MECHANICAL WORKING ALLOYS FOR YELLOW GOLD

mechanical working alloys for yellow gold

Jewels that are lighter, thinner, harder, easier to produce... How to combine all these requests from our customers in a product? Well, that is our everyday work! Here are some of the latest formulations we developed for the production of jewelry by mechanical working processes.

 

B182T

Title: 750‰

Formulation: Ag 63%, Zn 2%

Hardness (as cast/after age-hardening 300ºC x 90'): 130 HV / 180 HV

Features:

  • Highly deformable, easy to process
  • Perfect on CNC milling and continuous casting processes
  • Light yellow color (2N, "Italian" color) with extremely high shininess

YG281U

Title: 750‰

Formulation: Ag 34%, Zn 15%

Hardness (as cast/after age-hardening 450ºC x 90'): 135 HV / 210 HV

Features:

  • As low as 34% silver in the formulation!
  • Casting in closed systems, sheet and wire deformation
  • Light yellow color

Y298T

Title: 585‰

Formulation: Ag 22%, Zn 13%

Hardness (as cast/after age-hardening 450ºC x 90'): 140 HV / 190 HV

Features:

  • Conceived for making TIG tube in 585‰. Can be used also in 375‰
  • High chemical resistance to hollowing
  • Harder and more thermally resistant than similar products in the range

Y144HN

Title: 375‰

Formulation: Ag 18%, Zn 13%

Hardness (as cast/after age-hardening 450ºC x 90'): 150 HV / 195 HV

Features:

  • Conceived for making TIG tube and hollow chain. Can be used also in 585‰
  • Good chemical resistance to hollowing
  • Good thermal resistance to annealing cycles
