what is 3105 aluminum sheet?

3105 aluminum plate belongs to a series of Al-Mn alloy, good rust resistance, good electrical conductivity, including 98% aluminum content, because the addition of 0.3% copper content, electrical conductivity is 41%; 3105 aluminum plate can not be heat treatment and reinforcement, so the use of cold treatment to improve its mechanical properties: annealing state plasticity is high, semi cold hardening plasticity is good, cold hardening plasticity is low, weldability is good, poor cutting performance.

HuaWei aluminum can produce the widest 2800mm, the thickest hot rolled 3105 aluminum plate, good performance, reasonable price, welcome to inquire and order.

3105 aluminum sheet for bottle cap material

In order to increase the demand of aluminum deep washing for bottle cap material, the wine industry gradually increases the use of aluminum for bottle cap material. A job in the wine industry
The environment is very strict, which requires structural materials to have a certain tensile strength, yield strength, elongation, compression resistance, deep drawing, and other properties,
In addition, considering the structure and use environment of the wine industry, wine bottle materials also need to have good food safety. An aluminum plate of common bottle cap material
The performance and safety of this kind of strength bottle cap material are difficult to meet.

The main thickness of 3105 cap material is 0.15-0.3mm, and the state is O state, H12, H14, H16, etc.

Applications for 3105 aluminum sheet

Mg, Mn and Si are added to 3105 aluminum sheet, thus, it has excellent correction resistance, formability and welding characteristics. Besides, it has average machinability and it can be increased in harder tempers than in annealed conditions. Oil lubricants should be used for all machining operations. The forming characteristics of 3105 aluminium sheet are pretty good by all conventional processes regardless of temper. But 3105 aluminum sheet does not respond to heat treatment except for annealing during cold working. The cold working characteristics are very good, even in the harder cold working tempers. For all the features above, 3105 aluminum sheet has a vast application in many fields.

A wrought alloy is generally comparable to 3003 in properties and characteristics. Typically used for building product applications, it can also be used for other industrial applications.

  1. Cap Material. Due to the excellent deep-drawability of3105 aluminum sheet, it satisfies the design requirements of different bottle mouths of wine products.
  2. Mobile Homes, Residential Wall Panels. 3105 aluminum sheet is used as a wall, even in a very humid environment, such as an island, it can easily form a dense alumina protective film on the surface, which has a strong corrosion resistance. If the film surface is scratched and damaged, new films can also be produced quickly.
  3. Other Usages. Color coated aluminum substrate, rain gear, lamp holder, shutters, etc. Anodized3105 aluminum sheet, the surface can be coated with rich colors, so that the lighting fixtures, rain gear and other products have a rich design sense, and do not change color for a long time。
