Quais são as diferenças entre 1050 folha de alumínio e outras folhas de alumínio?

Comparação entre 1050 folha de alumínio e outros tipos de folha de alumínio

1050 a folha de alumínio é um material de folha de alumínio de alta pureza com um teor de alumínio superior a 99.5%. É amplamente utilizado em embalagens de alimentos, capacitores, correias de cabos e outros campos. Comparado com outros tipos de folha de alumínio, 1050 a folha de alumínio tem as seguintes características e vantagens:

Composição química e pureza

1050 folha de alumínio: aluminum content ≥99.5%, belonging to industrial pure aluminum.
Other aluminum foils: como 1060 folha de alumínio, aluminum content ≥99.6%; 3003 aluminum foil contains a small amount of manganese and copper, belonging to aluminum-manganese alloy.
Comparação: The high purity of 1050 aluminum foil makes it excellent in corrosion resistance and conductivity, but its strength is relatively low.

1050 propriedades mecânicas

Propriedades	1050 folha de alumínio	1060 folha de alumínio	3003 folha de alumínio
Resistência à tracção	60-100 MPa	70-110 MPa	85-145 MPa
Força de rendimento	30-50 MPa	40-60 MPa	34-120 MPa
Alongamento	≥23%	≥23%	≥10%

1050 folha de alumínio: has high plasticity and good formability, mas baixa resistência.
1060 folha de alumínio: higher purity, slightly higher strength than 1050, but slightly worse plasticity.
3003 folha de alumínio: higher strength, but not as good plasticity as 1050 e 1060.

Resistência à corrosão

1050 folha de alumínio: has good corrosion resistance in oxidizing media, and can form a dense aluminum oxide passivation film on the surface.
Other aluminum foils: como 3003 folha de alumínio, due to the presence of a small amount of manganese and copper, the corrosion resistance is slightly inferior to 1050.

Processability

1050 folha de alumínio: has excellent forming processability and is suitable for deep drawing and calendering.
Other aluminum foils: como 3003 folha de alumínio, the processability is also good, but not as good as 1050.

Application areas

1050 folha de alumínio: widely used in food packaging, capacitores, cable belts, aluminum foil gaskets, etc..
1060 folha de alumínio: mainly used for food packaging, embalagens farmacêuticas, etc..
3003 folha de alumínio: suitable for applications requiring higher strength, such as architectural decoration, folha de recipiente, etc..

Cost and price

1050 folha de alumínio: simple production process, relatively low price.
Other aluminum foils: como 3003 folha de alumínio, due to the addition of alloy elements, the cost and price are relatively high.

1050 aluminum foil has significant advantages in areas such as food packaging due to its high purity, excellent formability and corrosion resistance. Compared with other aluminum foils, 1050 aluminum foil has lower strength, but its high purity and good processability make it excel in applications that require high electrical and thermal conductivity.
