1350 aluminum is a high-purity (99.5% min) electrical-conductivity grade in the 1xxx series. This guide covers its physical and chemical properties, main applications, pros and cons, common tempers, and how it compares with 6061 and 8000 series alloys.
Introdução
1350 aluminum alloy is a pure (1xxx-series) alloy known for excellent electrical conductivity. It contains at least 99.5% aluminum, which gives it higher conductivity than most other aluminum alloys. That purity makes it a staple in electrical applications where conductivity matters more than strength.
What Is 1350 Aluminum Alloy?
1350 aluminum is a pure aluminum alloy with excellent electrical conductivity. It is soft and formable, which suits jobs where shaping matters. Because of its high thermal and electrical conductivity, it is widely used in electrical conductors and cable wraps.

Principais aplicações do alumínio 1350
1350 aluminum is popular because it conducts electricity well, resists corrosion, and costs less than copper. It is used across complex electrical systems and everyday components alike. Its light weight and formability suit both busbars and fine electronic parts.
Condutores elétricos e envoltórios de cabos
1350 is widely used for electrical conductors and cable wraps. Its conductivity makes it a practical copper alternative where weight matters. You will commonly find it in power cables, busbars, and transformer windings.

Its low weight simplifies handling and cuts transport cost. Corrosion resistance also extends service life in tough conditions. For EC-grade wire, see our Fio de alumínio 1350-O/H19.
Trocadores de calor e tubos de radiadores
Beyond electrical use, 1350 has good thermal conductivity for heat exchangers and radiator tubes. These parts move heat between fluids efficiently. In car radiators it helps control engine temperature, and the same applies to air conditioning and refrigeration systems.
1350 is also light, which helps in transport and compact assemblies. Its formability supports the thin-wall tubes these systems need.
Prós e contras do alumínio 1350
1350 is valued for high conductivity and purity, plus corrosion resistance and formability. Its main drawback is low strength, which limits use in high-stress parts. The table below sums up the trade-offs.
| Prós | Contras |
|---|---|
| High Electrical Conductivity: Excellent for power cables and busbars. | Low Mechanical Strength: Not suited to high-load parts. |
| Boa resistência à corrosão: Holds up in moist or corrosive settings. | Limited Heat Resistance: Not ideal for high-temperature service; follow SDS guidance for handling. |
| Leve: Major weight savings versus copper and steel. | Limited Wear Resistance: Softer and less durable than many alloys. |
| Boa conformabilidade: Easy to shape and fabricate. | Limited Hardness: Not for applications needing high hardness. |
Temperaturas comuns do alumínio 1350
1350 is supplied in several tempers that trade softness for strength:
- O Temperamento: Fully annealed, soft, and ductile — best for bending and forming.
- H12 Temper: Strain hardened and partially annealed, with slightly higher strength.
- Temperamento H14: Strain hardened more than H12, while keeping good formability.
- H16 Temper: Further strain hardened for more strength and stability.
- H18 Temper: The highest-strength 1350 temper, used where maximum strength is needed.
Comparação do alumínio 1350 com outras ligas
1350 leads on conductivity, but other alloys fit different needs. Knowing the differences helps you pick the right material. The tables below compare it with 6061 and 8000 series.
1350 vs. 6061 Aluminum
1350 and Alumínio 6061 serve different roles. 1350 is a pure alloy built for conductivity, while 6061 is a stronger, more corrosion-resistant structural alloy. Use 1350 for conductors and 6061 for machined or structural parts.
Here is the physical properties comparison:
| Propriedade | 1350 Alumínio | Alumínio 6061-T6 |
|---|---|---|
| Densidade | 2,70 g/cm³ | 2,70 g/cm³ |
| Resistência à tração final | 68-190 MPa | 310 MPa |
| Resistência à tração | 25-170 MPa | 270 MPa |
| Alongamento na ruptura | 1.4-30% | 10% |
| Resistência à fadiga | 24-50 MPa | 96,5 MPa |
| Resistência ao cisalhamento | 44-110 MPa | 207 MPa |
| Condutividade elétrica | 61% IACS | 40% IACS |
| Soldabilidade | Excelente, fácil de soldar | Good, but needs precise technique |
| Usinabilidade | Fair, needs sharp tools | Excellent, good for precision machining |

1350 vs. 8000 Aluminum
1350 is very pure and highly conductive, while 8000 series adds more silicon and other elements. 8000 can offer better corrosion resistance in some builds, but 1350 remains the EC-grade choice for conductors. Pick based on purity, conductivity, and any added alloying needs.
Here is the physical properties comparison:
| Propriedade | 1350 Alumínio | Alumínio série 8000 |
|---|---|---|
| Densidade | 2,70 g/cm³ | 2,63-2,80 g/cm³ |
| Dureza (Brinell) | Aproximadamente 23 HB | Generally harder due to alloying |
| Resistência à tração final | 95-115 MPa | 99-104 MPa |
| Condutividade elétrica | Aproximadamente 61% IACS | Aproximadamente 60,5% IACS ou superior |
| Resistência à corrosão | Alto, devido à pureza | Higher due to added elements |
| Aplicativos | Electrical conductors, high-purity uses | Secondary distribution wires, terminations |
Conclusão
1350 aluminum delivers excellent electrical conductivity and good corrosion resistance, but its trade-off is low mechanical strength and limited hardness. That makes it ideal for conductors and busbars, yet unsuitable for structural or high-load parts.

Perguntas frequentes
Qual é a diferença entre o alumínio 1050 e o 1350?
Both are 99.5%-minimum pure alloys, but 1050 is used for general-purpose work while 1350 is tuned for electrical use. 1350 keeps iron and silicon low to protect conductivity. Choose 1350 when electrical performance is the priority.
Qual é a diferença entre alumínio 1350 e 8000?
1350 is the EC-grade conductor choice, built for maximum conductivity. 8000 series adds silicon and other elements that can improve properties like corrosion resistance in some designs. The right pick depends on whether conductivity or added alloying benefits matter more.
Qual é a diferença entre o alumínio 1350 O e o 1350 H19?
1350-O is fully annealed, soft, and easy to bend or form. 1350-H19 is strain hardened to the highest strength and hardness in the range. Use O for forming and H19 where strength matters most.
What is the difference between 1350 and 1370 aluminum?
1370 is also an EC-grade alloy but with a higher minimum purity of 99.70% aluminum, giving slightly better conductivity than 1350’s 99.50% minimum. Both are used for electrical conductors; 1370 is chosen when the application calls for the higher-purity grade.
Is 1350 aluminum suitable for structural applications?
No. 1350 has low tensile strength and hardness, so it is not meant for load-bearing or structural parts. It is best reserved for electrical conductors, busbars, and similar non-structural conductive uses.
