As a green bottle cap material, aluminum is more and more demanding. 8011 aluminum foil is a main kind. How much do you know about it? Let’s have a look.
8011 aluminum foil can be used as the raw material of anti-counterfeit aluminum bottle caps. It can be divided into casting and hot rolling. It also has different tempers such has H16 and H18, which can satisfy the requirements of different industries.
8011 H18 bottle cap material
8011 H18 bottle cap material is mainly applied to stamping shallow caps, which can be cast and rolled. The process: cold rolling-foil rolling-straightening-slitting-packaging and other processes. It does not require annealing treatment, so the production period is the shortest and the price is relatively cheaper.
8011H16 bottle cap material
8011H16 bottle cap material is an important member of hot-rolled aluminum anti-theft cap material. Its specification:
Thickness range: 0.15-0.27mm
Thickness tolerance: ± 0.005mm
Width: 330-1000mm
Width tolerance: ± 1mm
Tensile strength: 150-165Mpa
Elongation rate> 2%
As for its quality, it should be of smooth surface, no obvious roll marks, no obvious defects such as oil stains, scratches, bright strips, etc. The earring rate should be less than 3%.
Its production needs more steps: cold rolled-annealing-foil rolled-stretch bending-slitting. After the finished rolls are produced, they must go through a number of processes such as cutting, painting, drying, multiple stamping, and anti-counterfeiting markings to produce qualified bottle cap materials. For medical caps and wine bottle caps, there are some difference in the process of annealing.
Quality aluminum cap material needs strict and advanced processing management. Haomei Aluminum, with rich experience and state-of-art equipment can make it. Welcome to send inquiry to us.
