OUR RED GOLD ALLOYS
OR316U
Color shade: pink (intermediate between 5N and the so-called “6N”)
- L*: 87.0
- a*: 8.8
- b*: 16.8
- c*: 18.9
Formulation: Ag 12%, Zn 1%
Level of g.r.: high
Crystalline grain: 30 ± 2 µm
Processing: all-purpose
Features:
- Slightly easier to use than a deep red gold alloy because the content of silver lowers the risk for cracking
- Slightly darker than classic 5N, lighter than deep red alloys
- Interesting pricing point
- Suitable also for lower titles
OR134R
Color shade: red (the so-called “6N”)
- L*: 86.6
- a*: 9.6
- b*: 15.4
- c*: 18.1
Formulation: Ag 5%, Zn 3%
Level of g.r.: very high
Crystalline grain: 15 ± 2 µm
Processing: all-purpose
Features:
- Particularly suitable to heavy use of torch soldering that usually embrittls the item
- Very resistant against cracking in general, can also prove useful where process control in general is an issue
OR134UL
Color shade: deep red (slightly darker than the so-called “6N”)
- L*: 86.1
- a*: 9.7
- b*: 15.1
- c*: 18
Formulation: Ag 3%, Zn 2%
Level of g.r.: medium
Crystalline grain: 25 ± 2 µm
Processing: mechanical working
Features:
- Low silver content and a medium level of grain refiners make up for a good balance between performance and pricing
- Excellent for all plastic deformation applications
- Suitable also for lower titles
