatic three-dimensional elevated warehouse from Dematic (USA)
In the raw material area, the intelligent crane is used to transport ingots, and the three-dimensional
elevated warehouse is used to automatically pick up the high-temperature coils produced by the hot
and cold rolling machines,and the temperature of the incoming coils is monitored, then the automatic
coil transport car is used in the finishing plant to arrange the route according to the process requirem
-ents, and the heavy materials are flexibly transported to the subsequent production line or the automatic
packaging line.
