YKK 05 RA Aluminum Metal Chain PBR14 Dyed size 5 Zipper Type

About YKK 05 RA Aluminum Metal Chain PBR14 Dyed size 5 Zipper Type

• 05  This likely means #5 size for the zipper chain. In YKKs Metal Standard zippers, size 5 (5R or 5M) is available including in chain versions.  

• Aluminum Metal  The chain (teeth) is made of aluminum alloy. As per YKK: aluminum-alloy metal zippers are lighter than copperalloy ones. PBR14 (Dyed)  This refers to the tape code.

• • PB14 is a known tape code in YKKs specification for metal zippers. For example, in YKKs Functional Fastening catalogue, they mention PE14, C14, for size 5 metal zipper. 

  • Dyed suggests the tape is not in its natural color but has been dyed to a specific shade.

From YKKs publicly available material, the following applies for aluminummetal zippers (size 5 and similar):

1. Material & Properties

   • Aluminum-alloy elements: Lighter than copper alloy. 

   • Because aluminum is softer, it will be more prone to scratches / wear due to friction.

   • Susceptible to chemical damage: YKK explicitly cautions against post-processing that involves acid wash, alkali wash, high-concentration bleach, etc.

   • Compatibility: According to YKK, aluminum alloy elements should not be used with copper alloy sliders. 

2. Sizes / Configuration

   • Available in size #5 for aluminum metal zippers in standard metalzipper range.

   • Supported in Chain type (i.e., continuous chain) as well. 

3. Tape / Cord

   • Tape can be dyed (so PB14 dyed seems plausible).

   • YKKs Fastening Catalogue lists tape color variation + tape types for Metal Zippers. For example, for size 5 metal zipper (chain included) with aluminum elements: tape code T508 etc for dyed tapes. The YKK India catalogue gives tolerances for zipper dimensions: Maximum Tolerance for metal zippers when measuring chain length.

4. Care / Usage

   • Because of the chemical sensitivity: Avoid aggressive chemical washing / posttreatment. 

   • Use in lighter / fashionweight fabrics: YKK recommends aluminum-alloy zippers for fashion use given the lighter weight. Testing is recommended: Given that chain is dyed tape, tests for color fastness, wash durability, etc. would be prudent.
